I got the same text from 72166. I called the number in the back of my Chase card to confirm. It’s legit. Turn out someone was trying to use my card online and Chase detected it. So my now my card is canceled and they will send me a new one.
I called the number on the back of my card after receiving a text from 72166. They confirmed that the text was real and the number is also real. The customer service person recommended always calling the number on the back of your card if this happens. So..they had to cancel my card and they are sending me a new one. Good job by Chase!!
Received fraud alert text which was legit. Phoned Chase directly using the # on the back of my card. Card is still in my possession but has been compromised somehow.

The text info was legit. The amount listed and the company that attempted the charge showed up on my account. I did not, however, call this number (from the text) to verify and cancel my card. I called the number on the back of the credit card.
Called the number on the back of my card. There were fraudulent charges that matched the charges listed in the txt Fraud Alert. Always call the number on the back of your card; however, scammers always lurking.

Not a legit chase number. Call the number on the back of your card instead

Got a text from 72166 saying that suspicious activity was found on my card, directing me to text Yes or No back to confirm I made the transaction. I texted NO as i did not make the transaction, and they texted back to call that number. I suspected scam as usual and instead called the number on the back of my card. The Chase fraud department representative confirmed that the fraudulent transaction was actually there (for what it's worth it was a denied transaction attempt at Shell in Maryland). I had the same information in my inbox as well, with a hyperlink directing to the legit Chase Fraud Detection website. I have the card with me, never lost it or had someone use it, so the card info was somehow hacked (merchant terminal or internet is Chase's business to find out).
I received a VM instructing me to call this number, identifying themselves as Chase Fraud Division. Instead I phoned the number on the back of my Chase card, and they confirmed that there is nothing wrong with my card and instead the VM was fraud. People suck.

This is legit. Called the number on the back of the card and verified this number is a direct number to their Fraud Department.
Total fraud. They pose as Chase to get your information, but it's not Chase. If you get a text or call from this number, just call the number on the back of your credit card. If what they're claiming is legit, then the people at that number will be able to help you. Why risk giving your information to a number that you have to go to a scam review website to see if it's real? No reason at all when you're given a number right on your card. Better safe than sorry.
Never call a number given to you and your Message or mailbox. Always use the number on the back of your card.
What makes this site a bit useless is that there are both those who are adamant that it is a legitimate number, and that it is fraudulent. Both sides claim that they have called Chase to confirm their "side." I'm one more who was notified and called the number on the back of my card to confirm the above number is legit. Why are some claiming it is not? Is Chase that messed up? Do some just enjoy putting misinformation out there?

This is a really good SCAM. Somehow they knew I had a balance on my Chase credit card, and wanted me to pay it. I had been having a problem with my AutoPay just two days before, so I thought this was a follow up to the phone calls I had already made to straighten it out. So I STUPIDLY entered my PIN into the phone when they asked. That is the first sign this is a SCAM.
Several days later, the real CHASE sent me a text saying there was a $1 charge that looked fraudulent (it was). I then called Chase and then I realized my stupid conversation on the phone is probably what corrupted my account. I asked Chase if 800-454-9078 is a legit number. They said NO. And they also said they would never ask for my PIN. So I was stupid and now I have to change everything.
California Jul 19th, 2019
This seemed really legit, but most likely a Scam! I checked my account and No charges? yeah, scammers are getting really good now and days, trust no one, unless you see it for yourself.
Got the number by clicking through on a fraud email from Chase (I'd also received a text alerting me to suspicious activity). Called and provided the numbers on the back, plus my mother's maiden name. They verified the fraudulent charges and ran through other pending charges to make sure they were valid. Called the number on the back of my card later in the day to confirm that my new cards were being sent overnight and they verified everything that had happened earlier in the day. It's legit.
This is Chase. I called this number, they were able to give me 5 transactions: 2 I didn't make and 3 legit transactions. How would the person at this number know my legit past transactions if it was a scam? The call ended with my card being canceled and it will be replaced.
However, 2 minutes after I called the number at the back of my card. They (Chase) told me that my card was being replaced with the 2 last transactions being canceled, so it was following the actions of the previous phone call, but the person on the phone was not aware of the 8004549078 number and told me to always use the number at the back of the card.
It looks like disorganization from Chase.
On one hand you get a text message telling you to call a number, and on the other hand the people answering the phone at the number of the back of your card would tell you to always call this[their] number.
No matter what, this is not a scam.
And if you are not a chase customer, and got this message asking you to call this number, it's likely because someone is using your cell phone number ( and maybe your full identity ) to open a Chase account
California May 19th, 2019
I was leery so I called the number on the back of the card, and Chase confirmed that they had been trying to get a hold of me about fraudulent charges. They confirmed the 800-454-9078 number IS legit. They did ask me at the very beginning to enter my card number (automated) and the lady asked me for my mother's maiden name, but not the last 3 digits on the back of the card. Also, my account was already closed when I called (I put in for a new card online 5 minutes before I made the call).
I'm not telling you to call THAT phone number, but call the number on the back of your card. That way you can be sure.
But I'm telling you, it's legit.
OMG how stupid can some of you be? The people use your credit card, are rejected from using it, keep your credit card number and make this call from a sound-alike recording. Then they sweetly tell you that someone used your card and ask you for the 3 numbers on the back of the card and the first letters of your mother's maiden name. I did call to see what they would ask and of course, hung up. Then I called the number on the back of my Chase Card and they told me that number is phony, a criminal operation and they were glad I had the sense to hang up. This morning I had $600 charged on my card (while I was asleep!). Of course, they cancelled my card and reissued me a new one. PLEASE don't ever call a number from someone who you don't believe in real. CHASE told me they are familiar with that number as a scam, criminal operation. And the questions they asked me are what they ask everyone. Noe they can REALLY use your card (because they sure aren't cancelling it...this time they have everything they need for it to work! Disgusting people.
Legit- got txt- called # provided in txt then followed up with call to # on back of card fraud was confirmed.

Rcvd fraud alert call from this number concerning Chase denied charges. Called Chase customer service number on credit card, 800-454-9078 is definitely a good number. 13 attempted charges had been made on our card, glad Chase denied them. Call Chase if you get a message about fraud. Better safe than sorry.

Called Chase, they do not list this number as a legit fraud number for any chase product. Called the phone number, recording says Chase Fraud Dept, and then asks you to enter your card’s last 4. Fake number.
I’ve had 2 calls-different called from #’s & different #’s to call back. They have the wrong name for my cell # and I do not have any credit/banking cards with Chase. I don’t answer calls from #’s I don’t recognize and even looked up #’s for Chase fraud/identity theft who said the number I was directed to cal WAS NOT a Chase #
I work for Chase fraud. This is legit.also to those who don't have a Chase card. It's because someone opend a card in your name.we sadly see it alot.
This is Chase. I also received the text messages asking me to call the number listed. I spoke with an agent who closed my cards and told me I would be sent new ones. I panicked and looked up the number because it didn't show up in my caller ID as Chase Bank, but as soon as I called the website official number I was told that the account had been closed per the phone call I'd made to this number listed.
You are so full of bullshit.
This number 1-800-454-9078 is definitely the correct number for Chase Bank Amazon Visa Cards because they read me back the last five purchases I made correctly and provided me any of with my own information I requested while the woman I spoke to was extremely helpful and professional today. It was an American operator, not some Phillippines number foreign operator as others falsely wrote on this website. If anything is fraudulent it is this website acting in a conspiracy to commit wire fraud by belittling and disparaging the name of Visa Amazon Prime. The employee's of Chame Bank or Amazon that quickly answer calls to this number are doing an important service both by preventing fraud and by helping callers get any fraud inquiry hold on their credit cards lifted promptly.

It was indeed my credit card company trying to notify me of a suspicious $7 charge to the card. I called another of their numbers and cleared the charge.
I would be weary of answering or calling back any number that calls for a credit card, but I would pay attention to the CC's name, so that if you know you have one with that company, you can call them on another line and verify. Had I not done that, my card would have been frozen until cleared. It would have not be pretty to find myself in a shop with a card full of groceries without being able to pay.
This is a legit number for Chase Fraud. After reading some of the answers I called Chase and verified that my card has been deactivated and no longer can be used. Always double check. Anyone saying this is a scam number is wrong. Nice to see they are on top of things for their consumers.
I received several of these Chase msgs. Exactly 15 days apart at the same time of day. I don't have an account. Ridiculous. Phishing. Criminal scum.

Quoting the Californian user:
"Got a text from "Chase" saying... "FREE MSG: Chase Fraud-Did you use card ending 7359 for $197.96 at RENFE VIRTUAL INTERNET on 12/11? If YES reply 1, NO reply 2" I DO NOT HAVE A CHASE ACCOUNT. I pressed 2 just to see what was going on and received this... "FREE MSG: Chase-Thank you. Your card can't be used until we speak with you. Call to turn it on or order a new one. 800-454-9078 or the number on your card."
Pretty weird if you ask me, especially since I do not have a Chase account."
I received a similar message but it turned out to be legit. I'm thinking maybe the person who used to hold your cellphone number had a Chase account?
I'm pretty sure this number (800-454-9078) is legit. I received a similar text message as some of you, asking me to call this number or the number on my card. I didn't call 800-454-9078 because I saw some people here thought it was a scam. However, when I called the number on my card, they immediately told me there was a possible fraud on my card (the same incident reported in the previous text message) without me saying anything about the text.
This # is NOT a scam -- got an email from Chase Bank regarding a fraud charge on my account. You can then call this # or # on back of your card to speak to fraud dept. at Chase. They cancelled my account and will send me a new card tomorrow since there was a fraudulent charge.

This is the Chase Fraud #.
This is the Chase credit card fraud unit. Very helpful staff.
I called the number direct from the Chase / Southwest Visa credit card website to make sure this number was legit - and it was - they had called and left me messages on both my cell and work numbers - please take this number seriously. Someone using a phone number other than the ones listed in my profile called asking information about my card number - not sure how they got that - since they did not recognize the number they followed up with me in case I was calling from a different phone. I say NICE JOB Chase / SouthWest Visa
When in doubt you are never wrong to just call the number on the back of your credit card!!
Pennsylvania Jul 10th, 2017
Definitely fraud.. classless clowns made an answering machine and will try to trick you into entering your full credit card number. Do not fall for this.. For all the posts saying "definitely legit, so disappointing to see so many people report this as fake" ask yourself this.. if the number is legit, why post about it? Unless you are the assclown running the scam trying to reassure people your number is actually real. It's sad.

Seems perfectly legit to me. Annoying so many reporting it as a fraud.
It is the Chase Fraud Department. I got a call from them concerning my brother's card. Because the call came to me, I was concerned that it was trouble so I called the number on the back of MY card and they checked it out for me. It is a legitimate number. I was assured that the reason my phone number was called is that it is listed on my brother's account as an alternate way to contact him.
This is the Chase Fraud Department. Great department. They found several fraudulent purchases on my card. Texted me, emailed me and called. Thankful for their computers that caught the fake charges.
Thanks, all, for your comments; this number just called me and hung up. I blocked the number after reading all your comments. One more a**h*** blocked...
Washington Mar 16th, 2017
This number is legit. I called the number on the back of my card and they confirmed that the Chase Fraud Department had called me.
I received a call this am from this number advising me they were with Chase fraud and asked if I had purchased anything this morning. I had not. They said someone had used my number and they had declined the purchase and they were canceling my card and issuing a new one. I was curious if this was legit so I asked what purchases were ordered. They gave me the information. After hanging up I called the customer
number on my current Chase statement and the rep assured me it was legit and confirmed everything. Before writing off every call is a scam ( I get plenty) double check your statement customer service numbers and be sure. Glad I did.
We received an email about suspicious account activity that looked like it came from Chase. To the untrained eye it would have looked legitimate but I build web applications and could tell by both the look and feel and the subdomain hyperlinks that it was fake and deleted it. A week later my wife gets a voicemail telling her to call this number. I check our account (again mind you, I already did when I got the email) and there is NO activity. Nothing. Nada. Zilch. We have an account but do not use it so this is correct. I called Chase using the number on the back of my card, they confirmed, no activity. So why are we getting a call from this number?
Out of curiosity I went ahead and called. They sound somewhat legitimate on the phone but again, there were little things that I could tell made it fake. I did not provide them any information and they provided me with no information. The person I spoke with had an Indian accent and was personable. They also recommended I call the number on the back of the card.
Amongst the "it's a SCAM" comments and "no it's NOT" comments, I want you to consider one thing. Can something be legitimate when it's validity is repeated called into question? I don't think so. I think you need to verify that your account is in good standing but only by logging into the chase website from typing in the URL your self (never use links in email) or calling the number listed on the back of your credit card.
I've looked up questionable phone numbers before from the site in the first page of Google results. That's how I got here. This is the first I've ever seen where people go back and forth about it being fake or real. That to me is the biggest sign something is wrong. My bet is all the comments saying it is a SCAM are correct and all the other comments (no matter how reasonable they may sound) are actually made by the scammers trying to put on over on you.
Hopefully you see this too...

This is pure fraud. All these posts seeing it is real are part of the scam. One of their questions to me--what was my birthdate because there was a bank error. I DID not give it to them. No credit card would ever ask that question. They already had my email address and the last 4 digits of a card that I had cancelled over a year ago. Luckily they hung up.
Received a text message and phone call about my card possibly being stolen. Upon calling the # on the BACK of my card (different number btw) I was told that indeed fraudulent charges had been made on my card and they would be sending me a new one. Glad they caught it before someone spent way over my credit limit.
This is a legit number for CHASE! When I saw Credit Card Svc on caller ID, I assumed it was another annoying telemarketer. However, it was Chase Fraud Unit and they did leave a message questioning a suspicious charge on our Visa card. They also alerted my husband via email that someone in NJ was trying to buy an RV for $16,000 using our credit card, which we still have in our possession. Good job, Chase! Not a very bright thief to try to charge such a large amount. Hard to say how our card info was stolen. We have not shopped at Target in well over a year, so we can't blame them. Have made a lot of online purchases the past couple of months. Apparently, a conterfeit card was made using our info. So, be alert people! Frequently check your accounts online for unauthorized charges and report them immediately.
This is not CHASE, its fraud. Just confirmed over the phone. do not give your card info!
I just spoke with Chase and this is NOT/NOT their number, this is fraud. Do not give your credit card info!
This is not a legit number for Chase Visa. Chase has no such number, their standard practice for fraud is to always leave a message on the phone number they have on file. I received several calls from this number on Nov 16, 2013. My number is also listed on the National Do Not Call registry.
Robert Doyle Nov 19th, 2013
This is legitimate, apparently. Chase Card Services fraud department. I thought it was suspicious, but I called the # on the back of my card and they repeated the same information.
This is a legitimate call from Visa Chase credit card fraud services. I did not pick up and they left no voicemail. I then got an email from them asking if a suspicious credit card charge was correct. If you get a call from them, go ahead and call the phone number on the back of your card to validate your charge.
Just keeps calling. I do not answer
I had the same thing - 3 calls but no message. When I saw these posts I called the number on my card. It was from the Chase fraud department, verifying a charge that appeared unusual. Thankfully I had actually made the charge they were inquiring about. But they also verified the other charges from the same day to make sure everything was really OK. It's legit!
Yes, a legitimate Chase Fraud call. Contacted customer service and they cleared up a question... not sure why they don't leave a message.
They left a voicemail that they were calling from Chase Fraud. I thought this was a scam, but I called Chase back at the number on the back of my card, and this was indeed a real call.
I called back the number on my card and there was fraudulent activity.
They called but left no message so I called them back, got recording saying Chase Fraud Services. Asked for last 4 #s of my cc. Entered that but then it asked for SSN so I hung up & called # on my Chase cc. SHOCKED to find it was indeed LEGIT. They DID call me. Someone tried to use my account # at a WalMart in Bakersfield for $150 but was declined. There were 2 pending transactions for Target also in Bakersfield. I'm in LA so we know where the criminals are. I have the card in my hand so it was not stolen. Thanks to Chase for their heads-up service.
Dodged fraud Nov 18th, 2012
Left a message on my answering machine; called back after verifying number here. Someone made a fraudulent charge on my Chase Visa and they were verifying it. Closed my account and issued a new card. Legitimate number and service as far as I can tell.
Yeh.. it's Chase. Warning me about a threat to my Chase account. I don't have any Chase acc't and never have. I'll try blocking them.
This number 800-454-**** is looking for somebody else, I have my current number since 2009 and I have 3 days in a rowl that this number is caling. I can stop them because is a maching, so what can I do in this case?
I just received a call from 800.454.9078 and they advised me that they thought my card was being misused. I live in Georgia and they saw charges from New York. They called me to verify that they were not my charges and called me to let me know they could cancel my card and reissue immediately. I have called Chase (number on back of card) and verified that this was a legit card. It never hurts to be careful!!! This is legit. Either way, always call the number on the back of your card.
I called the number they found a fraudulant charge they closed the account then a few minutes later I called the number on the back of my card and they confirmed to me that 800-454-9078 is a legitimate # for chase and assured me that it was chase calling me and that the account had been closed and that they will issue a new card with a new account number all the info for that account is gone from their on line banking I feel that this was all legit they never asked for anythign more than the last 4 of the card they did ask for my last 4of my ss# I have called them 3 times now and they keep telling me the same thing so I feel secure that this was legit
This IS from Chase, who caught an attempted $900 fraud on my Mastercard. Skeptical, I called the # on the back of my card and they asked for the last 4 of my card then reported the attempt.
They called 3 times in hour & a half. We were not home the first 2 times they called, and they did not leave a message. I answered the 3rd call and the computer said it was Chase fraud dept. and gave the last 4 digets of one of my chase cards. Ask if I had made a charge for a dating service in London. NO, so it connected me to live person, who told me 3 other charges had been charged that day, and I told them I had made no charges on that card since last statement. They totaled almost $500 and the largest had been approved and the rest declined.
They cancelled the card and I have to fill out paperwork, stating that I did not make the charges. I have my card, but number was stolen, not sure how, but I guess thay have all different ways.

It's Visa automated Fraud Alert. If you answer it in time it'll ask you if Card '1234' is yours, press '2' to continue. then it reviews your last 3 charges and prompts for '1' or '2' for Yes-Recognized or 2-not recognized. If it's a large amount or overseas charge you'll be sent directly to an agent to verify who you are, if you have your card and if you made the charge. Otherwise, they'll turn your Visa off until you call them. If you have to call back, use the number on the back of your visa.
This is not a scam. If their computerized system sees some unusual activity on your card, the system automatically calls you. The computerized system asks some questions, then, if you didn't make those charges it connects you with a live person. If you did make those charges, the system thanks you, but still gives you the option of talking to a live operator.
My wife recently got one of those calls, and they had, in fact, detected fraud. They were only able to make two charges.
This call concerned me. I did not call the number on my answering machine, but rather the number on the back of my card. The person on the other end jumped right into a sales pitch about a new service they have for $7.95 that will protect me from unwanted charges. I asked several times for her to look at my account to see if there was any strange activity on my account but she just kept saying I'll get you protected, then we can take a look at your account. I did not give authorization to charge my account $7.95 every month, so she finally looked at my account and everything was fine.
Something still didn't sit right with me, so about 20 minutes later I called the number on the card again. I got someone else, who transferred me to Security. The man on the phone said that he needed to look at my account to make sure I was the one making the charges. Right after I said that I had made the charges he mentioned, he went into the same sales pitch for the $7.95 a month protection.
If you get this call, I wouldn't worry about true suspicious activity. I would worry about a card company who is using scare tactics to get their customers to sign up for this monthly expense.
upset in WI Mar 10th, 2010
Chase calling about a possible fradulent charge.
I retired from banking, and when employed, banks, lending business, firms and etc do not do business by phone, if in doubt, call the number on the back of your card.
I do not really know if the number is ligit, but it might serve as an alert to fraud if it is.

It was Chase calling about a fraudulent charge. I called back on the number on my Chase MasterCard and indeed it was a fraudulent charge. If you're concerned that this isn't legit, just call the number on the back of your card.
Absolutely legitimate - Chase's fraud prevention department. Received this call about 20 minutes after I placed an online order from a company I have never before ordered from. As others have advised, it's always best to call the number on the back of your card.
It was chase fraud department. They left a message. So I called the numbe ron my card and was directed to them. Someone was trying to use my card so glad I called!
As surprised as I am, this is indeed a LEGIT call from Chase. I should have known because the message specified it was an Amazon Visa, which it was. I hadn't used the card in over a year, but my website hosting was set to auto-renew (which I didn't know), so they called me to check on this $190.00 charge - I basically had to accept it as (except for the thing being on auto renew) it was a valid charge. Chase closed that account because of the confusion so it couldn't be auto billed again unless I put it back on auto renew on the host site, but the card service itself was fine and a valid call from Chase - I'm actually very pleased with the fraud prevention service, that could have been a real unauthorized charge.
Legitimate call. This is an automated call from the fraud department. They were checking on two purchases that I made on the internet overseas. Chase is just looking out for you. Don't be paranoid...it is the real deal.
Got a phone message saying it was from Chase. A woman's voice...sounded automated. She asked me to call back at: 1-866-204-0047
. I do have business w/ Chase, but I see no reason for someone (automated) to call me.
This call is LEGITIMATE, from Chase Credit Card Fraud Department. The number calls in response to possibly fraudlent charges on a card under their control. If you do not feel safe, or even if you do, end the call and call Chase at their main 1-800 number and get to the fraud department through there.
Caller: Chase Fraud Department
Call type: Service, Legitimate
Legit number, someone was trying to use my card across the country. they did not ask me for any personal information.
It is a legit number from Chase, but call the number on the back of your card for security reasons anyway.
I received an automated message about suspected fraud and a few hours later called the number left in the message, which also the number on my caller ID. After a brief automated system questionnaire regarding two recent charges, I was transfered to an agent. He asked for the 16-digit card number, last four of my social, date of birth, and mother's maiden name. I had just woken up from a nap and being concerned about potential fraud gave this information to the agent without hesitation. He asked again about the two charges which I had not made. He indicated the card would be cancelled and I should receive a new one in 3-5 business days.
Immediately after I hung up I realized I might have just given important information to a scammer! I was very disappointed in myself and anxious about my potential stupidity so I called the number on the back of the card. The agent I spoke with confirmed that the first call was legitimate and the card had been cancelled already.
So, the good news it that it is a legit number and is in fact from Chase fraud services (and I didn't just walk into a scam). However it made me very nervous for a few minutes and reminded me to always be super careful. I guess because I had made the call and it sounded very professional and I was so concerned about the potential fraud I wasn't thinking about what I was doing. It would be an ingenious way to back-door people into giving up info thinking they were protecting themselves. Chase probably should just inform the recipients of the message to call the number on the card, which is what I'll be doing in the future.

It appears to have been Chase. I called the number on the back of the card. They had a record of a call coming to me from the fraud dept although I did not verify the actual number.
They were proactively halting a charge my wife made to buy novelties for our church carnival.
it was legit. I called back on the number on the back of my credit card. they were just verifying a transaction that was large. it was mine.
THIS IS NOT A CHASE PHONE NUMBER!! I JUST CALLED CHASE TO VERIFY THE NUMBER AND WAS TOLD THAT THIS IS NOT ONE OF THEIR NUMBERS! THIS IS A SCAM. THOSE CLAIMING IT IS LEGIT ARE NOTHING MORE THAN INDIVIDUALS FROM THE SCAM POSTING HERE IN HOPES YOU'LL GIVE OUT YOUR INFORMATION. DO NOT DO IT!!
Legit Call. Chase Card Services Fraud section. They detected two charges that turned out to be somebody stealing my CC number. The first charge by the thieves was to Apple ITunes, a small charge to see if it would go through, and then two days later a much larger charge for something else. I was amazed that Chase could tell that the Apple charge wasn't mine (I've ordered some tunes in the past.) However, like others here, I did not call the number back, but checked for Chase's fraud number online and called it. While this is a legit call, don't ever give out personal information to anybody unless you initiated the call (or called back a number you could trust.)
it was a legit call, I called back chase their customer support number, they confirmed the call.
no problem. they suspected some charge on my card was fraud, however, they were not.
This is the number that called me alerting me know that my card was used "out of state" at a gas station while I was cross country :)
