Yes, confirmed today 12/1/2009 that 800-592-1160, 866-231-9049 and 623-492-6031 are all American Express numbers -- genuine. Some are unlisted numbers but they are all part of AmEx. It's not totally clear why they have hidden numbers or why they are calling people asking for SS# and card numbers. AmEx clearly states on their web site that they never call and ask for your full numbers -- but that is exactly what they are doing. I just spent several hours with them on the phone today talking to their fraud department, because at first I suspected this was a scammer. But these are all originating from AmEx. Even more bizarre is that the fraud dept kept asking for my SS# also (even though I don't even have an account with them). Obviously I didnt' give it (never give this out). They call me from this number all day and night.

The bad news is that they seem to be robocalling everyone in the U.S. -- maybe trying to sign them up for AmEx (motivation not clear). Very annoying because they keep calling even though I'm on the do not call list and have asked repeatedly not to be called. They call on average every few hours for the past few weeks.

The good news is that you can easily sue them for $500 per call. I'm doing this right now, and will post my results when done -- but others have done this successfully. It's very easy and cheap to do. In NY, just stop by the courthouse, fill out a very simple 1 page form, and pay $20. Since they called me 7 times in the past 48 hours, I'm suing for $3500 + the $20 court fee.

Robo-calls to a home phone number is illegal (except for charities and political campaigns). So if AmEx called you and you didn't ask them to -- you're entitled to $500 per call. It's an easy way to make money and also tell Amex not to bother you again. When you fill out your small claims paperwork -- just mention they are violating the Federal Telephone Consumer Protection Act (TCPA) -- which clearly states that automated calls are illegal. If you are on the Do Not Call registry, or have asked them to stop calling you in the past, you may even be entitled to more money.

This only takes a few minutes, and is easy to do -- so please give it a try. If Amex has annoyed you with their repeated robo-calls, this is a great way to get some justice -- and some extra money. Best of luck!

This is definately a scam. I called Amex w/member # on my card. They did not recognize this number and my acct had no problems. I called back the scam # and they said I would have to give them my acct # before they can help me. Not in this lifetime!

They claim to be American Express. HIGHLY SUSPICIOUS! Do not call. Use the toll-free number on your card to call AmEx directly.

I have had enough of these people. Not only do I NOT have an American Express card, I don't want one, either. I decided to call them back this morning. The recording says "thank you for calling American Express" and then informs you that the call might be monitored. It then prompts you to enter your 15 digit account number. Since I don't have one, I made one up...234-567-89123456. It didn't like that ("unable to recognize") so I made up another one that started with 4788 (a common prefix for VISA cards) and guess what! I got through to "Mr. Wesley."
Mr. Wesley thanked me for calling and once again requested my account number. (That would be the account number that I don't have and never HAVE had.)
I find it interesting that a VISA prefix gets you to a real person.
If anyone out there has an American Express card, without divulging personal data...does your account start with 4788?
This stinks to high heaven. I would like to go see "Mr. Wesley" personally.

got call in DC from this #

Origianl call claimed not to be telemarketing service yet advised I should have my acct # ready when I return their call. Yeah right! The 1st thing asked for by the VM system is you acct #. The live person will not respond without your acct #. My advice -- NEVER give your acct. # in response to an unsolicited call. If it is AMEX, they should have named me on the call. Or, the operators on the call desk should know the subject of the type of calls they receive in response to the original calls. Do not trust this at all!

When called, there is a recording that says it's American Express ... but it does not use the same exact series of questions that American Express uses. When I used a different # to call AE, they could not identify this #.
