Seems to be a scam. I got a call from this number on my cell. On the other side a synthesized voice system stated to be calling from First Northern Credit Union and that there are technical difficulties with my debit card. I was prompted to enter the card's 16 digit number. This is the first time I hear about First Northern Credit Union so I don't have a card with them either. I tried some random card numbers but I could not get past the card verification and the system kept asking me for the card number.
