r/CreditCards on Reddit: I need help figuring out which bank issued me a MasterCard
August 14, 2023 -
I feel dumb asking this but anyway... I ordered food through a delivery service last night where I had saved two credit cards in the past. One card in the app was expired so I ordered with the card that is still good. I thought I recognized the last 4 so I placed the order but went looking for the card to make sure I had setup autopay on the account but I can't find a card with the same last 4 digits in my house. All I know is that it's a Mastercard, the last 4 digits and the expiration date. I tried calling the app support but they only see that it's a Mastercard. I don't think it's one of those gift cards because the account it's tied to allowed me to get free delivery so I'm pretty sure it was issued by a major bank in the US. I downloaded my credit report from all 3 credit bureaus and I can't find an account with those last 4 digits. So yeah I feel silly but uuuuuhh, how do I find out who issued this card to me lol
