oops the writers of So Help Me Todd messed up:

"3752… that's an American Express card!"

Nope! There's 0% chance of that being the last 4 of an AMEX! For that to be true, he would have had to had 3 replacement cards and 74 other authorized users.

I always wondered why my AmEx cards ended in 100X... : amex (www.reddit.com)

"37ab-cdefgh-ijklm

All Amex cards start with 37

ab is tied to the country of issuance/market

cd usually relates to the product in the AmEx portfolio

e is billing cycle

fghi is account number

j is the issue number

kl are position on the account, starting with 00 for the main (basic) card holder

m is the Luhn/mod 10 check digit"

Just filed my first credit card dispute. Someone at @parksideaustin changed my $5 tip to $15, good thing I took a picture of my receipt. And thanks to @CapitalOne for sending me an email alert about the unusually high tip!
