See here for full reference on how it works:

See here for a list of issuers:

The first link only list the card numbers first two digits which are 34 & 37, which indicates it's an Amex, common knowledge, but thanks!
The second link is the reason I started this thread, it is missing all the numbers which are non 37 and is incomplete, such as the one's with 34's and all current 37's, the list is outdated.
Card's such as the Centurion, Costco Amex, and possibly recently issued cards are not listed as well.
Thank you for your contribution.
