    I am surprised that they don’t provide UUIDv4’s, feels like what they provide is somewhat guessable

          Nowadays, not so much. In the previous decades before password managers, card vaulting, apple pay and so on: yes, if you were typing it in or writing it on forms frequently, it wasn’t uncommon to just memorize it.

          My point though was that there is a limit to our ability to remember long and random alphanumeric strings, and I find credit card numbers to be that limit. UUIDs are longer and have a much bigger character set.
