Account Number

You have your own account number. It's called your social security number, and all kidding aside, in 1954, a bill was sent to Congress requiring every American to have their SSN tattooed on their body. It didn't pass. Thank goodness for the Jewish lobby on that one.

As far as financial accounts go, with almost eight billion people on this planet and three billion who save money in some form, names alone are no longer enough to give everyone their own unique account number. Luckily, the number lines banks control go well past eight billion.
