Regular Expression for Bank Account Number?
regex
Solution
The US doesn't conform to IBAN standards for account numbers; AFAIK there is no definitive US standard for account numbers, just for routing numbers.
Problem
I need to write a regular expression to check for valid bank account number format of major banks in USA and Canada (I already know the format for transit number and institution number, but I don't know the format for account number). Does anyone know what regular expression check should be? Perhaps I just check to make sure all characters are digits?
