Hi, I'm implementing this feature on #1408 and according to my research every US check account number (international is defined by IBAN), has its own system and is kept in private. Usually they can have 10-12 digits but can range from alphanumeric 5-17 and the check number is the same they can be as long as possible is up to the bank, so I guess already exists a defined type for it like UnsignedInt 'cause they are unique sequential issued by the bank.

I'm thinking of leaving check number alone and account number as 5-17 alphanumeric without checksum. Any suggestion ?
