There are two sets of

**nine**digit numbers printed across the bottom of every check. They are followed by a four digit number slightly set off from the others. The first two sets of numbers are your bank routing and checking account numbers; these remain the same from one check to the next.People also ask, can a bank account number be 10 digits?

ABA routing

**numbers**are 9**digits**. There is no well defined standard for the length of US**bank account numbers**. The NACHA standard file format defines the**account number**as up to 17**digits**. In my drawer I have checks from different**banks**with 8**digit**and**10 digit account numbers**.Where do you find your account number?

Your

**account number**(usually 10-12 digits) is specific to your personal**account**. It's the second set of**numbers**printed on the bottom of your checks, just to the right of the**bank**routing**number**. You can also find your**account number**on your monthly statement.
