Routing Number Lookup

What is a Routing Number?

A routing number (also called an ABA routing number or routing transit number) is a 9-digit code that identifies a financial institution in the United States. Banks use routing numbers to process wire transfers, direct deposits, bill payments, and other electronic transactions. Each bank has at least one routing number, and large banks may have different routing numbers for different regions.

Where to find it: Look at the bottom of any check — the routing number is the first 9 digits on the left, before your account number.
