ABA Routing Number Lookup

What is a routing number?
A routing number is a 9-digit code that identifies a U.S. bank or credit union. Also called an ABA number or routing transit number (RTN), it directs ACH transfers, domestic wire payments, and check processing to the right institution and location. Always use the correct routing number to avoid delayed transfers.
Routing number format
Every U.S. routing number (ABA/RTN) is 9 digits long:
Region / Federal district (AAAA): Identifies the Federal district and processing area for your bank.
ABA institution identifier (BBBB): Identifies your specific bank in that district, like a bank ID.
Check digit (C): A final “math check” digit that helps catch typos or wrong entries.
Example of a routing number
Where is the routing number on a check?
You can find your routing number at the bottom left of your check. It’s the first nine digits in the row of numbers at the bottom, followed by your account number and then the check number.

Choosing the right routing number
Banks often use different routing numbers for ACH, wires, and checks. The number printed on your checks may not be the one you need for an ACH transfer or direct debit. If you’re unsure, confirm with your bank or use our routing number lookup to find the right number. Using the wrong number can cause delays or returns.
Routing number vs account number
These numbers work together but do different jobs. Your routing number is a 9-digit code that identifies your bank and routes ACH payments, domestic wires, and checks. Your account number is an 8-12 digit code for your individual account. You’ll find both on a paper check—the routing number comes first at the bottom left, followed by the account number.

A routing number, also called an ABA number or routing transit number, is a 9-digit code that identifies a U.S. bank or credit union for ACH transfers, domestic wire transfers, and check processing. It works with your account number to make sure money is sent to the right bank and the right account. Routing numbers are used only for U.S. payments.
Use the ACH routing number for direct deposit, payroll, and automatic bill pay. Use the wire routing number for domestic wire transfers.

No. Routing numbers are for U.S. payments only. For international transfers you will usually need the recipient bank’s SWIFT or BIC code and, in many countries, an IBAN or local account format. If you need to send money abroad, compare your options and use Xe to see the total price upfront, get a clear delivery estimate, and track your transfer.
Large banks often have different routing numbers by state, by payment type, or because of mergers. Choose the number that matches your account and payment type. If your bank notifies you of a change, update direct deposits, payroll, and bill payments to avoid delays or returns. When in doubt, verify in online banking or with our routing number lookup.
