Where to find your routing number

Three ways to find the nine-digit code you need for ACH transfers, direct deposits, and wire transfers.

1

On your check

The routing number is the first 9 digits printed at the bottom-left of any check, before the account number.

2

In your banking app

Open your bank's app and look under account details or settings — most banks display it there.

3

On your bank's website

Search "[bank name] routing number" — banks publish them on their support pages, often by state.

Bottom of your check

021000021Routing #
000123456789Account #
1001Check #

Always the first 9 digits, read left to right.

How routing numbers work

Every ABA routing number follows a precise 9-digit structure defined by the American Bankers Association.

1–2

Fed District

Identifies one of the 12 Federal Reserve Bank districts that processes transactions for this bank.

3–4

Processing Center

Narrows to the specific Federal Reserve office within the district.

5–8

Bank Identifier

Uniquely identifies the financial institution within its Fed district.

9

Check Digit

A modulus-10 checksum that catches typos and transposition errors.
