A routing number is a nine-digit number used to identify a U.S. financial institution for certain transfers and payments. Routing numbers may vary by bank, state, account type, transaction type, or merger history.

Where to find a routing number

  • Your bank’s official website or mobile app.
  • Your checks, if you have a checking account.
  • Your monthly statement.
  • Your bank’s customer support.
  • The official Federal Reserve E-Payments Routing Directory.

Use caution

Do not enter bank login details, debit card numbers, or full account numbers into unofficial lookup tools. If a payment is important, confirm the routing number directly with the bank before sending money.

Common mistakes

  • Using a wire routing number for ACH or ACH for wire.
  • Using a routing number from the wrong state.
  • Using an old routing number after a bank merger.
  • Copying a number from an outdated article.
