Routing number vs account number: what's the difference?

Banking and credit · 3 min read · Updated

In short: the routing number is a 9-digit number that identifies your bank; the account number identifies your account at that bank. You need both to set up direct deposit or automatic payments. For money coming from abroad, the sender usually also needs your bank's SWIFT code.

Routing number

The routing number, also called the ABA routing transit number, is 9 digits long and tells the payment system which bank or credit union to send money to. It is not secret: many customers share the same one. Some banks use different routing numbers for different states, or one number for direct deposits and another for wire transfers, so check the right one for what you are doing.

Account number

Your account number identifies your own checking or savings account. It is usually 8 to 12 digits, but lengths vary. Treat it as private: together with the routing number, it can be used to take money out of your account by electronic transfer or a fake check.

Where to find them

Get the numbers from your bank directly, not from a search result: a wrong digit can send money to the wrong place, and it can be hard to get back.

SWIFT codes and IBANs

A SWIFT code (also called a BIC) is 8 or 11 letters and numbers that identifies a bank for international transfers. US banks don't use IBANs, which are common in Europe and some other countries; a US bank account is identified by the routing number and account number instead. If someone abroad asks for an IBAN to pay you, ask your bank what details to give.
