What are routing numbers?

An ABA routing transit number (RTN) is a nine-digit code that identifies a US financial institution. Banks use different routing numbers for:

• ACH transfers — Direct deposits, bill payments, and electronic transfers between banks
• Wire transfers — Domestic wire transfers (often a different number than ACH)
• Regional branches — Many large banks have different routing numbers by state or region

The type field indicates whether each number is used for ACH transfers, wire transfers, or both.
