What is a routing number?

A routing number is a 9-digit code (the ABA routing transit number) that identifies your bank on a US transfer. It's the first set of digits on the bottom-left of a check. The number you use can differ by purpose — one for direct deposit and ACH, another for domestic wires — so match it to the transfer and confirm it with your bank before sending money.
