A US routing number is a 9-digit code used to identify a bank in the United States.
It ensures that funds are sent to the correct bank when processing transfers.
A routing number may also be called:
• ABA routing number
• Routing transit number
• ACH or wire routing number
When is it required?
A routing number may be required when sending money to a bank account in the United States, depending on the transfer type.
Tip: Some banks use different routing numbers for different types of transfers (e.g. ACH vs wire), so it’s best to confirm the correct one with your receiver or their bank before sending.
