Routing number FAQ
Can a routing number be validated offline?
Yes — the 9th digit is a checksum over the first 8 digits using the repeating weights 3, 7, 1. The checksum catches most transcription errors.
Do routing numbers differ for wires and ACH?
Yes — many US banks publish separate routing numbers for Fedwire and ACH. Always confirm which rail your payment requires.
