US Bank Directory & Lookup API

What it does

US Bank Routing Numbers looks up US banks from the Federal Reserve's FedACH (Automated Clearing House) and Fedwire (wire transfer) directories. You send a nine-digit routing number, a bank name or a transfer type, and get back the bank's name, city, state and whether it supports ACH, Wire or both.

USA BANK INFORMATION lists the whole directory, 10,795 institutions, page by page with limit and offset. US Bank Lookup by Routing Number returns one bank for a routing number, and its transfer_type parameter picks the ACH or Wire directory. US Bank Search by Name finds banks by a full or partial name.

US Bank Routing Numbers is a good fit when you need to validate a routing number before a payment, fill in a bank's name and location from a routing number in a payout form, or find the routing number for a named US bank.
