Verify any US bank
routing number in seconds.

Why a dedicated routing number directory?

Every electronic dollar that moves between US banks rides on a nine-digit identifier called a routing transit number, or RTN. The American Bankers Association (ABA) introduced the system in 1910 to standardize check clearing, and a century later it is still the backbone of US payments — used by ACH transfers, domestic wires, direct deposits, e-checks, and bill-pay services. Use the wrong number and your money can land in another institution, sit in a suspense account for days, or bounce back with a fee attached.

RoutingRadar exists because the official source for that information — the Federal Reserve's FedACH Participant Directory — is a flat, fixed-width text file that's effectively unreadable to anyone outside a bank's operations team. We parse the same authoritative data feed, normalize the bank names, group thousands of branches under their parent institutions, and publish each entry as a clean web page you can actually scan. Reference shoppers also find our cross-listed payment-tool comparisons useful when they need to choose between an ACH push, a same-day wire, and a card rail.

What you can do here

• Look up a routing number — paste any nine-digit number into the search box to instantly see which institution owns it, where its primary FedACH-registered office is located, and which Federal Reserve district handles its settlement.
• Find your bank's routing number — search by bank name to see every routing number that institution publishes, broken out by state. National banks like JPMorgan Chase, Bank of America, and Wells Fargo each maintain dozens of state-specific RTNs.
• Browse by state, city, FRB district, or bank type — list every bank and credit union with a FedACH-registered address in any US state, every credit union nationwide, every national bank in California, and so on.
• Read the guides — clear, plain-English explanations of how routing numbers behave differently for wires, ACH credits, direct deposits, international SWIFT transfers, and paper checks.

Where the data comes from

Our underlying record set is sourced from the Federal Reserve's FedACH Participant Directory, the same file that banks themselves consult to validate ABA numbers before sending an entry into the ACH network. The Federal Reserve publishes that file under an open agreement at frbservices.org; we mirror a recent build and refresh it periodically. Each entry preserves the original bank name, registered street address, city, state, ZIP code, and the customer service phone number on file with the Fed.

RoutingRadar does not invent records, scrape user-submitted data, or accept paid placement on its data pages. If a routing number doesn't appear here, it probably isn't currently active in the FedACH network — which usually means it's been retired, replaced through a merger, or is reserved for a credit union shared-branching network rather than direct ACH origination.

Always confirm a routing number directly with your bank before initiating a large or time-sensitive transfer. Routing numbers can change after a merger, an acquisition, or a network reorganization, and a number that was correct last year may now route to a successor institution.
