About RoutingRadar — Independent US Routing Number Directory

RoutingRadar is an independent reference site that helps US bank customers, payroll administrators, and small-business owners verify ABA routing numbers before initiating ACH payments, wire transfers, or direct deposits. We currently track 18,198 routing numbers across 10,266 banks and credit unions in 56 US states and territories.

How we source our data

Every routing number on this site comes from the Federal Reserve FedACH Participant Directory — the canonical, authoritative file maintained by the Federal Reserve as part of its operational responsibility for the US Automated Clearing House network. The Fed publishes the directory in fixed-width text format under an open agreement at frbservices.org, and the file is the same one that banks themselves consult to validate routing numbers before originating ACH transactions.

We mirror a recent build of that file, parse it into a structured database, normalize the bank names so that branches roll up to a common parent institution, and publish each entry as a clean web page. We do not invent records, scrape user-submitted data, or accept paid placement. If a routing number is not in the FedACH directory, it does not appear here.

Editorial principles

Authoritative source first. The Federal Reserve's FedACH directory is the only data source used to populate routing numbers on this site. We treat the Fed's record as canonical, even when it conflicts with marketing material on a bank's own website.
No paid placement. No bank, credit union, or third party can pay to be featured, demoted, or removed from RoutingRadar. The "featured banks" lists you see on the homepage are sorted strictly by branch count.
Plain English over jargon. Routing numbers and the payment networks they sit on are obscure topics, and the existing reference material online tends to be either marketing-flavored or written by payments-industry professionals for other professionals. Our guides aim to fill the gap with explanations a non-specialist can actually use.
"Verify with your bank" — every time. Even with an authoritative data source, routing numbers can change after a merger, an acquisition, or a network reorganization. For any high-value or time-sensitive payment, we recommend confirming the routing number directly with your bank by phone before initiating the transfer.

What RoutingRadar is not

We are not a bank, a payments service, or a financial advisor. We do not move money, hold customer accounts, or process transactions of any kind. We do not provide legal, tax, or financial advice. We are an editorial reference site — comparable to an online encyclopedia entry for a routing number rather than a tool for executing a payment.

If you are involved in a wire-fraud incident, a misrouted ACH payment, or any other dispute with your bank, please contact your bank directly and, where appropriate, file a complaint with the Consumer Financial Protection Bureau or report fraud to the FBI Internet Crime Complaint Center. RoutingRadar cannot intervene in active payment disputes.

Corrections and feedback

If you spot a routing number record that appears to be inaccurate, out of date, or missing, please get in touch through our contact page. We refresh the underlying FedACH file periodically, and we publish corrections as soon as we can verify them against the source.
