US bank routing instructions

Supported banks and published scope

These pages are built from reviewed first-party bank sources. They supplement the regulator directory; they do not replace it. Unsupported banks are not inferred from similar names.

Turn a routing list into a repeatable review

Try three routing numbers free, review the sources and then request a quote for your full list. Save a baseline and compare it after a source update. Reports distinguish bank-published instructions from rail participation; a change means review is needed, not that a payment will fail.

Existing Pro and Business plans support saved reports and manual comparison. The same list and unchanged source data can be rechecked without lookup credits when synthetic test generation is off. No automatic paid checks or customer messages are enabled.

Why ACH and wire evidence stay separate

A bank may publish different routing instructions by payment type, account-opening region or account history. We preserve those qualifiers instead of collapsing all results into a single “valid” flag. The official webpage can be recently checked without having a published effective date.

No result confirms an account's existence, ownership, balance or payment acceptance. Use synthetic account data in tests. Confirm real payment instructions directly with the bank and recipient.
