# Bank Code Lookup

> Index of UK and US bank identifiers read from the banks' own published pages: 14 banks, sort codes, SWIFT/BIC codes, IBAN formats and ABA routing numbers, each quoted verbatim with its source URL and retrieval date. No licensed directory is republished here.

## Key facts
- Every code in the index was read on the bank's own website, quoted word for word, with the source URL and the date it was read (as of 2026-09-11T00:00:00Z).
- A bank that does not publish an identifier openly is recorded as not published, never guessed or filled in from a third-party directory.
- Coverage is the United Kingdom and the United States only; identifiers for other countries are out of scope rather than partly served.
- Nothing here is a rating: list ordering is a printed rule (verified identifier count, then name).
