What if it is not an IBAN?

valid: false as a 200. iban still echoes the cleaned-up value. Same as a typo in a form field.

What are bank and branch?

bank is the code parsed from the number. Optional deep adds branch and account decomposition plus checksum digits, included on every plan. bank_name and bic stay in core and are null when unknown or ambiguous.

Which countries have bank names and BICs?

The directory table above shows bank-name and BIC fields by country, with notes for individual banks. Gibraltar covers Xapo. Each field comes from a matching bank record. A missing or ambiguous match returns null without changing the checksum result.

Can I skip the country prefix?

Pass country= and we fill it. A prefix already on the value wins.

Does this prove the account exists?

No. Structure, ISO checksum, the national BBAN check when published, and the issuing bank from the directory. Whether the account is open is a name check at the bank, a different product.

Is the country in SEPA?

GET /bloc/sepa/countries lists the members on every plan. Paid country detail also includes deep.blocs.

Fine. Spaces and punctuation are stripped. The response iban is uppercase with no spaces. formatted carries the print form in groups of four for display.
