How IBAN Decoding Works

Every IBAN follows ISO 13616. BIC/SWIFT is resolved via live registries with a built-in bank database fallback for comprehensive coverage.

01 — COUNTRY CODE

2-Letter ISO Code

The first two characters identify the country using ISO 3166-1 alpha-2 codes (e.g. IT, GB, DE, BE, FR).

02 — CHECK DIGITS

MOD-97 Validation

Characters 3–4 are check digits computed via MOD-97. A valid IBAN always produces a remainder of exactly 1.

03 — BIC / SWIFT

Registry + Built-in DB

BIC is resolved via parallel live registry lookups, with a built-in bank database covering all major banks worldwide as a guaranteed fallback.

04 — BBAN

Bank Account Data

The BBAN encodes bank code, branch code and account number — the exact fields vary by country.
