IBAN Validator with Structure and Check-Digit Verification

API ↗

IBAN Validator with Structure and Check-Digit Verification is a paid API for AI agents from api.ozdreamtools.de, paid per call via x402, $0.02/call, status unknown (last checked 2026-10-10).

Validates an IBAN by checking country prefix, length, segment structure against the SWIFT registry, and verifying or recomputing ISO 7064 MOD 97-10 check digits — reporting every check with pass/fail status.

How this service works

Validates an IBAN: country prefix, length, segment-by-segment structure and the ISO 7064 MOD 97-10 check digits, recomputing the correct ones when they are wrong. Checked against the SWIFT IBAN Registry, which also yields bank and branch identifiers and names territories sharing a prefix (Jersey uses GB). Reports every check with status, not only failures, and states what it does not check: existence, bank name, national BBAN check digits. No outbound request.

Output

A structured report listing every validation check (country prefix recognition, length conformance, segment-by-segment structure, MOD 97-10 check digit verification) with individual pass/fail statuses, the bank and branch identifiers extracted from the BBAN, notes on territories sharing a prefix (e.g. Jersey uses GB), the correct check digits if the supplied ones were wrong, and an explicit statement of what was NOT checked (account existence, bank name, national BBAN check digits).
