IBAN Component Decoder

Decode IBANs by country to expose bank codes, branch identifiers, and account numbers. Validate MOD 97-10 checksums and link directly to national bank directories for enrichment.

How to use this tool

  1. Paste an IBAN and let the tool normalize separators automatically.
  2. Verify checksum validity and inspect country-specific segment extraction.
  3. Export decoded JSON or follow linked registries for deeper enrichment.

Compliance use cases

  • Support onboarding checks with country-level banking component visibility.
  • Flag unsupported formats or failed checksums before payout submission.
  • Cross-reference decoded bank identifiers against regulatory sources.

Data quality tips

  • Persist IBANs in normalized form without spaces or punctuation.
  • Checksum validity confirms structure, not account ownership.
  • Keep country format mappings updated with ISO and national changes.

FAQ

Why can a valid IBAN still fail downstream checks?
Checksum success validates structure only; providers may enforce additional ownership and network rules.
What if my country is not decoded yet?
Unsupported country formats can be added by extending the country segment mapping.
Can I use this for bulk processing?
The UI is single-entry, but JSON output can be integrated into broader internal workflows.
