How to use this tool

Paste a full IBAN, including the country code and check digits.
Confirm the checksum passes and note which domestic components were extracted.
Use the linked directories to enrich bank metadata or to validate branch status before payouts.

Compliance use cases

Screen counterparties by matching IBAN bank codes against sanctioned institutions.
Automate document requests when the branch code maps to higher-risk geographies.
Trigger alerts when customers provide IBANs for unsupported countries or failing checksums.

Data quality tips

Spaces and hyphens are removed automatically—store IBANs as continuous characters.
Always validate against the latest ISO 13616 registry for new country formats.
For countries without published directories, request bank letters to confirm ownership.

FAQ

Why does my IBAN show unknown components?: The decoder currently covers the most common SEPA formats. Future updates will add more countries and proprietary mappings.
Does a valid checksum guarantee the account exists?: No. The checksum proves structural integrity only. Work with the beneficiary or bank to confirm account ownership.
Can I bulk decode IBANs?: Use the ToolHop API proxy or export this component into your internal onboarding tooling for batch operations.
