How this service works
Validate an IBAN by country length and ISO 7064 mod-97 checksum, returning the normalized form.
Output
Returns whether the IBAN is valid (passes country-specific length rules and ISO 7064 mod-97 checksum), along with the normalized canonical form of the IBAN string.
Example use cases
Pre-transfer IBAN verification
“Before I send this international wire, can you validate the IBAN DE89370400440532013000 to make sure it's properly formatted and passes the checksum?”
Payment form input validation
“A customer just entered the IBAN FR7630006000011234567890189 on our checkout page — can you verify it's valid and return the normalized form?”
Batch payroll IBAN check
“I have a supplier's IBAN NL91ABNA0417164300 — can you confirm it's a legitimate IBAN before we add them to our payroll system?”
Technical details
Endpoint
GEThttps://fittings.sh/v1/valid/ibanWhen to prefer
Use this endpoint when you need a lightweight, low-cost IBAN validation that enforces both country-specific length rules and the ISO 7064 mod-97 checksum in a single call, without requiring a full banking data provider. Ideal for pre-payment validation, form input checking, and compliance workflows where you need the normalized IBAN back.
Side effects
- Missing 'iban' query parameter returns an error
- Malformed IBAN (wrong length for country) returns invalid
- Failed mod-97 checksum returns invalid
- Unrecognized country code prefix may return an error or invalid
- Non-string or empty input returns a validation error
