How this service works
Check a BIC (SWIFT code) against the ISO 9362 structure: institution code, a real country code with its name, location code, branch code, whether it is the head office (XXX or 8 characters), a test BIC or a passive participant, and the 11-character form. Computed locally; it checks the format and country, not whether the bank exists. Use before an international transfer or to clean payment data; for account numbers use validate_iban.
Output
Returns a JSON object with the original input, normalized 11-character BIC, a validity boolean, institution code (4 chars), country code and full country name, location code, branch code, and boolean flags for head office (branch XXX or 8-char BIC), test BIC (location code passive indicator), and passive participant status. If invalid, a note field explains the structural error.
Example use cases
Pre-transfer BIC verification
“Before I send this international wire, can you validate the SWIFT code CHASUS33 and tell me if it's a valid format, what country it's for, and whether it's the head office?”
Payment data cleanup pipeline
“I have a list of BIC codes from our customer database and I need to start with BNPAFRPP — can you validate its structure and extract the institution code, country, and branch so I can clean our payment records?”
Detect test or passive BIC codes
“Can you check the BIC MARKDEF1XXX and let me know if it's a real head office code, a test BIC, or flagged as a passive participant?”
Technical details
Endpoint
GEThttps://agent-data-tools.revmesh2074.workers.dev/bic/validate?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need fast, local format validation of a BIC/SWIFT code before an international payment, or to parse and clean BIC data in bulk. It is ideal for pre-flight checks on payment forms, ETL pipelines cleaning financial records, or any workflow where you need to extract structured components (institution, country, branch) from a BIC. It does not confirm bank existence — if you need live registry lookup, use a separate SWIFT directory service. For IBAN validation, use the companion validate_iban endpoint instead.
Side effects
- BIC shorter than 8 or longer than 11 characters returns valid=false with a note
- Invalid or unrecognized country code (positions 5-6) returns valid=false
- Non-alphabetic characters in institution or location code return valid=false
- Empty or missing bic parameter causes a 400 error
- Does not verify whether the bank actually exists in SWIFT directories — only format and country are checked
