How this service works
Validate a GTIN-8/12/13/14, UPC-A or EAN-13: check digit, format, GTIN-14 normalization, packaging indicator.
Output
Returns a validation result for the submitted GTIN/UPC/EAN code, including whether the check digit is correct, whether the format matches the expected GTIN variant (8/12/13/14), the GTIN-14 normalized representation, and the packaging indicator value. Invalid codes return structured error details indicating what failed.
Example use cases
E-commerce product catalog validation
“Before I bulk-import these 500 products, can you validate this sample GTIN-13 barcode 0614141999996 and tell me if the check digit and format are correct?”
Retail receiving quality check
“We just received a shipment with a GTIN-14 code 10614141000415 on the outer case — can you verify that barcode is properly formatted and tell me its packaging indicator?”
Supplier barcode compliance audit
“Our supplier sent us a UPC-A code 012345678905 — can you validate it and confirm the check digit is correct so we know it's GS1-compliant?”
Technical details
Endpoint
GEThttps://trade.chainverdict.xyz/v1/gtin/validateWhen to prefer
Choose this endpoint when you need to programmatically verify GS1 barcode codes (GTIN-8, UPC-A/GTIN-12, EAN-13/GTIN-13, GTIN-14) for correctness before product catalog ingestion, supplier onboarding, or retail compliance checks. It also provides GTIN-14 normalization and packaging indicator parsing, making it suitable for supply chain and logistics workflows that require more than a simple check-digit calculation.
Side effects
- Missing or empty 'code' query parameter returns a 400 error
- Non-numeric or malformed barcode string returns a format validation failure
- Incorrect check digit returns a check digit mismatch error
- Code length not matching any GTIN variant (8/12/13/14) returns a length error
- Network timeout or service unavailability returns a 5xx error
