How this service works
Checksummed-identifier-format generator API. Generates a structurally valid isbn, upc, vin, or imei, each computed with its real check-digit algorithm. vin and imei take no arguments. Accepts optional locale (default en_US).
Output
Returns a structurally valid, checksummed identifier string for the requested format (ISBN, UPC, VIN, or IMEI), computed using each format's authentic check-digit algorithm. The generated value passes real validation checks for its respective format.
Example use cases
Test data seeding for e-commerce
“I need a valid UPC barcode number with a correct check digit to seed my test product database — can you generate one?”
Automotive software testing
“Generate a valid VIN number for me to use in my vehicle management system's test suite.”
Mobile device registry testing
“I need a structurally valid IMEI number with a real check digit for testing my device registration API — can you create one?”
Technical details
Endpoint
POSThttps://ppu43fkyhimq5fiqpmo42eh5ri0yypid.lambda-url.us-east-1.on.aws/generateChecksumFormat?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need test or dummy identifiers that are structurally valid and pass checksum validation — not just random numbers. Ideal for seeding test databases, mocking APIs, or generating realistic sample data. Unlike random number generators, this endpoint applies the real check-digit algorithm so the output passes format validation.
Side effects
- Invalid field value (not isbn/upc/vin/imei) returns an error
- Passing args to vin or imei (which accept no arguments) may return an error
- Invalid locale format may produce unexpected results
- Network timeout from Lambda cold start
