Find your GTIN errors before a retailer does.
GTIN Validator Kit: $149, one payment
The kit checks every GTIN in your product file against GS1 rules and six retailer checklists. It shows each problem row by row, with the fix, and gives you a corrected file. It runs in your web browser on your own computer, so your product data never leaves it.

What you get
- Every issue, row by row, with the fix: check digits, lengths, duplicates, company prefixes, and case-to-unit relationships.
- A corrected GTIN file to paste back into your product master or retailer portal.
- Checklists for Walmart, Costco, UNFI, Whole Foods, KeHE, and 1WorldSync, listing the GTINs that fail each one.
- A readiness score and a PDF report for your team or broker.
- A cost-of-inaction estimate, with assumptions you can edit to match your retailers.
How it works
- Buy the kit. Payhip emails you a download link right away.
- Save GTIN-Validator-Kit.html anywhere on your computer and double-click it. It opens in your web browser.
- Choose your CSV or Excel file, or paste your GTINs. The kit finds your GTIN column; change it if it picked the wrong one.
- Read the results on screen, then download the CSV report, the corrected GTINs, and the PDF.
No account, no install, and no internet connection needed once it’s downloaded.
What it checks, and what it doesn’t
It checks format and structure: whether each GTIN is a valid GS1 number, whether it’s duplicated, whether your company prefixes and case-to-unit relationships are consistent, and whether it meets each retailer’s GTIN rules.
It doesn’t look your GTINs up in GS1’s registry or a retailer’s database, so it can’t tell you whether a GTIN is assigned to the right product. It checks your data before you submit it.
