What does the GTIN Batch Validator do?

It validates barcode numbers (GTINs, UPCs, EANs) by checking the mathematical check digit, detecting the barcode format, finding duplicates, and looking up the GS1 country of origin prefix. It processes thousands of barcodes at once.

What barcode formats are supported?

The tool validates GTIN-8 (EAN-8), GTIN-12 (UPC-A), GTIN-13 (EAN-13), and GTIN-14 formats. It auto-detects the format based on the number of digits and validates the check digit accordingly.

Is my barcode data kept private?

Yes. All validation runs entirely in your browser. Your barcode numbers are never sent to any server. The GS1 country prefix lookup uses a local database bundled with the tool.

How many barcodes can I validate at once?

You can paste or upload up to 100,000 barcodes at once. The tool processes them in batches for performance and displays results in a paginated, sortable table.

Can I export only the valid or invalid barcodes?

Yes. You can filter results by status (valid, invalid, or duplicate) and download the filtered list as a CSV. This makes it easy to isolate problem barcodes for correction.
