About EAN Check
Verify EAN-13, EAN-8, and UPC-A barcodes with checksums and GS1 country decode.
Enter 8, 12, or 13 digits (UPC-A is zero-padded to EAN-13 internally). The alternating 1-3 weighted sum must land on a multiple of 10, and the leading digits decode to the GS1 issuing country via the built-in prefix table.
A pass proves structure, not registration — anyone can print a valid-looking code. Real product identity needs the brand owner’s database. Everything runs in your browser.

Frequently Asked Questions
- Does the country mean made there?
- No — it names the GS1 member organization that issued the prefix, often the brand’s home country, not the factory.
- EAN-13 vs UPC-A?
- UPC-A is 12 digits, the North American sibling. Prefix a zero and the same checksum math applies.
- Can two products share a code?
- Legitimately, no — prefixes are licensed per company. Duplicates signal counterfeits or data-entry errors.
