What the checker tests.

Length and format

GTIN-8, GTIN-12 (UPC-A), GTIN-13 (EAN-13) and GTIN-14. Spaces and dashes are ignored.

Check digit

The last digit is calculated from the others. A typo almost always breaks it.

GS1 prefix

The first digits show which GS1 organization issued the number. It is not the country of origin.

    A valid code is not yet the right code.

    A correct check digit only proves the number is well formed. Central checks that each code belongs to your product, against the brand and specialist retailers, for your whole catalog.

    Instead of finding out from a channel rejection that a code belongs to another product.

What is the difference between EAN and GTIN?

EAN-13 is one GTIN format. GTIN is the family name: GTIN-8, GTIN-12 (UPC-A), GTIN-13 (EAN-13) and GTIN-14.

Does the prefix tell me where a product was made?

No. The prefix shows which GS1 organization issued the number, not where the product was made.

Is my data sent anywhere?

No. The checker runs entirely in your browser.
