How it works
What does this tool checkexactement ?
Mathematical validation
We check that the 13th digit (check digit) matches the sum of the first 12 digits using the Modulo 10 algorithm specified in the GS1 standard.
GS1 country prefix
The first three digits indicate the GS1 organisation that allocated the code range. This is a historical convention — this prefix does not indicate the country of manufacture.
EAN Express Public Register
If the code was issued by EAN Express and the owner has published it (GDPR consent), the brand, product and reference number are displayed.
Limitations of public audit
There is no publicly available global database of assigned EANs. GS1 does not make its private register available via a free API. A “structurally valid” code may well already be in use elsewhere without any tool being able to detect it. Only codes issued by EAN Express (or other resellers) can be verified in their respective registers.
