Invalid article GTIN

Error:

Invalid article GTIN.

Explanation:

The EAN article code of an article is assigned by the supplier.

It must be a valid GTIN: a worldwide unique coding of articles.

The last number of the code is a verification number, against which the validity is checked.

If this check number is incorrect, this code will appear.

Solution:

Check the incorrect GTINs for validity and correct them. If necessary, ask the producer/supplier for the code.

You can check or request GTINs/GLNs at GS1.
