What is the product GTIN code for?
A GTIN identifies a trade item. Use codes actually assigned to your products; do not invent a number to fill a missing field.
In Feed management → Feed data options, select the preferred source. The module processes it as follows:
- EAN: uses an EAN field of 8, 12 or 13 characters, otherwise tries UPC with those lengths.
- UPC: tries UPC first with those lengths, then EAN.
- ISBN: uses an ISBN of 13 characters, otherwise tries EAN of 8, 12 or 13 characters.
These internal length checks validate neither assignment nor the GTIN check digit. They do not validate GTIN-14 codes or define the specifications for all Meta destinations.
Fill in the exported product's or combination's field, regenerate and inspect g:gtin in the XML. The “without EAN/UPC” exclusion is separate from ISBN preference; inspect its diagnostic before assuming that ISBN satisfies that exclusion.
If an item has no GTIN, do not invent one: provide its other real data and consult the applicable Meta specifications. See MPN and brand.
