Walmart seller glossary
EAN (European Article Number)
13-digit GTIN format — the standard barcode shape outside North America.
EAN-13 is the 13-digit form. EAN-8 is the compressed form. Walmart accepts both via productIdType=EAN in the MP_ITEM feed.
When in doubt, store the 14-digit GTIN form (zero-padded EAN-13) for cross-marketplace compatibility.
