Variants now support multiple barcodes
Shopify developer change
MerchantDiff detected this entry in Shopify's official developer changelog on September 08, 2026.
This Shopify update is categorized as Action Required, API, Deprecation announcement, GraphQL Admin API, 2026-10.
What changed
Merchants often sell the same variant under more than one identifier: a manufacturer UPC alongside a private-label EAN, a GTIN, a reissued ISBN, or an ASIN for a marketplace listing. Until now a variant held a single barcode value, so the extras ended up in metafields, tags, or outside Shopify entirely. What's new You can now read a variant's full set from the new barcodes connection on ProductVariant, and write it with the barcodes input on the productSet mutation, productVariantsBulkCreate mutation, and productVariantsBulkUpdate mutation. Each barcode can declare a type: UPC, EAN, ISBN, GTIN, or ASIN. We validate the value against that standard's character, length, prefix, and check-digit rules.
