GS1 Digital Link

GS1 Digital Link is a GS1 standard for expressing identifiers such as a GTIN inside a web address, in a form like /01/ followed by the number. A resolver at that address sends the request to the right page for that item, so the barcode itself becomes a link.

How it differs from a product URL

A product URL is chosen by a site and differs between sellers. A Digital Link path is built from the GTIN by a published rule, so anyone holding the barcode can construct it.

Example

Our resolver at /01/{gtin} returns the canonical record for a GTIN we publish, and a 404 — not a guess — for one we do not.
