GS1 Digital Link Standard

LinkWrangler supports the GS1 Digital Link standard, which allows product information to be encoded in a web URL.

URL Structure

The URL structure typically follows this pattern, with identifiers and qualifiers in the path, and data attributes in the query string:

https://your-site.com/01/{gtin}/10/{batch}/21/{serial}?17={expiry}

Supported Application Identifiers (AIs)

  • 01 (GTIN): Global Trade Item Number. The primary identifier for the product. Must be exactly 14 digits. Shorter GTINs (GTIN-8, GTIN-12, GTIN-13) are automatically padded with leading zeroes.
