GS1 Digital Link

Listrar summary

GS1 Digital Link is not a regulation — it is the standard that makes product identity resolvable. It encodes a product's GTIN into an ordinary web address: https://…/01/09506000134352 names the same product for a checkout scanner, a browser and an AI agent, and one scan can lead to the passport page, the manual or the recall notice. The EU's DPP texts require identifiers that resolve; GS1 Digital Link is the de-facto way the industry answers, and it is why every Listrar product resolves under /01/{gtin}.

Who does it apply to?

• Brands that already own GTINs — the barcode numbers they print today
• Retailers preparing checkout scanners for QR codes (GS1's 'Sunrise 2027' ambition)
• Marketplaces and data pools that need one canonical identity per product
• Registries and resolvers — Listrar speaks it natively

Main obligations

• None in law: adoption is contractual and practical, not statutory
• Structure product URIs as /01/{gtin}, optionally deepened by CPV or serial-level keys
• Serve a resolver that answers those URIs with the right link types
• Keep one identity: the QR on the physical item and the registry record must name the same GTIN

GS1 'Sunrise 2027': retail points of sale worldwide expected to scan QR codes

Products in scope

• Any product that carries a GTIN — which is most products in retail commerce
• Item-level use via serialised keys, where passports demand per-item identity (batteries, for instance)

Obligations by actor

Brand

Encode GTINs as Digital Link URIs on packaging QR codes

Retailer

Scan and resolve the same code at checkout and in-store

Registry

Answer /01/{gtin} with the product's public record — what Listrar does

Agent / crawler

Follow the URI to structured data instead of scraping

Documents and evidence to keep

• Your GS1 licence and GTIN allocations
• The mapping from each GTIN to its resolvable record
• Resolver logs, if you operate your own — they are your proof of availability

Sanctions and risks

• No legal sanction — the risks are commercial
• A QR that resolves nowhere fails retail scanning as Sunrise 2027 arrives
• A DPP whose identifier does not resolve fails the check ESPR builds into customs and surveillance
• Identity drift — one product, several conflicting addresses — is the expensive failure a single canonical record prevents

Key references

• URI syntax — how a GTIN becomes a web address
• GS1 GTIN rules — the allocation rules behind the numbers
