Standards

GS1 Standards Hub: Digital Link, GTIN, EU ESPR & Sunrise 2027

Every brand putting a 2D barcode on its next packaging refresh touches the same handful of standards. Here is a plain-English map of what each one means, what it asks of you, and how the platform maps to its data fields.

The four you'll meet

Click any one for the long form. Each page explains what the standard says, who is enforcing it, and which platform fields and modules you use to satisfy it.

Web URI syntax

GS1 Digital Link

The format that turns a GTIN into a real, resolvable URL on your domain. The thing your QR encodes. The thing the consumer's phone opens. The thing a 2D-capable retail scanner reads at the till.

  • URI pattern /01/{gtin}/10/{batch}/21/{serial}
  • Backwards compatible with old EAN-13
  • Human readable and machine readable

Global Trade Item Number

GTIN

The universal product identity number GS1 allocates and retailers recognise at point-of-sale. Already on your existing barcode artwork. We validate the mod-10 check digit and carry it into the Digital Link URL.

  • GTIN-8, GTIN-12, GTIN-13, GTIN-14
  • Mod-10 check digit validation
  • Allocated by GS1 in your country, not by us

Retail point-of-sale milestone

Sunrise 2027

The global industry goal that retail point-of-sale scanners should be able to read 2D barcodes carrying GS1 Digital Link URLs by the end of 2027. This is the deadline that drives most packaging migrations happening now.

  • Not an outright ban on 1D barcodes
  • Most retailers planning dual-marking transition
  • Drives your next packaging refresh window

Digital Product Passport framework

EU ESPR

The Ecodesign for Sustainable Products Regulation. Sets the data fields a Digital Product Passport must carry, by category, through delegated acts. The platform's passport sections map directly to ESPR's data attributes.

  • Identity, materials, durability, repair, recycling
  • Supply-chain provenance and certifications
  • Per-category delegated acts roll out 2025–2030

How the platform maps to each standard

These four standards are not abstract. Each one corresponds to specific fields, modules and exports inside the dashboard.

Digital Link → URL builder

Workspace-level resolver hostname, GTIN qualifier validation, AI 10/21 batch and serial qualifiers in the URL.

Identity module

GTIN → mod-10 validation

Inline validation on every product create or edit. Locked once published so the public URL stays stable.

Validate the GTIN

Sunrise 2027 → 2D readiness

Self-assessment checklist for DPP, FSMA, EUDR and GS1 Verified. PNG, SVG and PDF QR exports your printer accepts.

Migration plan

ESPR → passport sections

Identity, story, ingredients, materials, recycling, certifications, attributes and supply chain. ESPR-aligned out of the box.

Quick answers

Do I have to follow all four standards?
No, but most brands touch all of them eventually. GTIN and GS1 Digital Link are the universal layer that everything else sits on. Sunrise 2027 is a retail readiness goal. EU ESPR applies once you sell in the EU and your category is in scope.
Are these standards compatible with each other?
Yes. They are designed to compose. A GS1 Digital Link URL carrying a valid GTIN is simultaneously the retail identity, the consumer scan target, and the data-bearer for an EU Digital Product Passport. One code, four standards.
Where does GS1 fit in?
GS1 is the standards body that maintains GTIN, the Application Identifier framework, and the GS1 Digital Link specification. They allocate GTINs through national member organizations and publish the format documentation. We follow their rules and validate against them.
Does ESPR apply to my product category?
ESPR is the EU framework, but enforcement and data fields come per-category through delegated acts. Iron and steel, batteries, textiles, electronics, ICT, chemicals and several other priority categories are first. Food and pharma have their own parallel regimes (FSMA 204 in the US, EUDR in the EU for deforestation-linked commodities).
