What Is GS1 Digital Link?
GS1 Digital Link encodes your GTIN inside a regular web URL. One QR code can take a consumer to a product page, send a recall notice, OR scan at retail POS — same code, different reader interprets it differently.
GS1 Digital Link is the GS1 standard for representing GTINs (and other GS1 identifiers) as standard HTTP web URLs. Instead of a 12-digit UPC encoded as a 1D barcode, the product carries a URL like 'https://id.gs1.org/01/00614141123456' encoded as a QR Code or Data Matrix. Scanning that code with a phone camera opens a webpage showing product info, ingredients, recall notices, sustainability data. Scanning it at a retail POS extracts the GTIN '00614141123456' and processes it like a regular barcode.
GS1 is driving toward 'Sunrise 2027' — a coordinated industry transition target for the world's largest brands to add a 2D QR or Data Matrix encoded with GS1 Digital Link to every retail product, alongside (or eventually replacing) the traditional 1D UPC barcode. As of 2026, major brands including PepsiCo, Procter & Gamble, Nestlé, and Walmart are running pilots. Full transition is multi-year and will not happen overnight, but the direction is set.
How GS1 Digital Link encodes data
The standard URL pattern: https://[domain]/[GS1-AI-key]/[value]. Examples: '/01/' = GTIN, '/10/' = batch/lot number, '/17/' = expiry date, '/21/' = serial number. A pharmaceutical product might encode 'https://id.gs1.org/01/00614141123456/10/LOT789/17/281231/21/SN9876' — a single URL containing the GTIN + lot + expiry + serial. The domain can be GS1's official resolver (id.gs1.org), the brand's own domain (https://cocacola.com/01/...), or any registered handler. Brand-owned domains let companies redirect to their own product pages while remaining a valid GS1 Digital Link.
Why brands are moving to GS1 Digital Link
Three drivers. (1) Consumer engagement — scanning a UPC with a phone does nothing useful; scanning a GS1 Digital Link opens a real product webpage with recipes, sustainability data, recall notices, loyalty enrollment. Brands want this engagement surface. (2) Regulatory compliance — EU Digital Product Passport (DPP) regulations starting 2027 require certain product categories (textiles, batteries, electronics) to carry machine-readable URL pointers to compliance data. GS1 Digital Link IS the format. (3) Inventory simplification — instead of a separate UPC, lot code, expiry sticker, and serialization barcode, ONE 2D code carries everything.
Sunrise 2027 — what's actually changing
Sunrise 2027 is a GS1 industry initiative encouraging brands to add a Digital Link 2D code by year-end 2027. NOT a regulation — adoption is voluntary, paced by each brand. Retailers including Walmart, Carrefour, and Tesco have committed to scanning Digital Link at POS by 2027. The 1D UPC barcode is NOT going away — both will coexist on packaging for years. Eventually (2030+), brands will be able to drop the 1D code entirely once retailer POS hardware fully supports 2D-only checkout.
GS1 Digital Link vs regular QR Codes
Regular QR Codes can encode any URL — they're not GS1-aware. A GS1 Digital Link is a SPECIFIC URL PATTERN that any GS1-aware scanner can decode back into structured product data. Both render as the same visual QR/Data Matrix. The difference is the URL inside: a regular product QR might be 'https://cocacola.com/sprite' (just a marketing URL); a GS1 Digital Link would be 'https://cocacola.com/01/00049000028911' (containing the actual GTIN). POS scanners can extract the GTIN from the latter but not the former.
FAQ
What is GS1 Digital Link?
A GS1 standard for encoding GTINs and related identifiers as standard web URLs, rendered as QR Codes or Data Matrix codes on products. Scanning the code with a phone opens a webpage; scanning with a POS scanner extracts the GTIN for checkout. One barcode, two scan contexts.
Will GS1 Digital Link replace UPC barcodes?
Eventually, but not soon. Sunrise 2027 is the industry target for ADDING GS1 Digital Link 2D codes alongside existing 1D UPC barcodes — both coexist on packaging. Full 1D-to-2D transition will take through 2030+ as retailer POS hardware upgrades. The 1D UPC is not dead; it's just gaining a 2D companion.
How do I create a GS1 Digital Link?
URL pattern: https://[your-domain or id.gs1.org]/01/[14-digit GTIN]. Add optional Application Identifiers as path segments: /10/[batch] for lot, /17/[YYMMDD] for expiry, /21/[serial] for serial number. Encode the URL as a QR Code or GS1 DataMatrix using any 2D barcode generator. Validate at the official GS1 Digital Link checker (https://www.gs1.org/services/digital-link).
Does my phone need a special app to scan GS1 Digital Link?
No — any phone camera that scans QR Codes can scan a GS1 Digital Link, because it IS a QR Code (or Data Matrix) containing a URL. The phone treats it like any URL scan: opens a browser. POS scanners need to be GS1-Digital-Link-aware to extract the GTIN at checkout, which is what the 'Sunrise 2027' retailer upgrades are working on.
What is Sunrise 2027?
GS1's industry initiative target: end of 2027 for brands to add a GS1 Digital Link 2D code (QR or Data Matrix) to retail product packaging, and for major retailers to scan both 1D UPC and 2D Digital Link at point-of-sale. Voluntary, not regulatory. Major brand commitments include PepsiCo, P&G, Nestlé, Coca-Cola; major retailer commitments include Walmart, Carrefour, Tesco.
