LEARN
Everything we know about 2D codes, written down.
GS1 explainers, product documentation, and what actually changed in the specifications — one library, because a founder asking what a link type is and an engineer reading the reference are usually the same person on different days.
FILTER THE LIBRARY
Sunrise 2027, explained for people who make things
What GS1's 2027 goal for 2D barcodes at checkout actually says, what it does not say, and why the deadline that matters to a brand is its next print run rather than a date.
Read the explainer →GS1 CHANGELOG
The specifications move. We track them so your artwork does not go to a printer against a version that changed last month.

Show everything (8) →Our GS1 resolver conformance run
A dated run of GS1's public resolver conformance test suite against a live packagepage resolver — the result, the raw output, the one warning it returned, and the thing the suite does not test.
Why we will not let you write custom CSS on your product page
Consumer product pages are themed with typed tokens rather than a stylesheet. The reason is the allergen block, and it is the one product decision we are not willing to negotiate.
Publishing a recall notice
What happens when you publish a recall notice, exactly who it reaches, why it writes two links to every affected grain rather than one, and why it is free and ungated on every plan.
The regulatory deadlines, and which of them are actually law
Sunrise 2027 is an industry goal with nobody to enforce it. These are the rules that can be enforced — what each one requires, when it applies, and how sure we are of each date.
Sunrise 2027, explained for people who make things
What GS1's 2027 goal for 2D barcodes at checkout actually says, what it does not say, and why the deadline that matters to a brand is its next print run rather than a date.
GS1 General Specifications 26.0
The General Specifications release packagepage generates and checks artwork against, ratified 26 January 2026 — what it governs, and what it means for labels already at a printer.
GS1-Conformant Resolver Standard 1.2.0
The resolver standard release packagepage is built and tested against, ratified in January 2026 — what it governs, and why it changes nothing about artwork already at a printer.
2D Barcodes at Retail POS Implementation Guideline 1.1.0
The guideline that defines which 2D carriers are usable at a checkout lane and states the 2027 goal, ratified December 2025 — and what it means for artwork already at a printer.
