Treat 2D migration as a data-and-line project, not only a printer change. Define the carrier, encoded identifiers, artwork, print method, verification grade, scanner capability, data ownership and coexistence with linear barcodes.
Why this matters
GS1’s 2027 ambition is for retail point-of-sale systems to be capable of reading and processing defined 2D barcodes alongside current barcodes. Early production tests are important because speed, substrate, curvature and data systems all affect readiness.
Decision table
| Workstream | Question | Evidence |
|---|---|---|
| Data | Which identifiers and attributes are required? | Controlled data model |
| Carrier | GS1 QR Code or GS1 DataMatrix? | Approved symbol specification |
| Printing | Preprinted, inline variable or label? | Trials at normal speed |
| Verification | What grade and quiet zone? | Verification reports |
| Scanning | Can line and downstream systems process it? | End-to-end scan test |
| Governance | Who approves and changes data? | Change-control process |
Information to collect first
- Identify every pack level and current barcode.
- Define the 2D use case and encoded data.
- Confirm printer resolution and print window.
- Test normal speed and worst-case contrast.
- Verify with appropriate equipment, not only a phone.
- Run end-to-end scanner and data tests.
Recommended method
- 1
Start with one product and line.
- 2
Create controlled test data and artwork.
- 3
Prove print and verification.
- 4
Check warehouse and customer interfaces.
- 5
Plan linear and 2D coexistence.
Common mistakes to avoid
- Adding a symbol without data ownership.
- Using a phone scan as the only quality test.
- Ignoring curved, reflective or wet surfaces.
- Reducing symbol size without verification.
- Assuming every retailer changes at the same time.
Questions people also ask
What is Sunrise 2027?
The common name for the GS1 ambition that retail POS systems should be capable of processing defined 2D barcodes by the end of 2027.
Will linear barcodes disappear immediately?
No. Coexistence is expected; confirm customer and market requirements.
Which 2D barcode should be used?
The choice depends on the use case and trading-partner requirements.
Can existing coders print 2D?
Some can, depending on resolution, distance, speed, substrate and code size; prove the result.
