GS1 2D Barcodes and Traceability: What Food Manufacturers Need to Know

Written by Akshita | Oct 26, 2026, 11:41:51 AM

Retailers are moving towards 2D barcodes, and UK supermarkets have already started. This article explains what GS1 Sunrise 2027 means for food manufacturers and how to check your packaging line is ready.

At a glance

    • GS1 Sunrise 2027 is an industry goal for retail checkouts to read GS1 2D barcodes by the end of 2027.
    • It is not a law, and 1D barcodes are not switched off on a set date.
    • Tesco began replacing barcodes with QR codes on own-brand sausage lines in April 2026.
    • Printing a 2D code is not enough. It must print, scan and verify correctly on your line.

 

What is GS1 and why does it matter?

GS1 is a global organisation that develops standards for identifying products, locations and supply chain activity. For food manufacturers, its standards underpin product barcodes, batch identification and traceability.

Standardised identification helps businesses record and share product data from manufacturing and packing through to distribution and retail. It supports more than checkout scanning, including inventory management, quality control and product recalls. [1]

 

From 1D barcodes to 2D codes

GS1 has standards for five 2D barcodes. The two most widely recognised are:

    • QR Code with GS1 Digital Link: encodes a web-style link that can also lead shoppers to ingredients, allergens, nutrition, recycling or usage information.
    • GS1 DataMatrix: widely used in healthcare, and carries data in GS1's element-string format. [2]

 

What is GS1 Sunrise 2027?

GS1 Sunrise 2027 is a global industry goal. By the end of 2027, retail point-of-sale (POS) systems should be able to read and process a defined set of GS1 2D barcodes, in addition to existing linear barcodes. [3]

Three points are easy to get wrong:

    • It is not a regulation. It is a coordinated industry target.
    • 1D barcodes won't vanish overnight. The shift is progressive and varies by market and retailer. [3]
    • It is about retail readiness. What your customers require, and when, is the real deadline for your business.

 

What's happening in the UK now

In April 2026, Tesco began replacing traditional barcodes with QR codes on its own-label sausage range, describing it as a UK first. The codes give shoppers product information and let the retailer identify specific batches in a recall, rather than pulling whole product categories from sale. GS1 UK's chief executive, Anne Godfrey, called it a "significant step forward for UK retail". [4]

This follows an earlier Tesco pilot with GS1 UK and ten supplier partners. It covered 12 own-brand meat and produce lines and focused on capturing use-by dates and batch numbers. [5]

For food manufacturers, the message is clear: 2D codes are already appearing on UK shelves.

 

What this means for packaging and inspection

Moving to 2D codes involves more than choosing a new format. You need to consider how codes are generated, printed, positioned, captured and verified.

 

What can affect readability:

    • print quality and code size
    • packaging material and surface
    • product orientation
    • line speed

 

Why verification matters: a QR code can look perfect and still be wrong. The data may be structured incorrectly, or the print quality may fall below what a retailer requires. For example, one supplier guide reports that Tesco's guidance for fresh products sets a minimum print grade of B. [6] Confirm the exact requirement with each retail customer.

 

A practical check: during the transition, packs will often carry both a 1D and a 2D code. Inspection should confirm that both codes read and that the product number in each match. [7]

Automated vision and inspection systems can check these things in-line, at production speed. The right setup depends on your code type, packaging format, environment and verification criteria.

 

How can SPUK and Antares Vision help?

SPUK supplies Antares Vision Group's label inspection solution, which checks codes and labels on every pack as it moves down the line. It reads and now also grades printed codes, so poor print quality can be caught on the line rather than at the retailer-level.

Why code grading matters now

GS1 UK says that an unverified QR code on pack is a liability, and that a code scanning on a phone does not guarantee it will scan at the till. They also say the industry needs inline verification that matches the accuracy of ISO-graded offline checks, because current inline solutions are not ISO-graded. [8]

Antares Vision Group's label inspection solution grades the print quality of every code inline, against the standards that GS1's verification templates are based on. [9] If a code falls short, the rejection system automatically removes the pack.

 

Reads and grades GS1 codes

The system inspects all GS1 barcodes and has always been able to read them. Barcode grading is the latest addition, so it can now assess print quality as well as readability.

It supports all the code types covered in this article:

    • QR Code with GS1 Digital Link
    • GS1 DataMatrix
    • 1D barcodes

 

Suits a range of packaging and line speeds

    • Horizontal machines inspect flat-lying packs such as trays, bags, thermoformed packs and flow wraps. Speeds reach up to 130 packs per minute on the standard machine, and 130+ is achievable if required.
    • Vertical machines inspect wet food packaging such as bottles, jars, tins and cans. They use 360-degree cameras and can run at full bottling line speeds.

 

More than code checking

The same machine also carries out the standard inspections:

    • OCR
    • date code reading and checking
    • date and weight checks
    • label alignment
    • presence
    • rotation
    • compliance and quality checks

 

Why a complete machine rather than bolt-on cameras

Compared with bolt-on cameras, this is a complete machine with its own rejection system, which is fully retail compliant. It is also compact, taking roughly 1.22 m of line length.

It can also be added that Antares Vision Group's All In One Solution, combines it with other technologies such as lead detection, X-ray, and more in an even smaller footprint.

 

Is your line ready? A quick checklist

    • Ask your retail customers what 2D requirements they have and when.
    • Review your coding equipment. Can it print the codes you will need, at the quality required?
    • Plan your data. Decide what each code will carry and where the link will point.
    • Test and verify. Check codes are readable and meet the print grade on the live line.
    • Plan the transition. Many products will carry 1D and 2D codes side by side for a while.

 

Preparing for the next generation of barcodes

2D codes are moving from pilot to practice, and the manufacturers supplying retailers will feel the change first. Two questions are worth asking now:

    • Do you know what your retail customers will expect from the codes on your packaging, and by when?
    • If they asked tomorrow, could you show that every code leaving your line prints, reads and grades correctly?

If you're not sure of either answer yet, now is the time to check your packaging line, so you can supply your retailers with confidence.

 

Conclusion

2D codes are moving from pilot to practice, and for food manufacturers supplying retailers, print quality now matters as much as the data in the code. With Antares Vision Group's label inspection solution, Sealpac UK helps manufacturers read and grade every code on the line, so they can supply their retailers with confidence as GS1 Sunrise 2027 approaches.
