How do I create a 2D barcode?

Before you dive into creating 2D barcodes, take a moment to assess your product, packaging, and production setup. Planning ahead will save time, money and rework and help you get it right the first time.

Start with the basics

 
  • Is your product fixed or variable weight?
    This will influence the timing and type of barcode transition. Variable weight products (like fresh meat) may have different requirements from fixed weight items.
  • Which 2D barcode format do you need?
    Not all 2D barcode types are suitable for use at point-of-sale. GS1 DataMatrix is the most widely used in retail applications.
  • Will your packaging need to change?
    2D barcodes are square, not rectangular like linear barcodes. That may mean adjusting your packaging layout.
  • Do you have the right equipment to apply 2D barcodes?
    In-line printing and scanning technology may need to be upgraded to ensure the codes are applied, printed and validated correctly.

Pro Tip: Engage your trusted coding and labelling partners like Reynolds as early as possible to avoid costly surprises. They’ll help ensure your 2D barcodes scan first time, every time.

Become a member of GS1 NZ

GS1 is the global standards organisation responsible for barcodes, including 2D DataMatrix. To create GS1-compliant 2D barcodes, you’ll need to use Application Identifiers (AIs) – these are 2, 3 or 4-digit numbers that tell systems what kind of data is being read (e.g., batch number, expiry date, etc.).

If you already have GTINs for your products, you’re likely a member of GS1. If not, contact GS1 New Zealand to get started.

Work with your coding & labelling partners

Talk to your solution partners, like Reynolds, as early in the process as possible. They can guide you through equipment upgrades, printing capabilities, and testing, so you can transition smoothly to 2D barcodes without disruption.

 

A few key points:

  • You’ll need in-line printing or labelling systems for 2D codes. Pre-printed codes or labels won’t meet all use cases.
  • Print quality and barcode placement are critical. Poor-quality codes may not scan, costing you time and trust.
  • A good partner will help you test and trial your solution before rollout, to ensure it works consistently on your production line.
