Not sure if you need to move to 2D barcodes? It helps to understand the key differences between traditional 1D barcodes and modern 2D barcodes, and what they mean for your business.
Most food and beverage suppliers are familiar with 1D barcodes, such as the EAN-13, used for scanning products at retail point-of-sale. These barcodes have served us well, but they have limitations, especially when it comes to carrying more data.
2D barcodes, such as the GS1 DataMatrix, are compact and powerful, with the ability to store much more information in a much smaller space. They’re designed for the future of supply chains, traceability, and consumer engagement.
| 1D Barcode (EAN-13) | 2D Barcode (GS1 DataMatrix) | |
|---|---|---|
| Design | A series of vertical black lines with spacing encoding the data. Requires a Quiet Zone. | Square symbol made up of small black and white modules. Also requires a Quiet Zone. |
| Size | Standard size is approx. 38mm wide x 25mm high. | Smaller than 1D. Size depends on the data encoded – can range from 10x10 modules to 144x144. |
| Data capacity | Encodes a 13-digit GTIN (Global Trade Item Number). | Can encode up to 2335 alphanumeric characters or 3116 numeric characters. |
| Type of data | GTIN only. No attributes (e.g. use-by dates, batch numbers). | Supports GTIN plus attributes like batch/lot number, use-by date, serial number, weight, and more. |
| Regulated By | GS1 | GS1 |
| Scanned By | Omnidirectional (laser) scanners. | Optical (camera-based) scanners. |
Not yet. 2D barcodes are not a universal requirement – some products and industries may not need them at all. If you don’t need to encode extra data like expiry dates or batch numbers, you may not need to change your current 1D barcode setup.
Yes, for now. Many retailers still rely on 1D scanners, while others are upgrading to optical scanners that can read 2D codes.
