GS1 is the only provider of authentic, globally recognised barcodes, meaning that if you apply GS1 barcodes to your product, your product can be identified and scanned all over the world.

In order to put barcodes on your products, you need to first sign up as a member. Then you will be able to upload your products, generate barcodes and barcode graphics and then you can start selling to your trading partners!

We helped Sachie's Kitchen get started, watch their story below

Barcodes are symbols that can be scanned electronically using laser or camera-based systems to read numbers or other data. They are used to encode information such as product numbers, serial numbers and batch numbers. Barcodes play a key role in supply chains, enabling parties like retailers, manufacturers, transport providers and hospitals to automatically identify and track products as they move through the supply chain. There are also several types of barcodes to view all the different types see our standards section. For more technical information about GS1 barcodes visit the Help Centre.


What is a Global Trade Item Number (GTIN)?

A GTIN is a globally unique GS1 identification number allocated to any product or service that may be priced, or ordered, or invoiced at any point in any supply chain.The GTIN is the ‘number’ part of the barcode, encoded in one of several types of barcode depending on the nature of the product and the environment in which it will be scanned (retail, distribution or both). It is made up of:

  • Your global company prefix (allocated to you by GS1)
  • An item number (allocated by you to each product variant)
  • A check digit

Please note that the GTIN exists independently of barcodes. While it can be encoded in various types of barcodes it is also usable in Radio Frequency Identification (RFID) tags as well as in electronic communications in lieu of text descriptions of the product or service. 

Barcode Verification

Once you have a barcoded product, you need to ensure the GTIN is correctly formatted and allocated and that the barcode scans first time, every time. Many retailers will ask you to get your barcode verified before you submit your product into to their stores. Barcode verification service tests number correctness and barcode quality and it is required before you can start supplying your trading partners.

There are two things you can do to calculate the Check Digit:

  1. Go to the GS1 global website's Check Digit Calculator, where you can use the calculator or follow the instructions to manually calculate the Check Digit.
  2. Login to MyGS1 and use ProductVault - an online service from GS1 New Zealand that guides you through the allocation of product identifiers (Global Trade Item Numbers, GTINs) to your products and product hierarchies (inners, cases, pallets). ProductVault will automatically calculate the Check Digit for you. Watch our video tutorial.
