If you plan to sell your products on Amazon, you will need a barcode with a GTIN number (also known as UPC or EAN number). This number can be found under the barcode on each product. Amazon uses the number to easily identify products in their product catalog and as a seller you get several unique benefits such as;
Higher purchase rate
Higher rates of conversions/purchases when using Global Trade Item Numbers (GTIN).
Product feeds with GTINs are eligible for Google shopping ads and organic search.
Data source linking
GTINs enable the connection of all product information, videos, consumer reviews, pictures, prices, etc.
If you already use GTIN, you don’t need to create new numbers to sell on Amazon. This will improve efficiencies and visibility, as you can add your products more quickly and with less friction.
Follow our step by step guide on how to get a GTIN to make your products ready to be sold on Amazon.
1. Become a GS1 customer
You need a unique number to identify each product. For one item, a single number is sufficient, but to identify several you need a GS1 Company prefix. You get this by becoming a customer of GS1. If you are already a GS1 customer, go directly to step 3.
2. Use your company prefix
GS1 Company Prefix is your company’s unique number that unlocks the ability to use all GS1 standards and services. The prefix is licensed to your company and with it you create series with unique numbers and barcodes.
How it works
Your company prefix
When you join GS1, you get a unique company prefix which is the basis for creating GTIN for identification of your products. This image illustrates a barcode and a GTIN with the company prefix is marked in red.
When the company prefix is enabled, no other organization can use it to create numbers. The company prefix belongs to your organization and you use it to uniquely identify your products so that they are ready for trade.
The length of your prefix depends on the size of the number sequence you have ordered. You can use your prefix to create different types of numbers depending on whether you identify products, packaging, pallets, inventory, locations etc.
Unique identification of books, sheet music and magazines
Books, notes and magazines can be numbered with GTIN-13 in the same way as other goods. It is also possible to turn the industry codes ISBN (for books), ISMN (for music sheets and notes) and ISSN (for periodicals) into a GTIN-13. It is the Royal Library that hand out ISBN, ISMN and ISSN. If you have questions about numbering books, sheet music and journals, please contact the Royal Library.
Tidsam will answer questions regarding identifying magazines distributed by them.
Labelling of products
The barcode type for encoding GTIN is usually EAN-13. If your product is too small to be labeled with the standard 13-digit barcode, you need to use a special 8-digit GTIN that generates a shorter barcode. These numbers are used only in exceptional cases.
Create barcode labels
You can either make barcode originals yourself or hire someone to do it for you, for example a packaging designer, advertising agency or commercial printer.
We have listed some suggestions for barcode vendors that we know follow our barcode size guide. You can of course use a printing service or similar, but please refer them to our size guide. See barcode suppliers ›
Once you have your barcode label ready, you can use our BarcodeCheck. BarcodeCheck is our service to check the readability, content and quality of barcodes. We also ensure that your barcodes comply with GS1 standards.
Understand the GTIN rules
A new GTIN is always required for a new product. If you’ve made changes to a current product, you may also need a new GTIN. For example, there may be a major change in ingredients or if the size or color has changed.
GS1’s global website lists GTIN rules that require a new GTIN listed.
