Start creating barcodes

Now you’re one step closer to getting your products on the market – both locally and globally. Follow these steps to create numbers and barcodes with your GS1 Company Prefix.

Before you can create a barcode, you need a number that identifies your product. This is the same number you see under a barcode and is called GTIN (Global Trade Item Number). A GTIN-13 is a 13-digit number consisting of: GS1 Company Prefix + Serial Number + Check digit

GS1 Company Prefix is the number you got when you joined GS1. It identifies your company and is always a part of all other GS1 numbers you create.

Serial Number is controlled by you. It can be from 000 to 999 if you ordered 1,000 numbers. The length of the serial number depends on the length of the company prefix.

Check digit is the last digit of a barcode number: It is a computer check digit and you need to use our check digit calculator to generate it for every barcode you create.

Recommendation

  • We recommend numbering your serial numbers in order of sequence.
  • Make sure to have a system to keep track of which numbers you created and what the number identifies.


When you have a GTIN, you can produce a barcode for the product. The most common barcode type for marking packaging that will pass through a check-out point, both in Sweden and in the rest of the world, is EAN-13. EAN-13 is also used to label cases.

GS1 Company prefix can be used for much more than creating barcodes. Watch the video to see all areas of use of the company prefix.
