Import your GS1 prefix and generate unlimited UPCs
Manage your own GS1 company prefix from Barbar. Auto-generate UPCs, track usage, and never miss a renewal.
What Is a GS1 Prefix?
A GS1 company prefix is a unique number assigned to your business by GS1, the global standards organization behind UPC barcodes. It forms the first digits of every UPC you create, identifying your company as the product owner.
The length of your prefix determines how many UPCs you can generate. For example, a 7-digit prefix gives you capacity for up to 100,000 UPCs, while a 10-digit prefix gives you 100 UPCs.
If you already have a GS1 prefix, Barbar lets you import it and manage everything from one dashboard. If you don't need your own prefix, you can buy individual UPCs instead.
