What is a GS1 Company Prefix?

A GS1 Company Prefix:

  • Used within the GS1 identification system to identify trade items and logistics units.
  • 7-10 digits in length
  • SHC Vendors are required to be GS1 members, unless they are the sole distributor for an item belonging to a GS1 member.
  • Assigned by a GS1 organization (www.gs1.org) to a GS1 member.
  • Companies which have a GS1 Company Prefix assigned by the GS1 US (www.gs1us.org) ALWAYS begin with the number "0".

For companies who registered with the United States GS1 Organization, their UPC prefix is their GS1 Company Prefix with the first leading zero removed.
