  1. UPC (Universal Product Code)[Also known as the GTIN-12] How to format a UPC

  2. Format of GS1 standards • All GS1 numbers (UPC, GTIN, SSCC, GLN) essentially have 3 parts: • Company Prefix = a number assigned and managed by GS1 that uniquely identifies a company from any other company across the globe. • Reference Number = assigned by the owner of the Company Prefix to identify what is being numbered (e.g. a pallet, a case, an item, a location, etc.) • Check Digit = an algorithm that serves as a “checks and balances” to ensure preceding digits were entered correctly. NOTE: All three parts must not be separated in order to maintain uniqueness

  3. GS1 Data Structures GTIN 14 digits SSCC 18 digits GLN 13 digits UPC 12 digits X X X X X X X X X X X X X X Item Item/Case Pallet Location NOTE: The Company Prefix can vary from 6 digits to 9 digits. As such, the reference # will also vary depending on the size of the Company Prefix.

  6. Example of a U.P.C. (item level) Company Prefix Reference Number (i.e. Item Number) Check Digit NOTE: The Company Prefix can vary from 6 digits to 9 digits. As such, the reference # will also vary depending on the size of the Company Prefix.
