How to format a Generic 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

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.

IMPORTANT NOTE: The use of the Generic Company Prefix
does not allow a buyer to distinguish one company from another. As
such, this number is NOT recommended for companies looking to
distinguish the product between companies who use this same prefix.
