Build a Sample U.P.C. Barcode

Use your U.P.C. Company Prefix to create and view practice barcodes

The number in a U.P.C. barcode (called a GTIN®) is typically 12 digits long. This tool helps illustrate how you create a GTIN-12

  • It starts with your U.P.C. Company Prefix that was assigned to your company when it became a member of GS1 US. Your U.P.C. Company Prefix could be between six and ten digits long
  • The next one to five digits are for the item reference numbers that you will assign to your unique product variations
  • The 12th digit is called the check digit, which is calculated based on the other numbers in the GTIN-12 and ensures accuracy
