  5. Most product UPC codes have twelve digits. The first six numbers define the manufacturer or vendor of the product. Every product that the vendor sells will have the same first six numbers last number is a special digit called the "check digit"

  6. Check Digit This "check digit" has a mathematical formula It confirms that the product is accurately checked.

  7. The code is 013000001243 Step One: Add the digits in the odd positions together: • 0+ 3+ 0+ 0+ 1+ 4= 8 Step Two: Multiply the answer in step one by 3

  8. Step Three: Step Three: Add the digits in the even positions (except for the 12th digit) • 1+ 0+ 0+ 0+ 2+ = 8 Step Two: Add the answer from Step Three to the answer in Step Two 3 + 24 = 27

  9. Step Five: Add the check digit (in this case 3) to the answer from Step Four (27) • 3 + 27 = 30 Step Six: This check digit must be a multiple of ten to be accurate, and the first digit of the answer (a multiple of ten) is used as the check digit. 3 + 24 = 27

  10. Each time that a UPC is read by a barcode scanner, this calculation is automatically performed. If the check digit is different than the one that is calculated, then the computer knows that there is something wrong with the UPC.
