It Is Critical To Use Your Check Digit Calculations When Assigning Your UPC-A To Your Products.

Here Is An Example You Can Use On Any Product That Carries A GTIN-12 (UPC-A)

NOTE: You Can Use Anything In Your Home With A 12Digit GTIN (UPC-A) (NUMBERS BELOW BARCODE)

I Just Assigned A GTIN-12 To A Product I'm About To Release

My 12Digit GTIN AKA U.P.C Needs To Be Checked For Errors.
****PLEASE REMEMBER TO EXCLUDE THE 12TH DIGIT. IF DONE CORRECTLY YOUR RESULT WILL EQUAL THIS LAST DIGIT. IF NOT YOU MUST FIND THE ROOT CAUSE OF THE ERROR.***

1.Add the odd number digits: 0+6+0+2+1+5 = 14
*Multiply the result by 3 (14 × 3 = 42.)
2.Add the even number digits: 3+0+0+4+4 = 11
*Add the two results together: (42 + 11 = 53)
*To calculate the check digit, take the remainder of (53 / 10), which is also known as (Modulo 10), and if not 0, subtract from 10. Therefore, the check digit value is 7.
(53 / 10) = 5 remainder 3; 10 - 3 = 7.
