To verify if your UPC barcode is valid, first, count the digits to ensure it's 12. Then, add together the digits in odd positions (excluding the last digit), and separately sum the digits in even positions, multiply the even sum by 3, add both results together, and subtract from the next higher multiple of 10. If the result matches the last digit of the UPC, it’s valid.
