This is most often needed for twins. I have no idea what they do after that. Once you have figured out the rest of the license number you can alternate adding and subtracting the numeric value of each character.
The checksum is the single digit remaining, ignoring negative signs or the fact it might be more than 9. In other words, answers of 6, 16 and -6 will all have a checksum digit of 6.
The mathematical way to write this is:. Use to convert the letters in the license number into numbers, before calculating the checksum the 8th character in the license number. There you go. I have not found the answer for what happens when the triplet, Justin Wilkins Smith, comes in for his license. Otherwise they are almost identical, including the number.

The Checksum did not work however, it added up to be a 9, but was issued as a 7 but I was able to get close enough to guess and verify DL status to see that it was right.

About the little numbers. When they take your picture, it is given a distinct number. Also, if you look at line 5, after the number is a DD then your DL number and then the same number that is on your picture added to it for a very long number.
Again, linking the photo with the DL number. What does 5DD on the bottom a washington state drivers license mean, it seams to change with every address?

What is the code for date 31? Thank you! You sir, are epic. Could you decipher mine please? I cant figure how to get the last digit after my birthyear!
I have always thought the answer would be 1 but it appears it is 9. When I plug in -1 mod 10 into Google it shows the answer is 9.
