Decal Number On Car
What is a tag number?
Look at your license plate. On one side is the month sticker and on the other the year. In most states, the label number is on the annual label.
In Oklahoma it will be like numbers, letters and other 6 digits. Your condition may be different. Some states (such as Texas) have bumper stickers on the windshield instead of the license plate.
I think this is the file number or sub-number highlighted on the ticket number.
