What the numbers and letters on your Missouri license tell you

Your Missouri driver's license number is a unique identifier printed on the front of your card. It is not a Social Security number, a random string, or something you choose yourself — Missouri assigns it to you based on your name and date of birth using a specific formula. Understanding what your number represents and where to locate it can help you when you need to provide it to insurance companies, law enforcement, or the state.

The number appears in the upper right corner of your physical license card and is also listed on your digital license if you use the Missouri Digital License app. You will need this number whenever you renew your license, update your address, or provide proof of licensure to an employer or insurance company.

How Missouri generates your license number

Missouri uses an algorithmic system to create driver's license numbers rather than assigning them sequentially. The formula takes your last name, first name, middle name (if you have one), and date of birth and converts them into a nine-digit number. This means that if you were born on the same day as someone else with the same name, you would receive the same license number — though this is extremely rare.

Because the number is generated from your personal information, it will remain the same throughout your life unless you legally change your name. If you change your name through marriage, divorce, or court order, you will receive a new license number when you update your license with the Missouri Department of Revenue.

The formula is not random, so you cannot predict or calculate your own number in advance. Only the Missouri Department of Revenue can generate it when you first explore for a license.
