Your document number is the eight-digit code printed on the front of your New York driver license, usually below your name or in the upper right corner.
New York calls this the Document Control Number or DCN. It is not the same as your license number (which appears in the center of the card) and not the same as your date of birth or any other identifier on the license. The document number is specific to that physical card and changes if you renew or replace your license.
The number appears in the same location on every New York driver license issued since the state redesigned its license format. If you are looking at your license and cannot find an eight-digit code separate from your main license number, check the upper right area of the front side first — that is where the Department of Motor Vehicles prints it most visibly.

Why New York Uses a Document Number
The document number serves as a unique identifier for that specific card, not for you as a person. This matters because the state needs to track which physical license you hold, especially when you renew, replace a lost or damaged card, or update your information. If you report your license lost and the DMV issues you a replacement, your new card will have a different document number even though your main license number stays the same.
Government agencies and some private organizations ask for the document number when they need to verify that you are presenting a current, valid card rather than an expired or revoked one. The number is also printed on the back of your license in a machine-readable format, which is why some automated systems or law enforcement may reference it.
Where the Document Number Appears on Your Card
On the front of your New York driver license, the document number is printed in the upper right area, usually above or near the expiration date. On some versions of the license, it may appear below your photograph or name instead. The number is always eight digits long and printed in a standard font, not in a barcode or magnetic stripe.
The back of your license also contains the document number in a machine-readable format — a series of lines and numbers that scanners can read. If you cannot locate the number on the front, the back will have it, though you may need a scanner to read it clearly.
When You Need Your Document Number
You will most often need your document number when renewing your license online through the New York DMV website. The online renewal system asks for it to confirm that you are the person requesting the renewal and that your current license is valid. You may also need it when updating your address, name, or other information on your license through the DMV.
Some state agencies, financial institutions, or employers may ask for your document number as part of identity verification, though this is less common than asking for your main license number. If you are unsure whether a request for your document number is legitimate, you can contact the New York DMV directly to confirm.
What Happens When You Renew or Replace Your License
When you renew your New York driver license, the DMV issues you a new card with a new document number. Your main license number — the one in the center of the card — typically stays the same throughout your life, but the document number changes with each renewal or replacement. This is by design: the document number tracks the physical card, not your identity.
If you lose your license and request a replacement before your renewal date, you will receive a new card with a new document number. The old document number becomes inactive, and the DMV's records will show that your current valid license is the one with the new number. Keep your new card in a safe place so you do not have to request another replacement.
How to Read Your License Number Versus Your Document Number
Your license number is the main identifier printed prominently in the center of your card. It is usually 8 or 9 digits and is the number you provide when asked for your "driver license number." This number stays with you for life, even after renewals.
Your document number is the eight-digit code printed separately, usually in the upper right corner. It identifies the specific card you are holding, not you as a driver. If you have ever renewed your license, your document number changed but your license number did not. When filling out forms or providing information over the phone, make sure you are giving the right number — most requests ask for your license number, not your document number.
Frequently Asked Questions
Is my document number the same as my license number?
No. Your license number is the main identifier printed in the center of your card and stays the same for life. Your document number is a separate eight-digit code that changes each time you renew or replace your card. Most forms and requests ask for your license number, not your document number.
What do I do if I cannot find the document number on my license?
Check the upper right corner of the front of your card first. If your license is very old or damaged, the number may be hard to read. You can also contact the New York DMV by phone or visit a local DMV office with your license, and staff can tell you the document number. The back of your card also contains it in machine-readable format.
Do I need my document number to renew my license online?
Yes. The New York DMV online renewal system asks for your document number to verify your identity and confirm that your current license is valid. Have your license in front of you when you start the renewal process so you can enter it correctly.
Will my document number change if I just update my address?
If you update your address without renewing your license, your document number stays the same. The document number only changes when you receive a new physical card — either through renewal or replacement. Address-only changes are handled through the DMV without issuing a new card.
Can I look up my document number online without my license?
The New York DMV does not provide a public tool to look up your document number without your physical license. If you have lost your license and need the document number, contact the DMV directly or visit a local office. They can retrieve it from your record if you provide other identifying information.
