Colorado Address & Name Change

Colorado law requires updates to the address on file with the DMV within 30 days of a move, and updates to a legal name within 30 days of a marriage, divorce, or court-ordered name change. Address updates are free and can be done online; name changes require a counter visit and supporting documents.

When you must report a change

Under § 42-2-119, every Colorado licensed driver must report:

• A change of residential address within 30 days.
• A change of legal name within 30 days.

The same statute requires the address on the vehicle registration to be updated within 30 days. Driver license and registration are tracked separately — updating one does not automatically update the other. Both updates can be initiated through myDMV in the same session, but require two transactions.

Updating your address online

The simplest path is mydmv.colorado.gov. Log in with your driver license number, last four of SSN, and date of birth. The address change is free and takes effect immediately in the DMV database. You can request a printed update sticker for the back of your license for $5, or simply note the change and present any future officer with your old card and the change confirmation.

Online update is unavailable when:

• You have a hold or suspension on your license.
• You're upgrading to a REAL ID at the same time (REAL ID requires two new residency proofs in person).
• Your account has not yet been activated since first issuance of the license.

Updating your address by mail or in person

The paper alternative is DR-2407, the Address Change Notification. Mail it to the Driver Control Section in Lakewood, or drop it off at any driver license office. Counter address changes can be processed during a renewal or duplicate-license visit at no additional charge.

Vehicle registration address

The registration address is updated through your county motor vehicle office, not the state DMV. Most counties accept the change online through their own portal or through myDMV's vehicle services tab. Some counties — particularly the smaller mountain counties — still require the change to be filed in person or by mail with a printed registration card.

If you move between counties, the registration is transferred to your new county at the next renewal. Mid-year moves can be processed by the new county for the standard $7.20 transfer fee — useful when you've moved into an emissions county and need to test the vehicle before the next renewal.

Name change after marriage

To update your driver license and ID after marriage:

• Update your Social Security record first (the DMV verifies the new name through SSA's federal database).
• Visit a driver license office in person.
• Bring a certified copy of your marriage certificate (a photocopy is not accepted).
• Bring your current driver license and any required REAL ID documents.
• Pay the $13.54 duplicate license fee.

The DMV cannot accept the marriage certificate alone — Social Security must show the new name first. Plan on a 2-4 week gap between the SSA update and the DMV visit.

Name change after divorce

For a name change resulting from a divorce, bring a certified divorce decree showing the court order to restore a former name. The same SSA update needs to happen first. The DMV does not accept a divorce decree that simply dissolves the marriage without specifically restoring the former name — that requires either a separate court petition or the marriage-certificate path back to the maiden name.

Court-ordered name change

If your name change is unrelated to marriage or divorce, you'll need a certified copy of the court order from a Colorado district court (or out-of-state equivalent), updated SSA record, and the duplicate license fee. The court order replaces the marriage certificate or divorce decree as the document the DMV verifies.

Updating titles and registration after a name change

Vehicle titles in your old name can be updated at the county motor vehicle office. Bring:

• The current title.
• The certified marriage certificate, divorce decree, or court order.
• Your updated driver license.
• Title fee of $7.20.

The county issues a duplicate title in your new name with the same lien information carried forward. Registration cards are reissued at the same time.

What happens if you don't update

An out-of-date address can cause:

• Missed renewal notices, leading to expired license or registration without warning.
• Missed court-related correspondence — including DMV notices of hearing on suspensions, which run on a strict 20-day response window.
• Failure to receive jury summons or property tax notices, which can trigger separate legal action.
• Citations under § 42-2-119 — a small fine and 1 point on the record if charged.

To verify the address on file at any time, pull a 3-year driving record through myDMV — the record header shows the current registered address. Drivers also reach this page from renewal when they realize the address is wrong before starting a renewal.
