Where to Find the Longmont DMV Office

Longmont does not have its own dedicated Department of Motor Vehicles office. Instead, residents handle driver's license renewals, vehicle registration, and title work through the Boulder County Clerk and Recorder's office, which operates the motor vehicle services for the area. The main office is located at 1750 33rd Street in Boulder, about 20 miles south of Longmont.

If traveling to Boulder is not practical, you can also visit the Longmont City and County Building at 350 Kimbark Street in Longmont, which offers limited motor vehicle services. This location handles some transactions but does not process all services — you will want to call ahead to confirm whether your specific need can be handled there.

Colorado also allows many transactions online through the state DMV website or by mail, which can save you a trip entirely. The state's online system handles renewals for many drivers, vehicle registration renewals, and address changes without visiting an office.

Key Takeaways

  • Longmont residents use Boulder County Clerk and Recorder services in Boulder or the limited services at Longmont City and County Building for motor vehicle transactions.
  • Many driver's license renewals and vehicle registration renewals can be completed online through Colorado's DMV website without visiting an office.
  • The Boulder County office is the full-service location and handles all motor vehicle transactions, including title work and commercial licenses.
  • Calling ahead to the Longmont location is necessary to confirm whether your specific transaction can be processed there.
  • Colorado accepts mail-in renewals for many transactions, which is another option if you cannot visit an office in person.

What You Can Do Online or by Mail

Colorado's online DMV system lets you renew your driver's license if you meet certain conditions: your license must not be expired by more than one year, you must have a valid Social Security number on file, and you cannot have any medical restrictions or violations that require an in-person review. Most standard renewals fit these requirements.

Vehicle registration renewals also happen online in most cases. You will need your vehicle identification number (VIN), current registration, and a payment method. The state sends your new registration documents by mail after processing.

If you prefer not to use the online system, you can mail renewal forms to the Boulder County Clerk and Recorder office. Request the forms by phone or read them from the Colorado DMV website. Processing by mail takes longer than online — typically two to three weeks — so plan ahead if your registration or license is expiring soon.

Services at the Boulder County Office

The Boulder County Clerk and Recorder at 1750 33rd Street in Boulder handles the full range of motor vehicle services. This includes driver's license applications and renewals, vehicle registration and title transfers, commercial driver's license (CDL) services, and duplicate license or registration documents.

The office also processes address changes on your driver's license and registration, handles vehicle ownership transfers when you buy or sell a car, and issues duplicate titles if yours is lost or damaged. If your transaction is complex — such as registering a vehicle from out of state or dealing with a lien holder — this is the location that can walk you through the process.

Hours and wait times vary by day and season. The office is typically busier on Fridays and at the beginning of the month. Calling ahead at the Boulder County Clerk and Recorder office can give you a sense of current wait times and confirm that you have all required documents before you make the drive.

Documents You Will Need

For a driver's license renewal, bring your current license, proof of Colorado residency (such as a utility bill or lease dated within 60 days), and your Social Security number. If your address has changed, bring a document showing your new address.

For vehicle registration renewal, you will need your current registration, proof of insurance, and payment. If you are registering a vehicle for the first time in Colorado, you will also need the title, a bill of sale, and proof of ownership.

For a title transfer when buying a vehicle, bring the signed title from the seller, a bill of sale, proof of insurance, and identification. If the vehicle has a lien (the bank or lender still owns it), bring documentation from the lender as well.

Bring original documents or certified copies — photocopies are not accepted for most transactions. If you are unsure whether a document counts as proof of residency or ownership, call the Boulder County office before your visit.

Handling an Address Change

You can change your address on your driver's license and vehicle registration online through Colorado's DMV system if you are only updating your mailing address. The change takes effect when ready for your registration and within a few days for your license.

If you need a new physical license card with your updated address printed on it, you must visit an office in person. The Boulder County office or the Longmont City and County Building can issue a replacement card with your new address. Bring your current license, proof of your new address, and identification.

Changing your address is important for vehicle registration because Colorado uses your registration address to send renewal notices and any traffic citations. If you move and do not update your address, you may miss renewal important date or not receive important notices from the state.

When You Need to Visit in Person

Some transactions require an in-person visit to an office. These include your first driver's license process in Colorado, a CDL process or renewal, a license renewal when you have medical restrictions or violations, and obtaining a duplicate title when the original is lost.

If your driver's license has been suspended or revoked, you must visit an office to understand the requirements for reinstatement. The same applies if you are renewing your license after it has been expired for more than one year.

Vehicle title transfers when you buy a car also require an in-person visit or a notarized signature from the seller if you are handling it by mail. The Boulder County office can notarize documents if needed, though you may also use a bank or notary service in Longmont.

Frequently Asked Questions

Can I renew my driver's license at the Longmont location instead of driving to Boulder?

The Longmont City and County Building offers limited services, so you need to call ahead to confirm whether license renewal is available that day. If your renewal is straightforward, they may be able to help. For complex transactions or if they cannot process your renewal, you will need to visit the Boulder County office.

How long does a vehicle registration renewal take if I do it online?

Online registration renewals are processed within a few business days, and your new registration documents arrive by mail within one to two weeks. If you need your registration when ready, visit an office in person and they can issue a temporary registration on the spot.

What if I moved to Longmont from another state and need to register my vehicle in Colorado?

You will need to visit the Boulder County office in person with your out-of-state title, a bill of sale, proof of insurance, and identification. The office will issue a Colorado title and registration. This cannot be done online or by mail for first-time Colorado registrations.

Do I need an appointment to visit the DMV office in Boulder?

The Boulder County Clerk and Recorder office operates on a first-come, first-served basis and does not require appointments. However, you can call ahead to ask about current wait times and confirm your documents are complete before you visit.

Can I handle my vehicle title transfer by mail if I am buying a car from someone in Longmont?

Yes, if the seller signs the title and has it notarized, you can mail the completed documents to the Boulder County Clerk and Recorder office along with your bill of sale and proof of insurance. Processing takes two to three weeks by mail, so plan accordingly if you need your registration quickly.
