Boulder County government offices closed Thursday, Nov. 28, and Friday, Nov. 29, for the Thanksgiving holiday.

Appointments now required for in-person visits. Additionally, registration renewals need to be completed out of office. Options include online, by mail or drop box, or at a self-service kiosk. Read about these changes (including benefits, and FAQs). Información en español.

October Vehicle Registration Renewals Alert: If your vehicle registration is up for Oct renewal, the postcard will say proof of insurance required. For 99% of residents, it is not. We have it in our records. Try to renew online or other method first as you should be fine if nothing has changed with your car insurance. See the Colorado Dept of Motor Vehicle statement for more information.

Drop Boxes for Boulder County Motor Vehicle Division

Drop Box Locations

For your convenience, we have three drop boxes available for MV paperwork:

Completing Vehicle Registration Renewals via Drop Box

Drop boxes can be used for submitting a variety of Motor Vehicle paperwork (see below), but they are most commonly used for completing vehicle registration renewals. Please follow these registration renewal instructions carefully to prevent any undue delays in processing your renewal.

  • Note about the new Keep Colorado Wild Pass – Starting January 2023, you will see an option on your renewal card to pay $29 for a Keep Colorado Wild (State Parks) Pass. This fee will be automatically included in the price of your renewal unless you opt out. (If you would like to opt out, follow the instructions on your renewal card.)

Renewals must be received by the last day of the grace period (one month after the expiration month).

If using the drop box, please allow up to two business days for us to process your renewal. Additionally, please return your renewal before the end of your grace month (one month after expiration) to avoid late fees.

Registration renewal with new stickers will then be mailed to your registration address. Please allow up to a week for mail. Thus, if using the drop box, expect the total turnaround time to be between 7-10 days to receive your renewal.

The following services may also be completed via drop box. Please follow all instructions carefully to ensure that your transaction can be processed without undue delays.
