3 Ways to Renew Your Vehicle Registration

Renewal postcards are mailed out right before the month of expiration. In Colorado, you can renew up to the last day of the month after expiration (known as the one-month grace period) without accruing late fees. However, we recommend that you do not travel out of state on expired tags as other states may not honor the grace month.

Available 24/7

Sticker arrives by mail in 1-2 weeks.

Tag expires in less than 2 weeks? Don’t worry! You will receive a temporary permit to print and place on your front dash in the meantime.
