Pitkin County is dedicated to maintaining the most correct address information for parcels and addressable structures. Incorrect physical addresses not only result in delays by emergency services (fire, ambulance, law enforcement), they impede services provided by telephone, cable, gas, and electric providers, can add expense, and delays in delivering packages, and may cause directional confusion for visitors to our community.
This page provides information and links for the public to help get you to the right place if you have questions or concerns about your PHYSICAL address, including how to obtain a update or add a new physical address. We have authority over all addressing in unincorporated Pitkin County.
