Address Services

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 confusion for visitors to our community.

If you have questions or concerns about your physical address, need to obtain a new physical address, or change your current physical address please contact us.
