About Denver's 311 Call Center

Denver 311 exists to increase the level of citizen satisfaction when contacting the City and County of Denver. Denver 311 provides a centralized repository for information relating to citizen issues and agency process and procedures.

Our contact center provides state-of-the-art multi-channel communication paths to the citizen, including voice, electronic, walk-up, and web-enabled self help mediums. By offering insight into ways to improve city government through accurate and timely measurement, our hope is to build a superior 311 center that can be used as a benchmark by local government.

Our goal is to help agencies improve service delivery by allowing them to focus on core missions and manage workload in an efficient and timely manner.


The City & County of Denver is a proud recipient of the Public Technology Institute’s
Citizen Engaged Community Award
