Call 311 for assistance with non-emergency City Services and for information on events, programs and agencies within the City of Chicago.

The new CHI 311 system brings unprecedented levels of openness, innovation and accountability to the delivery of City services. We’ve reinvented and reinvigorated City service delivery by building a new 311 system with Chicagoans for Chicagoans. 

With the new CHI 311 website and mobile app, you can create new service requests; check the status of existing requests and the time it will take to resolve; snap a photo and submit it with a request to improve accuracy; map requests to help pinpoint a location; create an account to track service requests and get local, relevant information; provide feedback upon completion; and search and see helpful knowledge articles and search other requests in your neighborhood.

The free CHI 311 mobile app is available for both iOS and Android devices and may be downloaded in the Apple App Store or Google Play.
