Question: 311 is Chicago s web and phone portal for government in formation

311 is Chicago’s web and phone portal for government in-formation and nonemergency services. 311 serves as a comprehensive one- stop shop for residents, visitors, and business owners; therefore, it is critical that 311 representatives answer calls and respond to requests in a timely and accurate fashion.
