Well, not 100% correct, but pretty close. ALL CPD stations have both numbers AND names. According to department directives, dispatching is supposed to be done by beat or unit numbers. I work in the 10th (Ogden) District. The dispatchers are supposed to call me by my beat number (1011) but sometimes they'll call us using the old "Marquette" signature, e.g. Marquette-11.
The 011th District has been located at Harrison and Kedzie since 1976, having previously been on the corner of Fillmore and Pulaski. Even though it's been 35 years, everyone still sticks to calling the 011th District cars "Fillmore-21", for example.
Back in the old days, District stations bore the names of the community that station served. "Lawndale," "Kensington," "Brighton Park" and "Pullman." I guess they got bored and started using the name of the street the station was built on. Wentworth, Monroe and Ogden are awful names and lack character.
Below is a list of all 25 police districts and their respective name.
