If you believe a car or vehicle is abandoned (e.g. has not moved in over 10 days), first contact your neighbors as they might know who it belongs to. If no one knows who owns the vehicle, then call 911 to register it as abandoned. Be prepared to give them the following information on the vehicle:
- exact address where it is located
- make (brand)
- license plate number, noting if the sticker is expired
- Chicago vehicle/city sticker if displayed, noting if it is expired
- Dangerous conditions such as broken window, flat tire, damaged body
If your vehicle is missing from the street, you can check to see if it was towed or relocated by the City of Chicago through this link. If you feel your vehicle was stolen, call 311 to file a police report (more info).
