If you don’t have the medallion number or the garage information is not found in the TLC Lookup tool, the Taxi and Limousine Commission (TLC) will try to identify your taxi using the time and location of your trip.
During Business Hours
Monday to Friday from 8:30 AM to 4 PM, the NYC311 Call Center will transfer you to TLC. TLC will ask for details about your trip and your lost item to try to figure out which taxi you took. If they can figure it out, they will give you contact information for your taxi's garage. Then you can call the garage to see it they have your item and arrange to pick it up.
Call 311 to report the problem during hours.
After Business Hours and Holidays
On weekends, holidays, and Monday to Friday from 4 PM to 8:30 AM, you can file a Service Request. TLC will usually act on it within two business days. If they are able to figure out which taxi you took, they will update the Service Request with contact information for the taxi's garage. Then you can call the garage to see it they have your item and arrange to pick it up.
