Describe your compliment.
For Green Taxis, enter the permit number in the description field. This is the 5-letter/number combination located on the taxi receipt, on the side of the taxi, and on the partition in the taxi.
For livery or black car services, leave the Taxi Medallion # field blank. If you do not have the TLC Driver License Number, include the vehicle plate number in the description field. This will be very helpful in identifying the driver.
