In New York City, taxicabs come in two varieties: yellow and green; they are widely recognizable symbols of the city. Taxis painted yellow are able to pick up passengers anywhere in the five boroughs. Those painted apple green, which began to appear in August 2013, are allowed to pick up passengers in Upper Manhattan, the Bronx, Brooklyn, Queens, and Staten Island. Both types have the same fare structure. Taxicabs are operated by private companies and licensed by the New York City Taxi and Limousine Commission (TLC). It also oversees over 40,000 other for-hire vehicles, including "black cars", commuter vans, and ambulettes.

A taxi, also known as a taxicab or simply a cab, is a type of vehicle for hire with a driver, used by a single passenger or small group of passengers, often for a non-shared ride. A taxicab conveys passengers between locations of their choice. This differs from public transport where the pick-up and drop-off locations are decided by the service provider, not by the customers, although demand responsive transport and share taxis provide a hybrid bus/taxi mode.
