All the taxis are yellow, they have the "Taxi" sign above and the operation license and tariffs on the doors, outside. The tariff is from 1.39 Lei/km (generally) up to 3.5 Lei/km if you are in an expensive car.
There is an initial tariff for departing which is equal to the tariff per km. All taxis have electronic meters and the driver must start the meter as soon as they depart. If they don't start it, then you should not continue the ride. Our recommendation is to use a taxi only if you must to do that and to pay attention to the tariff written on the driver or passenger door.
Below you will find some of the major taxi companies operating in Bucharest.
