The Unified Vehicular Volume Reduction Program (UVVRP), commonly called number coding or color coding, is a road space rationing program in the Philippines that aims to reduce traffic congestion, in particular during peak hours, by restricting the types of vehicles that can use major public roads based on the final digit of the vehicle's license plate. First implemented in 1995 in Metro Manila, the similar programs has also been implemented in the cities of Baguio, Cabanatuan, and Dagupan and the province of Cavite.
