Código de Endereçamento Postal (Postal Addressing Code) is the Brazilian postal code system commonly known as CEP. Introduced in 1972 as a sequence of five digits, it was expanded to eight digits in 1992 to allow for more precise localization. The standard format is "nnnnn-nnn" (the original five digits, a hyphen, and the new three digits). Most cities with population around 100,000 and above have a CEP assigned to every public place and to some high-occupancy private spaces, like major commercial buildings and large residential condos. Small towns are assigned a general 5-digit code followed by the suffix -000. More information...
