House Numbering - Latin America

Latin America

Some countries in Latin America use systems similar to those in Europe. Houses are numbered in ascending order from downtown to the border of the city. In Mexico, the cities are usually divided in Colonias, which are small or medium areas. The colonia is commonly included in the address before the postal code. Sometimes when houses merge in a street or new constructions are built after the numbering was made, the address can become ambiguous. When a number is repeated a letter is added to the newest house. For example, if there are two 35's, one remains as 35 and the second one becomes 35A or 35Bis.

It is sometimes common that in remote towns or non-planned areas inside the cities that the streets do not have any name and the houses do not have numbers. In these cases the address of the houses are usually the name of the person or family, the name of the area or town, and "Dirección Conocida" (Known Address), which means that the house of the family is known by almost all the community. This kind of addressing is only used in remote towns or small communities near highways.

For people living near highways or roads the usual address is the kilometer of the road in which the house is established; if there's more than one, some references might be written or the "Dirección Conocida" may be added. In countries like Brazil and Argentina, but also in some villages in France, this scheme is used also for streets in cities, where the house number is the distance, measured in meters, from the house to the start of the street.
