Peru Postal Codes

In February 2011, for the first time in history, Peru's Ministry of Transport and Communications inducted postal codes (zip codes) for the entire country, and in 2016, the Ministry rolled out an even bigger postal code system. Before this, postal codes (códigos postales in Spanish) were used only for Lima and Callao. Now, with the establishment of the Código Postal Nacional (CPN), Peru has a nationwide system of more than 2,700 postcodes.

The current Peruvian postal code system uses five numbers. The first two numbers signify the administrative region of Peru in which the address is located (see table below). The next three numbers represent smaller areas within each administrative region, which may include provinces but can vary depending on the population density of any given area.

All included, the current Peruvian postal code system features a total of 2,670 postal codes in 210 “postal zones” across the nation’s 25 administrative regions. Although finding the full postal code used to be difficult, the Peruvian Ministerio de Transporte y Comunicaciones website offers some useful resources for understanding the postal system, including several ways to look up the postal code for different regions of the country.

Finding the Correct Peruvian Postal Code

All you have to do to find the postal code for your destination is enter the city name into the search bar on the official Peru Postal Code Finder. Operated by Codigo Postal Peru, the Postal Code Finder is now an official service of the Peruvian Ministry of Transportation and Communications. 

The Peruvian postal system isn’t flawless (things can and do disappear from time to time), but the usage—or not—of postal codes is unlikely to make a great difference. As a result, one option is to simply not include it in the address if you can’t find the correct postal code.

In fact, many Peruvians, especially those outside Lima and Callao, still post letters and packages without including postal codes. For example, the city of Tarapoto commonly receives post from various countries (including the United States); and the arrival success rate is about 95 percent—with the absence of postal code.
