Peru Postal Codes

How to Find the Famously Unfindable 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. 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. These may be provinces but can vary depending on the population density of any given area.

Finding the Correct Peruvian Postal Code

Finding the full postal code can be difficult. The Peruvian Ministerio de Transporte y Comunicaciones website used to offer two resources to help find the correct five-digit postal code, but both seem to have been abandoned and no longer work.

An alternative option is CodigoPostalPeru.com, which seems to function quite well as long as you can work out where exactly you want to send your letter or package, which can be more complicated than you'd imagine.

If you can’t find the correct postal code, one option is to simply not include it in the address. Many Peruvians, especially those outside Lima and Callao, still post letters and packages without including a postal code.

The Peruvian postal system isn’t flawless (things can and do disappear from time to time), but the usage -- or not -- of a postal code is unlikely to make a great difference. For example, the city of Tarapoto commonly receives post from various countries (including the USA and the UK); and the arrival success rate is about 95 percent -- with the absence of a postal code.

Would the inclusion of a postal code raise the arrival rate to 100 percent? Probably not, but as Peruvians become increasingly comfortable with postal codes, this may not be the case in the future.
