Peru Postal Codes

Peru Postal Codes

If you are filling out a Peru address, use the 5-digit postal code when you can. Peru’s postal codes are not just city labels, so guessing one for “Lima” is risky. Lima has many districts, and the code should match the district or delivery zone, not only the city name.

A realistic Lima address would look like this: Avenida Larco 812, Miraflores, 15074 Lima, Peru. For central or well-known Lima districts, codes starting with 15 are common, but 15074 is not a general code for all of Lima. San Isidro, Barranco, Surco, Cercado de Lima, and Callao can all use different codes even when the address feels close on the map.

A soft way to read Peru codes is this: Lima-area addresses often begin with 15 or nearby numbers, Callao often appears separately, and other regions such as Arequipa, Cusco, La Libertad, Piura, or Junín have their own starting ranges. That is useful for spotting obvious mistakes, but it is practical guidance, not an official street-by-street rule.

Peru’s official postal code lookup at codigopostal.gob.pe is the best place to check the exact code when you know the district or street, and UPU-style addressing guidance for Peru also treats the postal code as part of the address rather than a loose city shortcut.

So if a form only gives you “Lima,” do not automatically type the first Lima code you find. Look for the district first. In Peru, “Miraflores, Lima” and “Cercado de Lima” are not the same postal-code decision, even if both are normal Lima addresses.
