Peruvian addresses turn on the district (distrito), not the postal code, which is often left blank. Lima runs two postal systems at once: a modern 5-digit code and the legacy LIMA NN format. Here is the correct structure, a real example, and the mistakes that cause returns.
A Peruvian label runs recipient, the street with its type and number, the district, then the province with the 5-digit code when available, and the country.

Routing runs on the district and province, so those fields carry the delivery while the code, when present, refines it.
The country-specific rules that generic autocomplete and single-line address fields tend to get wrong.
Serpost uses a 5-digit national code (15001 for central Lima, the first two digits the region). The older Lima system wrote LIMA 23, where the number is the district zone. You will see both, so validate against whichever the address uses.
In Lima and other cities the district (Cercado de Lima, Miraflores, San Isidro) is the primary local routing unit. A checkout that omits a district field produces addresses couriers cannot place.
Peruvian streets carry a type prefix: Jr. (jirón), Av. (avenida), Calle, or Psje. (pasaje). Dropping it can make a jirón and an avenida of the same name ambiguous.
Many Peruvian addresses ship without a postal code at all; Serpost and private couriers route on district, province and street. Include the code when you have it, but the district and province carry the delivery.
Each of these passes a basic "is this field filled in" check but fails at the carrier, turning into a redelivery, a return, or an address correction fee.
