Format of Argentine Postal Codes

The Argentine Postal Code (Código Postal Argentino, CPA) plays a crucial role in the efficient distribution of mail throughout Argentina. Comprising eight alphanumeric characters, it is structured into three distinct parts:

Province Reference: The first character of the CPA is a single letter denoting the province or autonomous city. For example, "C" signifies Capital Federal (Autonomous City of Buenos Aires), while "Q" represents Neuquén Province.
Town or City Identification: Following the province reference, the CPA includes four digits pinpointing the specific town or city within the province or autonomous city.
Block Location: The final three letters of the CPA identify the side of the city block where the address is situated.

The first letter in the CPA, representing the province or autonomous city, originates from the former Argentine license plate system, with each province typically assigned a letter corresponding to its initial letter.

The four-digit segment of the CPA corresponds to various regions within Argentina. For instance, provinces are often grouped as follows:

1XXX = Buenos Aires City, Buenos Aires Province North
2XXX = Santa Fe Province
3XXX = Santa Fe, Entre Ríos, Chaco, Corrientes, Formosa, Misiones Provinces
4XXX = Jujuy, Salta, Tucumán, Catamarca, Santiago del Estero Provinces
5XXX = Córdoba, La Rioja, San Juan, San Luis, Mendoza Provinces
6XXX = Buenos Aires Province West, La Pampa Province
7XXX = Buenos Aires Province East, Center, and South
8XXX = Buenos Aires Province South, Río Negro, Neuquén Provinces
9XXX = Chubut Province, Río Negro, Santa Cruz Provinces, Tierra Del Fuego

History of Argentine Postal Codes

Argentina implemented its initial four-digit postal code system in 1958 to streamline mail distribution. Until 1998, each municipality was assigned a unique four-digit postal code, with the first digit indicating a region within the country. These codes laid the foundation for the subsequent CPA system.

Implementation of the CPA System

The official launch of the CPA system in 1998 marked a significant advancement in the accuracy and efficiency of mail delivery in Argentina. Each of Argentina's 23 provinces and the autonomous city of Buenos Aires has its own set of postal codes to comprehensively cover its territory. While the use of CPA is not mandatory for private individuals, companies conducting mass mailings enjoy discounts when utilizing CPA. However, widespread adoption of CPA among private individuals remains limited. Even government agencies and private businesses often list only the base code (the old system).
