Postal codes in Argentina
Postal codes in Argentina are called códigos postales. Until 1998[1] Argentina employed a four-digit postal code for each municipality, with the first digit representing a region in the country, except in the case of the city of Buenos Aires (which had different postal codes starting in 1000 and with the other numbers varying according to the zone). The unique codes became the base for the newer system, officially called CPA (Código Postal Argentino, Argentine Postal Code).[2]
The CPA consists of three parts:[3]
- A single letter that encodes the province (for example, C for Capital Federal, Q for Neuquén).
- Four digits (the old postal code or a variation of it on the last digits) showing the municipality.
- Three letters, identifying a side of the block where the address is located.
The CPA is not mandatory for private use, but companies that do mass mailings are benefited with discounts if they use the CPA. Despite this, the CPA is still not in wide use by private persons, and even government sources and private businesses often list the base code as in the old system. In order to ease the adoption of the new postal code, the former state mail company (Correo Argentino) provides a look-up feature on its website.[4] The CPA is intended to improve the quality and speed of mail delivery, but mail without a well-formed CPA will be delivered correctly as well.
This change can be compared with the ZIP+4 movement in the United States, in which the last four digits identify the block of the address.
The first letter in the CPA, which identifies the province, has its origins in the old Argentine license plates system, which gave each province a letter, usually its initial. Since several provinces share the same initial, a few odd assignments are found (such as X for Córdoba, A for Salta, and N for Misiones). See ISO 3166-2:AR for a complete list.
The four digits could be grouped as the following:
- 1XXX = Buenos Aires City, Buenos Aires Province North (EG: C1420 Buenos Aires City, B1900 La Plata).
- 2XXX = Santa Fe (EG: S2000 Rosario, S2300 Rafaela).
- 3XXX = Santa Fe, Entre Ríos, Chaco, Corrientes, Formosa, Misiones (EG: E3100 Paraná, P3600 Formosa, N3700 Posadas, W3400 Corrientes).
- 4XXX = Jujuy, Salta, Tucumán, Catamarca, Santiago del Estero (EG: T4000 Tucumán, A4400 Salta, K4700 Catamarca).
- 5XXX = Córdoba, La Rioja, San Juan, San Luis, Mendoza (EG: X5000 Córdoba, M5500 Mendoza, D5700 San Luis, F5300 La Rioja).
- 6XXX = Buenos Aires Province West, La Pampa (EG: B6600 Junín, L6900 Santa Rosa).
- 7XXX = Buenos Aires Province East, Center and South (EG: B7000 Tandil, B7600 Mar del Plata, B7400 Olavarría).
- 8XXX = Buenos Aires Province South, Río Negro, Neuquén (EG: B8000 Bahía Blanca, R8400 Bariloche, R8500 Viedma, Q8300 Neuquén).
- 9XXX = Chubut, Santa Cruz and Tierra del Fuego (EG: U9000 Comodoro Rivadavia, U9200 Esquel, V9410 Ushuaia, Z9400 Río Gallegos).
