Argentina Post Codes Explained

Argentina's postal system may seem complex, but understanding post codes can make a big difference in sending and receiving mail. The country's post codes, also known as Códigos Postales, are a series of numbers and letters that help identify a specific location.

Argentina has a total of 22 post codes, each corresponding to a different province. The post code system was introduced in 1998 to improve mail sorting and delivery efficiency.

The post code format in Argentina consists of a combination of letters and numbers, usually in the format of "XXXXX-XXXX" or "XXXXX XXXX". This format helps postal workers quickly identify the destination of a letter or package.

Each post code in Argentina is unique and corresponds to a specific geographic area, making it easier to locate a specific address.

Argentina's postal code format changed in 1999 from 4 digits to 8 characters. The first character cannot be I, O, or V.

The new codes cover smaller areas, with the first five characters being the prefixes and the last three being the suffixes. This change allows for more precise mail delivery.

The letter at the start of the prefix indicates the province. This is a significant improvement over the previous system, which only used the first digit to represent a region.

The suffix identifies the buildings within the zone, making it easier to find specific addresses. This level of detail was not possible with the older four-digit system.
