We explain what the postal code is, what it is used for and what its origin was. In addition, some examples of postal codes.
What is the postal code?
Postal codes are series of digits and letters that are used to designate a specific geographic region of a country, and thus quickly identify the destination of postal shipments (i.e. traditional mail), or to find addresses in global positioning systems (GPS). Each country has its own system of codes with which it identifies its regions, cities and even parts of the same city.
Postal codes are usually assigned to specific locations, although some organizations that receive large amounts of mail, such as government agencies, large companies or media outlets, may have their own. Either way, these codes are added to the written address of the destination, and allow for quick sorting of mail. You must read about Blood Moon or Red Moon once.
Some places do not have postal codes, as their territories are not large enough to justify one. This is the case, for example, in Gibraltar and Hong Kong.
Origin of postal codes
Modern postal codes emerged in Soviet Ukraine (part of the USSR) in 1932. This first system used the administrative segments into which large cities were divided, assigning each a pair of identifying digits. It was published in a 268-page document, in the then Ukrainian capital of Kharkiv, under the name “List of postal establishments, railway stations, cities, towns and rural councils of Ukraine with their designated postal codes”.
Although the Ukrainian pioneer system was abandoned in 1939, at the beginning of World War II, similar versions emerged throughout the 20th century in various European and American nations, such as Germany (1941), Argentina (1958), the United Kingdom (1959), the United States (1963) and Switzerland (1964), pioneers in postal organization in the world. Nations such as Spain had to wait even longer, until the mid-1980s. Maybe you should definitely read about Winter once.

Postal codes of Brazil
Postal codes in Brazil were created in 1971, with an initial structure of five digits, which due to the sustained growth of the population proved inefficient. Then it was reformulated to include eight digits, according to a 5-3 structure, that is, five digits in a row, a hyphen and then three more digits.
The first number of this postal code represents each of the ten postal zones into which the Brazilian territory was divided, starting in the city of São Paulo and moving counterclockwise toward the rest of the country. This classification is given as follows:
