Postal codes (also known as ZIP codes) are sequences of characters consisting of numbers, letters, or a combination of both, used to identify geographic areas within a country’s postal system, enabling faster, more accurate, and more efficient sorting, processing, and delivery of mail, parcels, and goods, while also playing an important role in fields such as e-commerce, logistics, and transportation services.
Early mail sorting systems were primarily based on place names and transportation routes. By the 19th century, as trade and transportation expanded rapidly, many large cities began dividing their territories into smaller postal districts to improve the efficiency of mail sorting and delivery. These early practices laid the groundwork for modern postal code systems, although it was not until the mid-20th century that such systems were widely implemented at the national level.
In 1941, Germany became one of the first countries to introduce a nationwide postal code system (Postleitzahl). From the 1960s onward, this model gradually became a global standard, as more countries developed and refined their own postal code systems to suit their geographic characteristics and transportation networks.
In Vietnam, the postal code system was officially introduced in 2004 in accordance with guidelines from the Universal Postal Union.

3. Vietnam Postal Code Structure
The national postcode consists of five numeric digits (1-5). Each digit or group of digits identifies a different administrative level:
• The first digit identifies the regional code.
• The first two digits identify the province or centrally governed city.
• The first three digits identify the district or equivalent administrative unit.
• All five digits together identify the specific postcode-assigned entity.
Entities assigned a postcode include:
• Communes, wards, and equivalent administrative units
• Public postal service points within the national postal network
• Postal service points and service units of the special postal network serving the Communist Party of Vietnam and the State of Vietnam, as designated by the Prime Minister
• Foreign diplomatic missions and consulates
• Representative offices of international organizations located in Vietnam
This structure allows each postcode to clearly identify the region, province or municipality, district-level unit, and the specific postal service location or administrative unit.
