What Are Postal Codes and Why Are They Important?

Postal codes, also known as ZIP codes in some countries, are alphanumeric sequences assigned to specific geographic areas to streamline mail sorting and delivery.

These codes play a vital role in:

  • Organizing mail for efficient routing
  • Reducing delivery errors
  • Enhancing tracking for parcels and packages
  • Facilitating automation in mail processing

In Cambodia, where many areas still rely on manual delivery, the inclusion of a postal code significantly improves the accuracy and timeliness of mail and package delivery.


Overview of Cambodia’s Postal Code System

Cambodia uses a 6-digit postal code format, introduced to standardize mail distribution across all provinces and municipalities.

The structure is as follows:

  • The first two digits represent the province or autonomous municipality.
  • The next two digits indicate the district.
  • The last two digits refer to the commune or a specific delivery area.

Compared to countries like the United States (ZIP+4 format) or the UK (alphanumeric), Cambodia’s system is simpler but still highly functional for its current needs.

Example Format:

ProvincePostal Code Prefix
Phnom Penh12xxxx
Siem Reap17xxxx
Battambang02xxxx
Sihanoukville18xxxx
Kampong Cham03xxxx

The Cambodia Post (https://www.cambodiapost.post) is actively working to increase adoption and accuracy of postal codes, particularly in rural areas where addressing can be inconsistent.
