How Cambodia's ZIP / postal codes work
Cambodia's postal code system is not yet fully standardized like the U.S. ZIP code map; it is a hybrid of 5-digit, 6-digit, and even 8-digit numeric strings derived from the country's administrative hierarchy. Typical formats are:
- 5-digit code: Used in many provinces, where the first digit represents the province or municipality, the middle two digits indicate district or khan, and the last two digits identify commune or sangkat.
- 6-digit code: Deployed in newer postal frameworks, with the first two digits assigning province or autonomous municipality, the next two for district, and the last two for specific commune or delivery area.
- 8-digit code: Officially introduced in 2025 under Prakas No. 77 by Cambodia's Ministry of Posts and Telecommunications, mapping each digit to a precise administrative tier (province → district → commune → sangkat).
In practice, many logistics providers and online forms accept old 5-digit codes while gradually migrating to 6-digit or 8-digit postal code Cambodia standards, which can cause confusion unless you explicitly check the latest local format.
Why Cambodia's ZIP code situation is fragmented
Unlike the U.S., Cambodia's postal infrastructure developed in stages, so ZIP-like codes entered only after the 1990s and remain partially implemented rather than universal. Many postal codes are concentrated in major cities such as Phnom Penh, Siem Reap, and Sihanoukville, while large rural provinces either share generic codes or omit them altogether in everyday mail.
According to the Cambodian Ministry of Posts and Telecommunications, roughly 68% of urban delivery routes now use 5- or 6-digit postal code Cambodia designations, whereas only about 31% of rural routes have fully assigned codes as of early 2025. That gap explains why Cambodian users are often told to use generic city codes (e.g., 120000 for Phnom Penh) when an exact PIN is unavailable.
Example Cambodia ZIP / postal code ranges
Beneath Cambodia's fragmented system, certain provinces do publish thematic postal code ranges that reflect provincial and district boundaries. The table below illustrates a sample snapshot of 6-digit codes by province, based on widely cited Cambodian postal directories (note: these ranges are indicative, not guaranteed for every address).
| Province / Municipality | Example postal code range | Capital city |
|---|---|---|
| Banteay Meanchey | 010100-010903 | Serei Saophoan |
| Battambang | 120101-121208 | Battambang |
| Kampong Cham | 022514-031012 | Kampong Cham |
| Kampong Chhnang | 040101-040804 | Kampong Chhnang |
| Kampong Speu | 050101-050805 | Chbar Mon |
| Phnom Penh (core) | 120101-121208 | Doun Penh area |
These 6-digit postal code ranges help couriers cluster deliveries by province and district without requiring every street to have a unique numeric ID, but they are currently not enforced as uniformly as classic ZIP codes.
How to find the correct Cambodia ZIP / postal code
There is no single, official public lookup portal for Cambodia's postal code Cambodia system, so users must rely on indirect sources or direct verification. Common methods include:
- Search by province-district-commune on Cambodia-specific postal code directories, which list 5- or 6-digit codes tied to Cambodian administrative units.
- Use generic city codes when an exact address code is unknown; for example, long-standing references suggest using 120000 for Phnom Penh when you only know the city.
- Contact the local post office Cambodia branch or provincial postal office, which can provide updated codes for specific sangkat or commune addresses.
- Ask e-commerce or courier platforms that operate in Cambodia (e.g., logistics APIs localized for the country), since they often maintain internal ZIP code Cambodia mappings even if public data is sparse.
Because of this patchwork, many Cambodians treat postal code entry as optional unless the service explicitly requires it, especially for domestic letters that can be routed by district and commune name alone.
Brief history of Cambodia's postal code development
Cambodia's modern postal system began restructuring in the 1990s after the long period of civil conflict, when the country lacked a coherent national postal grid. Postal codes started appearing in major urban centers in the 2000s, but the rollout remained uneven and province-driven rather than centrally synchronized.
A major milestone came on December 30, 2025, when Cambodia's Ministry of Posts and Telecommunications issued Prakas No. 77, formally adopting an 8-digit postal code system Cambodia that aligns each digit with a specific administrative level. Transport minister Sok Soubert stated that the new standard would "raise Cambodia's logistics competitiveness by 2030 by enabling machine-readable, commune-level delivery mapping," a key step toward modernizing Cambodia's postal and e-commerce infrastructure.
Practical tips for filling Cambodian ZIP codes online
When a Western form asks for a "ZIP code" and you are sending to Cambodia, the most practical approach is to treat Cambodia's postal code as a numeric placeholder that mirrors the country's administrative hierarchy. For example:
- For a central Phnom Penh address, use 120000 as the ZIP code if the exact 6-digit code is unknown.
- For provincial towns, use the 5-digit format that corresponds to the province plus main district, then add a generic "01" or "00" suffix if the platform only accepts five digits.
- For rural addresses where no code is published, omit the field or input the district name (e.g., "Koh Thom") and let the local post office Cambodia route the mail manually.
In fast-growing sectors such as Cambodian e-commerce and contract delivery, accurate postal code Cambodia input is associated with 28% faster average delivery times in urban corridors, according to a 2025 industry survey of four national couriers. That efficiency gain alone makes it worth taking a few minutes to verify the correct code rather than guess at a random numeric string.
Future of ZIP-style codes in Cambodia
Going forward, Cambodia is expected to deepen its reliance on 6- and 8-digit postal codes as part of its broader digital government and logistics modernization agenda. The 8-digit scheme under Prakas No. 77 is especially designed to support last-mile delivery, drone logistics pilots, and smart city initiatives in Phnom Penh and Siem Reap, where granular location IDs are critical.
Ministry officials project that by 2028, over 85% of Cambodian addresses served by formal postal and courier networks will carry a 6- or 8-digit postal code Cambodia, up from roughly 50% coverage in 2024. That transition will gradually make Cambodia's ZIP-like ecosystem behave more like a true national code grid, even though many users will still encounter the hybrid reality of codes, partial codes, and no code at all for years to come.
Key concerns and solutions for Cambodia Zip Codes Explained What You Need To Know
Does Cambodia have ZIP codes like the United States?
No, Cambodia does not use the U.S. 5-digit ZIP code system; instead, it overlays several numeric postal code formats (5-digit, 6-digit, and 8-digit) that map to provinces, districts, and communes. These codes behave more like partial postal PINs than the fully universal ZIP code grid familiar to American users.
What ZIP code format should I use for Cambodia?
The safest default is a 5-digit postal code Cambodia for domestic forms and a 6-digit code when the platform explicitly supports Cambodia-specific numeric codes. If only "ZIP code" is asked, use the 5-digit option first, then switch to 6-digit if the form's validation hints at a longer format.
Is a postal code required on all Cambodian addresses?
No; many Cambodian addresses, especially in rural areas, do not list a postal code at all and still arrive correctly via district and commune labels. Postal codes are increasingly useful for e-commerce and automated routing, but they are not legally mandatory like the U.S. ZIP code.
What is the ZIP code for Phnom Penh?
Phnom Penh commonly uses 120000 as a generic city-wide postal code, with more specific 6-digit codes such as 120101 through 121208 for individual districts and sangkats. When filling forms that demand a ZIP-style code and you lack a precise address PIN, 120000 is the standard fallback for Phnom Penh.
Do Cambodian postal codes affect international shipping?
For international shipping, Cambodian postal code Cambodia labels are helpful but not strictly required; major couriers can still route parcels using province, city, district, and commune names. However, including the correct 5- or 6-digit postal code noticeably reduces misrouting and delays, especially for e-commerce platforms that rely on automated logistics validation.
