About Cambodia Calling Code
Every country has a unique international dialing prefix; for Cambodia it is +855. The ITU assigns these codes under recommendation E.164. Dial +855 after your country's exit code, then the local subscriber number. Cambodia is in Asia.
Cambodia is known locally as KΓ’mpΕchΓ©a β Phnom Penh is the capital. When saving an international contact, write the number in full international format with +855 so it works from any country.
The ITU-T E.164 recommendation standardizes international numbering, giving every country and territory a distinct prefix. Without the correct prefix, international calls cannot be routed to the right destination.
Where the +855 Calling Code Is Used
The country code +855 is assigned to Cambodia, located in South-Eastern Asia, with the capital Phnom Penh. This code is part of the international telephony numbering plan and is used for all calls made to Cambodia from outside the country.
A number displayed as +855 β¦ is in international format: +855 replaces the domestic trunk prefix. From abroad, always drop any leading 0 of the area code and dial +855 + area code + subscriber number.
Calling codes starting with 8 are part of the ITU's regional numbering plan for the area around Cambodia, in South-Eastern Asia. When saving Cambodia numbers internationally, write +855 followed by the area code without its leading 0 β this format works from every country.
Cambodia Phone Number Formats
Numbers in Cambodia use the standard E.164 pattern β +855, then the area code, then the subscriber number. The same layout applies to landlines and mobile phones:
π± Number Structure
- International format: +855 [area code] [subscriber number]
- From abroad: exit code + +855 + local number (drop the trunk prefix 0)
- Within Cambodia: dial the local number directly
In most countries, domestic numbers start with a trunk prefix (often 0) that must be omitted internationally: dial your exit code, then +855, then the local number as written without its leading zero.
Time Zone in Cambodia
Cambodia runs on Asia/Phnom_Penh, which is UTC+07:00 UTC. Schedule international calls accordingly β a convenient time for you may be very early or very late there.
Use the UTC offset (UTC+07:00) to plan calls to Cambodia. For most international callers, the practical rule is: schedule business-hour calls to Phnom Penh during the overlap between your working day and theirs.
Daylight saving time can shift Cambodia's clock by one hour in summer. For time-critical calls, confirm the current UTC offset rather than relying on the standard value.
