📲 How to Call Cambodia from Abroad
Follow these 4 simple steps to dial any phone number in Cambodia:
1
Dial your international access code
Most countries use 00 or +. From mobile phones, the + symbol works worldwide.
2
Dial Cambodia's country code: +855
Dial +855 immediately after the international access code. Do not include the + again if you already used 00.
3
Dial the city or area code
For landlines, dial the city code (drop any leading 0). For mobile numbers, skip this step.
4
Dial the local phone number
Enter the remaining digits of the recipient's phone number to complete the call.
💡 Example: To call Baghdad from the US, dial 011 +855 1 [number]. From mobile: + +855 1 [number].

How to Call Abroad from Cambodia
To call another country from Cambodia: dial the international exit code (00 in most countries, or press and hold 0 on a mobile to get +), then the destination country code, then the area code (without its leading 0), then the number. Example: to call the US, dial 00 1 [number] or + 1 [number].
International Number Format (E.164)
The global standard format for Cambodia numbers is +855 followed by the national number without its leading 0. A full international number has at most 15 digits including the country code. Save all your contacts this way so they work from anywhere in the world and in every app.

Why Isn't My Call Connecting? Common Fixes

You forgot the country code +855 — it must come right after the exit code.

Common Questions About Calling Cambodia
When should I use + instead of 00?
The + symbol works from any mobile phone anywhere in the world and replaces each country's exit code, so you never need to memorize them. 00 is the most common exit code and works on both landlines and mobiles. On a mobile, always prefer + — it is the most reliable.
Why do I drop the leading 0 of the area or mobile code when calling from abroad?
The leading 0 is a national trunk prefix used only for domestic calls. When calling internationally, the country code +855 takes its place, so you remove that 0 — otherwise the number is wrong and the call fails.
How do I call a mobile versus a landline in Cambodia?
For a mobile: dial +855 then the mobile number without its leading 0. For a landline: dial +855, then the city code (without its leading 0), then the local number. Mobile numbers never need a city code.
How do I send a text message (SMS) to Cambodia from abroad?
Save the number in international format — +855 then the number without its leading 0 — and send your message as usual. Your carrier may apply international SMS charges.
How can I call Cambodia via WhatsApp?
Add the contact in international format — +855 then the number without its leading 0. If they have WhatsApp, they appear automatically. WhatsApp calls run over the internet, are free, and need no exit code.
How much does it cost to call Cambodia?
It depends on your carrier and the line type; international calls over the regular phone network can be expensive. To save money, use internet apps like WhatsApp or Viber, or get a local SIM or eSIM.
What does the code +855 mean and where does it come from?
+855 is the international dialing code assigned to Cambodia by the International Telecommunication Union (ITU). Every country has a unique code that identifies it on the global telephone network.
How do I save a Cambodia number in the correct international format?
Always store it in E.164 format: +855 then the national number without its leading 0 and without spaces. Saved this way, it works from any country and in every app without changes.
