How to call Cambodia (country code +855)

Calling to Cambodia

Cambodia’s country code may be mis-labelled:

  • Country code 00855 (exit code of ’00’ used in many European, Asian, and African nations followed by Cambodia’s country code of ‘855’).
  • Country code 011855 (exit code of ‘011’ used in the United States and Canada followed by Cambodia’s country code of ‘855’).

When calling to a mis-labelled country code, remove the exit code from the call sequence and replace it with the exit code of the country the call is dialed from.

… to a mobile (cellular) phone

Use the same call sequence.

Cambodian mobile phone numbers have their own area codes, however there is no pattern to area codes designated for mobile phones. Each area code is specific to the mobile carrier.

When calling a mobile phone user, call to the country where the mobile phone is registered, regardless of where the person being called is currently roaming.

… to a VoIP phone

VoIP phone numbers based in Cambodia are accessed with the same call sequence as a regular landline phone.

There are no designated VoIP exchanges in Cambodia.

When calling a VoIP phone user, call to the country where the VoIP phone is registered, regardless of where the person being called is currently roaming.

… to a satellite phone

Cambodia does not have a country-speicifc satellite phone system.

Most satellite phones operate on their own country code – calls to these satellite phones follow their own call sequence.

… sending a fax

Use the same call sequence.
