Mobiles start with 0 and a 2-digit operator code, like 012 or 016. The 0 is dropped from abroad, so 012 345 678 becomes +855 12 345 678.
Mobile numbers: In the national plan, mobiles start with 0 plus a 2-digit operator code such as 012 and have 9 digits locally: 012 xxx xxx, or +855 12 xxx xxx from abroad. An example in international format: +855 12 xxx xxx.

Calling out of Cambodia. From a landline there, start with 001 (the exit code can depend on the phone company), then the other country's code and number. From a mobile, + works everywhere.
Time in Cambodia. Cambodia is on GMT+7 all year. Check the time before you call, especially for business numbers.
Area codes are given by province: Kandal is 24, but Takhmau in Kandal counts as part of Phnom Penh and uses 23.
Landline numbers have 6 digits after the 2-digit area code, so a Phnom Penh landline looks like +855 23 xxx xxx.
Inside Cambodia you must put a 0 before the area code when calling from a different area.
The national plan lists 001, 007 and 008 as international access codes for different gateways, rather than only 00.
