Phone number details
How to read a Cambodia phone number
A Cambodia number is +855 followed by 8 digits. Knowing which of those digits mark a mobile is what tells you what the call will cost before you place it.
Inside Cambodia, numbers are dialled with a leading 0. Drop it when calling from abroad — keeping it is the single most common reason an international call fails.
Mobile prefixes
Landline prefixes
Prefix ranges still identify a line as mobile or fixed even where a number has been ported between operators, because the mobile and fixed blocks are separate and numbers do not move between them. Operator identification from a prefix, by contrast, stopped being reliable once portability arrived.

Rates vary by more than a factor of ten inside a single region, because each one is set by what the operator at the far end charges to accept the call. Taiwan is currently the cheapest place we publish a rate for near Cambodia.

All toolsFrequently asked questions
What is the country code for Cambodia?
The country code for Cambodia is +855. Dial this after the exit code (or use + on a mobile).
What does a Cambodia phone number look like?
A Cambodia number is written as +855 23 123 456: the country code +855 followed by 8 digits. That total is fixed by the national numbering plan, so a number with one digit missing is a typo rather than a shorter valid number.
How can I tell if a Cambodia number is a mobile?
By its leading digits. In Cambodia, a national number of 8 digits beginning with 1, 8, 9 is a mobile. That still works after a number has been ported between operators, because mobile and fixed-line blocks are separate ranges and numbers do not move between them.
Do I need to drop the leading 0 when calling Cambodia?
Yes. Cambodia uses 0 as a trunk prefix for domestic calls. When dialing internationally, drop the leading 0 from the local number.
How much does it cost to call Cambodia?
Telvio charges $0.28/min to Cambodia landlines and $0.28/min to mobiles. Billing is per second with no connection fees, so you pay only for the seconds you talk.
