The numbering plan is based on a closed numbering scheme, with each subscriber having a fixed number of digits. The number consists of area codes or operator codes corresponding to the province or the operator and the subscriber number corresponding to individual subscriber numbers.

The numbering plan is structured in the following manner:

Number known internationally: CC + NDC + SN
Number known nationwide: NDC + SN
Number known locally (within an area): SN

where:


CC: Country Code (855 for Cambodia)
NDC: National Destination Code or Area Code
SN: Subscriber Number

Fixed PSTN Area Codes



For fixed PSTN (Public Switched Telephone Network) including wire-line and www networks, the following Area Codes apply. When calling from a different NDC, subscribers need to dial “0” as the first digit before NDC.
