Exit code or plus format
On a mobile phone, the plus sign usually replaces exit codes such as 00 or 011. From a landline, use the international access code for the country you are calling from, then 855.
Country calling code, dial code, or prefix
People may call 855 the Cambodia country code, country calling code, phone code, dial code, or international prefix. In each case, use +855 before the rest of the Cambodia number.
Mobile phone or landline
After +855, the next digits may be an area code, mobile prefix, service prefix, or local number. Check whether you are calling a mobile phone or landline because rates can differ.
