What to check before using the 855 country code

Country codes are only one part of an international phone number. Exit codes, area codes, mobile prefixes, and local numbering rules can change how the final number should be dialed.

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.

Cambodia country code +855

Cambodia code, Cambodia country code, Cambodia phone code, Cambodia dialing code, Cambodia telephone code, 855 country code, and 00855 country code searches usually refer to the +855 international calling code.

Cambodia area codes

Cambodia area codes are normally written domestically with a leading 0. In international format, remove that 0 after +855, so Phnom Penh 023 is written as +855 23 followed by the local number.
