Cambodia
Cambodia’s country codes are essential for international communication and digital operations. Its ISO 3166 codes are KH (two-letter) and KHM (three-letter), used in global databases and shipping. The international calling code is +855, required when dialing Cambodian phone numbers from abroad. The country-code top-level domain (ccTLD) is .kh, reserved for entities registering websites within Cambodia. The official currency, the Cambodian riel (KHR), is used in local transactions and financial reporting, though U.S. dollars are widely accepted. Together, these identifiers support routing calls, verifying jurisdictions, registering domains, and conducting business within Cambodia’s expanding digital economy.

How to call Cambodia
From outside Cambodia, dial your international access prefix, then +855, then the national number. Drop the leading trunk zero when the destination numbering plan requires it.
