The Cambodia country code is +855 — reaching Southeast Asia's fast-growing Kingdom, ~17 million Cambodians + ~20 million mobile subscriptions across Cellcard, Smart Axiata + Metfone. Home of Angkor Wat + a de-facto dual USD/Riel economy — Cambodian bank verifications (ABA, ACLEDA, Wing) all expect +855.
Cambodia was assigned +855 by the ITU — placing it in zone 8 with East + Southeast Asia. The capital Phnom Penh uses area code 023, and the country runs a unique dual USD/Riel economy.
Cambodia uses the +855 country code, placing it in ITU zone 8 alongside Thailand +66, Vietnam +84, Laos +856, Malaysia +60 + Singapore +65. The three-digit +855 sits in the Southeast Asian numbering bloc, neighboured by Thailand to the west + Vietnam to the east.
Cambodia's telecom industry is regulated by the TRC (Telecommunication Regulator of Cambodia). Three main mobile carriers dominate: Cellcard (CamGSM), Smart Axiata + Metfone (Viettel-owned, the largest by subscribers). Mobile penetration exceeds 100% — many Cambodians carry multiple SIMs. 4G/LTE is widespread + 5G is rolling out.
Cambodian area codes carry a leading <b>0</b> domestically (dropped internationally). Major: <b>023</b> Phnom Penh, <b>063</b> Siem Reap, <b>053</b> Battambang, <b>034</b> Sihanoukville, <b>042</b> Kampong Cham. Mobiles use many prefixes (010–017, 060–099) — written as +855 followed by the subscriber number.
Cambodia runs on two currencies at once. The official currency is the Cambodian Riel (KHR, ៛), but the US dollar circulates so widely that ATMs dispense USD + most larger transactions — hotels, electronics, rent — are priced in dollars. Riel is mainly used for small change + everyday purchases. This de-facto dual USD/Riel system makes Cambodia unusually convenient for international business + travellers.
A Cambodian phone number in international format is written as +855 [area code without 0] [local]. Example: +855 23 123 456 for Phnom Penh (023 123 456 domestic), +855 63 123 456 for Siem Reap, +855 12 345 678 for a Cellcard mobile.
Cambodian mobile numbers use a wide range of prefixes (010–017, 060–099 domestically; +855 1X / +855 6X-9X internationally). Drop the leading 0 internationally. Cambodian numbers are variable length — Phnom Penh 023-numbers are typically 6 digits + mobiles are 6-8 digits.
From the Royal Palace in Phnom Penh to the temples of Angkor near Siem Reap, every Cambodian number lives behind a +855. Pick the area code that matches your customer city.
Every country uses a different exit code before +855. From any mobile, + replaces the exit code — so +855 23 123 456 works worldwide. Always drop the leading 0 from Cambodian numbers.
