Cambodia number screening
Cambodia has far more SIMs than people, so a valid number is not a distinct person — and Telegram, not WhatsApp, is where business happens.
Mobile number format
Cambodian mobile numbers are 9 to 10 digits nationally with a leading 0 — 8 to 9 after stripping it for +855 — spread across the 01x, 06x, 07x, 08x and 09x ranges. A 2013 renumbering added digits, so shorter legacy numbers in old files are no longer valid.
Main carriers
- Smart Axiata
- Cellcard
- Metfone
Smart Axiata, Cellcard and Metfone — the last owned by Vietnam's Viettel — split the market. SIM subscriptions have long exceeded the population because on-net calling is cheap and people carry cards from several networks, so one person routinely shows up as several records. Deduplication matters more than volume here.
On the ground
The US dollar circulates alongside the riel and urban pricing is largely in dollars, so quoting in USD creates no friction. Mobile payments run through local bank apps and the Bakong network, with accounts commonly tied to a mobile number, which keeps numbers relatively stable. Phnom Penh also hosts a substantial Chinese-speaking business community, so Chinese-language outreach lands.
Screening guidance
Normalise against the 9-to-10 digit range, then check validity and carrier. Put Telegram registration first — it is the primary reachable channel in Cambodia — with Facebook as the supplement, and treat low WhatsApp hit rates as normal rather than as a data problem. Finish by deduplicating toward people, or the multi-SIM habit will inflate your count badly.
Key platforms in Cambodia
Cambodia is the rare Southeast Asian market where Telegram leads: shops take orders on it, agents and logistics coordinate on it, and groups and channels function as everyday work tools. Facebook handles discovery and shopfronts, while WhatsApp is noticeably thinner than in neighbouring countries.
FAQ
How many digits is a Cambodian mobile number?
Nine to ten digits nationally with a leading 0, typically in the 01x, 06x, 07x, 08x and 09x ranges. Strip the 0, add +855 and you get 8 to 9 digits. Cambodia added digits in a 2013 renumbering, so shorter legacy entries are dead and old files deserve a full re-validation pass.
Do Cambodians use WhatsApp or Telegram?
Mostly Telegram. Cambodia is one of the few Southeast Asian markets where it dominates — merchants take orders, agents negotiate and logistics get coordinated in Telegram groups, while Facebook serves as the shopfront. WhatsApp is thinner than in neighbouring countries, so a low hit rate is not a sign of bad data.
Why does a Cambodian list shrink so much after deduplication?
Because multi-SIM ownership is the norm. SIM subscriptions have long outnumbered the population — on-net calls are cheap, so plenty of people carry Smart, Cellcard and Metfone lines at once. Counting by number therefore overstates the real headcount, and budgeting or reach estimates should be done only after deduplication.
