Why Expand Your Business to Cambodia?
Cambodia's GDP reached approximately $46 billion in 2024, with growth projected to hit 6% in 2025 driven by rebounding tourism, garment and footwear exports, and a fast-expanding manufacturing base. The country has sustained average annual growth of around 6-8% for over two decades, attracting FDI from China, South Korea, Japan, Singapore, and the US. Key sectors include textiles and apparel, tourism, construction, real estate, agriculture, and a rapidly growing digital economy centered in Phnom Penh.
Foreign businesses entering Cambodia often face a fundamental challenge: Cambodian consumers and local B2B contacts heavily prefer dealing with locally reachable companies. A call from an unrecognized international number is frequently ignored. A Cambodia virtual phone number with a recognizable Phnom Penh (023) or Siem Reap (063) area code signals that your business is accessible and committed to the local market - boosting answer rates and accelerating trust. You get all the benefits of local presence without leasing office space or hiring on the ground.
Inbound Customer Support

Sales & Outbound Prospecting
Calling a Phnom Penh prospect from a +855 023 local number dramatically increases the likelihood they will pick up. Use FoneSwift's AI voice agents and power dialing to run high-volume outbound campaigns with local caller ID.
Tourism & Booking Confirmations
Travel operators and hospitality businesses can use Siem Reap or Phnom Penh local numbers to send booking confirmations, pre-arrival instructions, and upsell offers via SMS - channels Cambodian travelers actively use.

Businesses Using Cambodia Phone Numbers
Cambodia's economy spans tourism, manufacturing, real estate, and a fast-moving digital sector. Across every vertical, a local +855 number is the fastest way to signal credibility and get your calls answered.
Tourism & Hospitality
Tourism is Cambodia's second-largest industry. Hotels, tour operators, travel agencies, and OTAs use local Siem Reap (063) and Phnom Penh (023) numbers so that arriving and prospective travelers can reach them at local rates without international calling friction.
Garment & Apparel Manufacturing
Cambodia is one of the world's top garment exporters. International buyers and sourcing agents use local Phnom Penh numbers to coordinate with factories, quality control teams, and logistics providers on the ground - removing the perception of being a remote overseas client.
Real Estate & Construction
Cambodia's property boom, especially in Phnom Penh and Sihanoukville, has attracted significant foreign investment. Real estate agencies, property developers, and PropTech platforms use local numbers to handle inbound leads from both domestic buyers and the overseas Cambodian diaspora.
Fintech & Microfinance
Cambodia has one of Southeast Asia's most dynamic mobile money ecosystems (dominated by Wing, ABA Pay, and Pi Pay). Fintech companies, MFIs, and neobanks use local virtual numbers for customer onboarding calls, loan disbursement notifications, and two-factor authentication via SMS.
NGOs & International Development
Cambodia hosts hundreds of international NGOs and UN agencies. These organizations use local virtual numbers to maintain accessible field offices, coordinate with government ministries, and run community helplines without paying for dedicated landline infrastructure in every province.
E-Commerce & Digital Retail
Cambodia's internet penetration is growing fast, with mobile-first commerce expanding beyond Phnom Penh. E-commerce platforms and D2C brands use local numbers for order confirmation calls, customer service, and SMS delivery notifications that customers actually open.
Legal, Accounting & Professional Services
Foreign law firms, accounting practices, and corporate advisory firms serving the Cambodian market use local Phnom Penh numbers for client intake and confidential consultations, matching the expectations of locally registered counterparts.
About Cambodia Phone Numbers
Cambodia's telecommunications market is regulated by the Telecommunication Regulator of Cambodia (TRC), an independent body overseeing fixed-line, mobile, internet, and broadcast services. The country uses country code +855, with a numbering plan that assigns 2-digit geographic area codes to provinces (e.g., 23 for Phnom Penh, 63 for Siem Reap, 34 for Sihanoukville) for landlines, and operator-specific prefixes for mobile numbers. The mobile market is dominated by Cellcard, Smart Axiata, and Metfone, with several smaller operators including qb, CooTel, and Seatel. Cambodia operates in a single timezone - Indochina Time (ICT), UTC+7 - with no Daylight Saving Time, which simplifies scheduling for international teams.
FoneSwift gives you instant access to Cambodian local geographic numbers, national numbers, toll-free 1800 numbers, and mobile virtual numbers - all manageable from one dashboard. Activate a Phnom Penh (023) number in minutes, configure IVR menus, set up call forwarding to your global team, and enable two-way SMS with no hardware required. Whether you're a startup testing the Cambodian market or an enterprise scaling customer support across ASEAN, FoneSwift provides the infrastructure to sound local and operate globally.
Businesses using Cambodian numbers for outbound calling and SMS must comply with TRC regulations, which mandate that organizations maintain internal Do Not Call lists and promptly honor opt-out requests. Cambodia has not yet enacted a comprehensive data protection law, but best practice - and an expectation of international enterprise partners - requires treating all phone numbers and contact data as personally identifiable information with appropriate encryption and access controls. FoneSwift's platform is built to support compliant call and messaging workflows, giving your team guardrails without slowing down operations.

Interesting Facts about Cambodia
Discover what makes Cambodia unique and why local phone numbers matter for your business.
Cambodia Has No Daylight Saving Time - Ever
Cambodia runs on Indochina Time (ICT, UTC+7) year-round with no clock changes. For businesses managing international call schedules, this is a genuine operational advantage - Cambodia's offset from global partners never shifts.
Mobile Penetration Outpaced Fixed Lines Decades Ago
Fixed-line infrastructure in Cambodia was severely damaged during decades of conflict and was never fully rebuilt. Mobile networks filled the gap, and today the vast majority of Cambodians communicate primarily via mobile. This makes mobile virtual numbers especially powerful for reaching customers.
Three Competing International Gateways
When calling internationally from within Cambodia, callers can choose between three operator gateways: 001 (MPTC/Telecom Cambodia), 007 (Royal Telecam International), and 008, each offering different rates. This multi-gateway system is unique in the region and reflects Cambodia's open telecom market.
Smart Axiata Helped Digitize Rural Cambodia
Smart Axiata's 4G rollout extended mobile coverage deep into Cambodia's rural provinces, enabling digital payments, e-commerce, and VoIP services in areas where landlines never existed. Over 50% of Cambodians now own at least one smartphone.
Wing Money Pioneered Mobile Banking Before Most of Southeast Asia
Cambodia's Wing mobile money service launched in 2009 and quickly became one of the first mobile payment platforms in Southeast Asia to reach significant rural adoption. This mobile-money-first culture makes SMS and voice-based financial communications especially effective with Cambodian audiences.
The TRC Publishes Official Mobile Prefix Allocations
Unlike many countries where carrier prefix data is scattered or unofficial, Cambodia's Telecommunication Regulator of Cambodia (TRC) publicly publishes an up-to-date list of mobile prefix allocations at trc.gov.kh. This transparency makes it straightforward to identify carriers and route calls efficiently.
Virtual Number Types in Cambodia
Every business has unique needs. Choose the perfect telephony footprint in Cambodia to maximize local trust, nationwide reach, or high-volume SMS.
Local Numbers
Geographic numbers tied to specific Cambodian provinces and cities. Each area code corresponds to a region - for example, 023 for Phnom Penh and 063 for Siem Reap.
Best for businesses targeting customers in a specific city or province, where local caller ID increases trust and answer rates.
Toll-Free Numbers
Cambodian 1800 numbers that are free for callers dialing from within the country. Ideal for inbound customer service lines.
Best for national customer service desks, helplines, and support operations where you want to remove barriers for callers across all provinces.
National Numbers
Numbers beginning with the 078 prefix that are reachable from anywhere in Cambodia, without being tied to a specific geographic region.
Best for businesses that want a single recognizable number accessible country-wide without committing to a specific city identity.
Mobile Numbers
Virtual numbers using Cambodian mobile operator prefixes (Cellcard, Smart, Metfone), capable of receiving calls and SMS.
Best for SMS-first workflows, OTP delivery, appointment reminders, and campaigns targeting mobile-centric Cambodian consumers.
