Connecting with Cambodia from the United States is essential for various reasons, from business to personal.

Sectors such as technology, tourism, agriculture, and finance are thriving in Cambodia, making it a significant player in international business. Additionally, Cambodia's rich cultural history, highlighted by its ancient temples, vibrant festivals, and unique cuisine, offers compelling reasons to establish strong communication links.

Understanding the nuances of interacting with Cambodia is crucial for nurturing relationships and ensuring successful, meaningful connections.

Guide to calling Cambodia

Making international calls to Cambodia requires a few simple steps. Check the rates with your provider, secure a good connection, and be mindful of the time difference to avoid calling at inconvenient hours.

1. Check the time in Cambodia

First, consider the time difference when making international calls to Cambodia. Cambodia operates on Indochina Time (ICT), which is UTC+7.

This means Cambodia is generally 11–14 hours ahead of U.S. time zones, depending on your location and any daylight saving adjustments. Always verify the local time in Cambodia to ensure your call is convenient for the recipient.

2. Dial the exit code

For international calls from the U.S., start by dialing the exit code 011.

3. Enter Cambodia's country code

Next, dial Cambodia's country code, which is +855.

4. Dial the area code and local number

Start with 011, followed by 855, the country code for Cambodia.

For a landline

Dial the local area code, which is usually a single digit, followed by the local number, typically six digits. For example, to call a landline in Phnom Penh with the area code 23 and the local number 123456, you would dial 011-855-23-123456.

For a mobile phone

Dial the mobile number directly after the country code. Cambodian mobile numbers usually start with a two-digit prefix followed by seven digits. For instance, to call a mobile number like 012345678, the sequence would be 011-855-12-345678.

Tips for a successful call

Before placing a call to Cambodia, ensure you have a strong connection to avoid disruptions. Have a backup plan in case the call drops, such as knowing whether to call back immediately or wait for the other party to reconnect.

Understanding and respecting Cambodian business culture and etiquette is crucial.

Business culture in Cambodia values formalities and hierarchy. Begin with a respectful greeting, such as "Chum reap suor" (hello in Khmer). Address individuals using titles like “Lok” (Mr.) or “Lok Srey” (Mrs./Ms.) followed by their first name.

Be mindful of local holidays and festivals, such as Khmer New Year in April and the Water Festival in November, which can affect business operations. It’s wise to avoid scheduling calls during these times.

While English is commonly used in business, learning a few Khmer phrases can help build rapport. Simple greetings or expressions of thanks can go a long way.

Use professional titles when applicable. For example, addressing someone as “Doctor” or “Engineer” shows respect for their position.

Be patient and flexible, as the pace of business communication in Cambodia may differ from that in the U.S. Allow time for responses and decision-making, and be prepared for a more relaxed approach to scheduling and deadlines.

Considerations for calling Cambodia

When planning to connect with individuals in Cambodia, be mindful of the various factors that can influence your calls. These factors extend beyond mere logistical considerations, encompassing cultural nuances and communication etiquette that are crucial for successful interactions. Here's a breakdown of the key elements to consider:

Language and culture

The official language of Cambodia is Khmer, spoken by the majority of the population. While English is increasingly prevalent, especially in urban areas and within the business community, initiating conversations in Khmer demonstrates respect and fosters stronger connections.

Common Khmer greetings include:

  • ជំរាបសួរ (Chum reap suor): A versatile greeting meaning "Hello." Similar to "Kumusta" in Tagalog, it's suitable for various situations.
  • សួស្តី (Sous-dey): A more formal greeting, typically used in professional or respectful contexts.
  • តើអ្នកសុខសប្បាយជាទេ? (Teuk neak sok sabay chea te?): A polite way to ask "How are you?"

Beyond verbal greetings, you’ll want to adhere to Cambodian cultural norms. Cambodians highly value politeness and respect for elders. When addressing someone older, using the honorifics "Lok" (for men) or "Lok Yeay" (for women) before their name is customary.

Time zones

Cambodia observes Indochina Time (ICT), which is UTC+7. This translates to a significant time difference with the U.S., making it essential to schedule calls carefully.

U.S. time zonesCambodia
Eastern (ET)12 hours ahead
Central (CT)13 hours ahead
Mountain (MT)14 hours ahead
Pacific (PT)15 hours ahead

For instance, if it's 10:00 AM ET in New York, it's 10:00 PM in Phnom Penh.

How much does it cost to call Cambodia?

Calling Cambodia from the U.S. can incur varying costs depending on your service provider and calling plan.

Different carriers offer varying international call rates. Check with your provider for their specific rates to Cambodia. Some may offer discounted rates for international calls, especially during off-peak hours.

Explore international calling plans or bundles that include minutes to Cambodia. These can often provide more cost-effective rates compared to standard per-minute charges.

Longer calls naturally result in higher charges. Manage your call duration to control costs, especially if you're on a per-minute plan.

Peak and off-peak rates can apply, with calls during peak hours potentially costing more. Check your carrier's rate schedule for details.

You can also consider using Voice over Internet Protocol (VoIP) services, which often offer lower rates for international calls.
