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

With thriving industries such as technology, tourism, agriculture, and finance, Thailand is a hub of economic activity offering extensive international collaboration opportunities. Additionally, its rich cultural heritage, vibrant festivals, and exquisite cuisine make Thailand a unique and desirable place to connect with on a personal level.

Understanding the nuances of interacting with this dynamic Southeast Asian nation is crucial for nurturing both business and personal relationships.

Guide to calling Thailand

Before dialing, ensure you're aware of the rates charged by your carrier for international calls to Thailand. You should also make sure your connection is reliable to avoid any issues caused by latency or choppy voice transmission.

1. Check the time in Thailand

Considering the time difference is important when calling Thailand. Thailand operates on Indochina Time (ICT), which is UTC+7. This means it’s typically 11–14 hours ahead of U.S. time zones, depending on your specific location in the U.S. and daylight saving time adjustments. Always check the local time in Thailand to ensure your call is made at a convenient hour.

2. Dial the exit code

For international calls from the U.S., the exit code is 011, indicating you're making an international call.

3. Enter Thailand's country code

Next, dial Thailand's country code (+66) to connect your call to Thailand.

4. Dial the area code and local number

Start with 011, followed by 66, the country code for Thailand.

For a landline

Input the area code for the specific region in Thailand you're calling, which can be one to two digits, followed by the seven-digit local number. For example, to call a landline in Bangkok with the area code 2 and the local number 1234567, you would dial 011-66-2-1234567.

For a mobile phone

Dial the mobile number directly after the country code, starting with an 8 or 9, followed by the rest of the number, making it a nine-digit sequence. For instance, to call a Thai mobile number like 0812345678, the correct sequence would be 011-66-812345678.

Tips for a successful call

Before calling Thailand, ensure you have a strong, stable internet connection to avoid interruptions. Have a contingency plan in place in case the call drops, such as agreeing beforehand on who will reconnect.

Understanding and respecting Thai business culture and etiquette is crucial. Formality is highly valued, so begin with a respectful greeting like "Sawadee ka" (if you are a woman) or "Sawadee krub" (if you are a man). Use professional titles such as "Khun" (Mr./Ms.) followed by the person’s first name. Always address senior individuals first and be aware that Thais may not express disagreement directly, so read between the lines.

Note local holidays, especially Songkran (Thai New Year in April) and Loy Krathong (festival in November), as these can affect business operations. Schedule calls around these periods to ensure availability.

While English is commonly spoken in business, showing respect by attempting basic Thai greetings or phrases can build rapport. Addressing individuals with their appropriate titles, such as "Doctor" or "Professor," shows respect and understanding of local customs.

Finally, be patient and flexible. Decision-making in Thailand may take longer than in the U.S., so allow time for discussions and avoid pressing for quick decisions.

Considerations for calling Thailand

When making calls to Thailand, it's essential to consider several factors beyond simply dialing the correct number. Understanding the nuances of language, culture, and time zones can significantly enhance your communication experience. Here's a comprehensive guide to help you navigate these elements:

Language and culture

While Thai is the official language of Thailand, English proficiency varies across the country. In major cities and tourist areas, you'll find many people who speak English, but it's always respectful and helpful to learn a few basic Thai phrases.

Common Thai greetings include:

  • Sawasdee—A universal greeting meaning "Hello," used at any time of day. It's followed by khrap (for men) or kha (for women) to add politeness.
  • Sawasdee khrap/kha—A polite way to say "Good morning/afternoon/evening."

Beyond greetings, a few polite phrases can go a long way in building rapport:

  • Khop khun khrap/kha— "Thank you."
  • Mai pen rai khrap/kha— "You're welcome" or "No problem."

Thai culture places a high value on respect and politeness. When addressing someone older or in a position of authority, use the honorific title khun before their name. For example, you would address someone named "Somchai" as Khun Somchai.

Time zones

Thailand observes Indochina Time (ICT), which is UTC+7. This means Thailand is significantly ahead of U.S. time zones. Here's a table illustrating the time difference:

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

For example, if it's 10:00 AM ET in New York, it's 10:00 PM ICT in Bangkok.

How much does it cost to call Thailand?

Call costs to Thailand can vary depending on your service provider, call duration, and time of day. To determine the most cost-effective option, check with your carrier for detailed rates.

Carrier rates are a primary factor influencing call costs. Different providers offer varying tariffs for international calls, which may be based on your plan type, such as pay-as-you-go or a dedicated international calling plan. Some carriers may provide discounted rates for calls to Thailand during off-peak hours or as part of a package deal that includes a set number of international minutes.

Call duration also significantly affects the overall cost. Longer calls naturally result in higher charges, especially with pay-per-minute plans. Managing the length of your conversations can contribute to cost-effective communication.

The time of day you make the call can also impact costs due to peak and off-peak rate variations. Calls during peak hours are generally more expensive than those made during off-peak periods, such as late evenings or weekends, depending on your carrier's specific rate schedule.

By considering these factors and planning your calls accordingly, you can manage your communication expenses effectively while staying connected with contacts in Thailand.
