How to Call a US Number from Thailand?

Before dialing a US number from Thailand, you must understand the correct sequence of codes and the US phone number format. This includes the exit code of Thailand, the US country code, the area code, and the local/mobile number. You should also consider the time difference to ensure your call connects at the right time.

• Thailand’s exit code is “001”.
• The US country code is “1”.

To dial the US from Thailand, enter the exit code of Thailand (001), followed by the US country code (1), the 3-digit area code, and the receiver's phone number.

To dial a US landline number from Thailand, first dial Thailand’s exit code (001), the American country code, the area code, and the receiver’s landline number.

1. Dial Thailand’s exit code (001, 009, or 00 depending on your provider).
2. Enter the US country code (1).
3. Dial the area code of the US city you want to reach (usually three digits).
4. Enter the local landline number (7 digits).

For example, if you are calling someone in Albany from Thailand, the number format will be: 001-1-518-XXX-XXXX, where 518 is the area code of Albany and the remaining numbers are the receiver's landline number.

If you’re calling a US mobile number from Thailand, enter Thailand’s exit code, followed by the US country code, area code, and the recipient's phone number.

1. Dial Thailand’s exit code (001).
2. Enter the US country code (1).
3. Enter the area code of the destination city.
4. Dial the mobile number of the receiver.

For example, if you are calling someone in Syracuse from Thailand, the number format will be: 001-1-315-XXX-XXXX, where 315 is the area code of Syracuse and the remaining is the receiver’s mobile number.

Before making an international call, it’s essential to consider the time difference between Thailand and the United States. The US spans six primary time zones, while Thailand follows only one time zone, i.e., Indochina Time (ICT), which is UTC+7.

The best time to call the US from Thailand is during US business hours, typically between 8:00 AM and 6:00 PM in the specific US time zone you are calling. Since there’s a 12 to 17-hour time difference between the United States and Thailand, it’s important to plan your calls carefully.

In Thailand, this usually means placing your call late at night or early in the morning, depending on the US region:

• For the Eastern Time Zone (EST), call between 8:00 PM and 6:00 AM Thailand time.
• For the Pacific Time Zone (PST), call between 11:00 PM and 9:00 AM Thailand time.

Always check the exact local time in the US city you’re contacting to avoid calling too early or too late. This will help you reach your contact at a convenient hour and improve your chances of a successful call.

There are several ways to make calls from Thailand to the US besides the traditional landline and mobile services. This includes cloud telephony services and social media apps.

A modern and cost-effective option is using a cloud phone system like Calilio. Such a service allows you to make calls over the internet (VoIP) without traditional phone lines. You can get virtual US numbers, manage calls through a business phone system, and access advanced call features from any device. This is ideal for businesses handling frequent international calls.

You can also call US contacts using social media and messaging apps like WhatsApp, Skype, Viber, or Messenger. These platforms use internet data for voice and video calls. Both you and the recipient must have the same app installed and a stable internet connection. This method is free or low-cost but depends on internet quality for clear and stable calls.

The cost of calling the USA from Thailand depends on your method. International call rates can vary by service provider, call type, and connection quality. If you call through a regular landline or mobile network, charges can range from 10 to 50 THB (Thai Baht) per minute or more, depending on your plan. Some mobile carriers offer special international calling packages to reduce these rates.

If you use social media apps like WhatsApp, Skype, or Viber, calls are typically free since they rely on an internet connection instead of traditional phone networks. However, both the caller and the receiver must use the same app for the call to work.

Cloud telephony services like Calilio provide a more affordable option. These services charge a fixed monthly fee or low per-minute rates for international calls, often much cheaper than traditional phone lines. They also offer virtual US numbers with advanced call management tools for businesses at a reasonable price.

Making an international call from Thailand to the United States is simple if you follow the correct dialing format and choose the right method. Whether you’re calling a US landline or mobile number, the key is to dial the proper country and area codes to connect without any issue. Also, consider the time difference to place your call at a suitable hour.
 

To call a phone number in Thailand from the US, dial the international exit code 011, followed by Thailand’s country code 66, then the area code (without the leading zero), and finally the local phone number.

The most affordable ways to call the US from Thailand include using cloud telephony services like Calilio, which offer low per-minute rates and virtual US numbers.

The exit code of Thailand is “001”.
