How to Call Thailand from the USA?

When dialing Thailand from the USA, consider the international dialing format for Thailand, which includes the US exit code, Thailand country code, area code/mobile prefix, and local number.

Exit codes, also known as international access codes or international direct dialing (IDD) codes, route your calls to other countries. To make an international call from the US, dial the US exit code, i.e, 011. Or, you can use the (+) plus sign instead.

To contact Thailand from the US, dial the Thailand country code +66 right after the exit code. This connects your call to the Thai network so that your call reaches the correct recipient.

An area code is a part of the phone number format that tells the phone network which city or region to route your call before it reaches the local number. When calling Thailand from overseas, use the 2 or 3-digit area code without the leading 0. For example, dial 2 instead of 02 to reach Bangkok.

Here are some popular Thailand area codes:

A mobile prefix identifies the mobile network provider in Thailand. It usually starts with 06, 08, or 09. Like area codes, you must also drop the first ‘0’ of the mobile prefix when calling Thailand from abroad.
