+66 country code: Thailand

Who uses +66

The +66 country code belongs to Thailand, the only country on this page. The country's official name is the Kingdom of Thailand, its ISO code is TH and its people are called Thai. The capital is Bangkok. Thai is the language of the country, and the currency is the Thai baht.

Thailand sits in Asia, within the South-Eastern Asia subregion. Calls to +66 numbers reach people and businesses across the country, including those in the capital, Bangkok.

Local time and number format

Thailand uses one time zone, Asia/Bangkok, at UTC+07:00. A Thai mobile number written in international format looks like this: +66 81 234 5678. The +66 replaces the leading zero of the national number, and the example shows the pattern used for mobiles in Thailand.

Calling and messaging over the internet

A +66 number can be called or messaged over the internet using a data connection. The call or message travels over that connection rather than the standard mobile voice service, and the cost depends on the service you use. This suits people contacting family, friends or colleagues in Thailand, and Thai residents reaching numbers in the country.

Slashtel sends prepaid mobile top-ups to these Thailand operators: AIS, TrueMove and dtac. You can top up a Thailand number through the recharge page, which covers the three operators listed. A top-up adds prepaid credit to a Thai mobile account.

Before you call, check the number against the international example format: +66 81 234 5678. The country code comes first, followed by the mobile number without its leading zero. Messaging works the same way, with the message sent to the +66 number over your data connection.

Thailand keeps Asia/Bangkok time at UTC+07:00 throughout the year, so the local clock on a call to Bangkok follows that single zone. The currency for any top-up is the Thai baht, and the operators receiving top-ups are AIS, TrueMove and dtac.
