About Thailand Calling Code
To reach Thailand from another country, first dial the international calling code +66 โ assigned by the ITU โ followed by the local number. Thailand is located in Asia, in South-Eastern Asia.
Thailand is known locally as เธเธฃเธฐเนเธเธจเนเธเธข โ Bangkok is the capital. When saving an international contact, write the number in full international format with +66 so it works from any country.
International calling codes follow the ITU-T standards E.123 and E.164, which define how phone numbers are written and dialed across borders. The prefix you dial after the exit code tells the global telephone network which national network to route the call to.
Where the +66 Calling Code Is Used
The country code +66 is assigned to Thailand, located in South-Eastern Asia, with the capital Bangkok. This code is part of the international telephony numbering plan and is used for all calls made to Thailand from outside the country.
When a number is written as +66 โฆ, the +66 prefix directs your call to the Thailand national network. After the prefix, dial the area code without its leading zero, then the subscriber number โ the same pattern for landlines and mobiles.
ITU-T E.164 groups calling codes by world region; codes beginning with 6 cover the part of the world that includes Thailand, in South-Eastern Asia. Storing numbers with +66 and omitting the domestic leading zero keeps contacts dialable from anywhere.
Thailand Phone Number Formats
The ITU E.164 format for Thailand numbers is +66 + area code + subscriber number, used for landlines and mobiles alike. Here is the general structure:
๐ฑ Number Structure
- International format: +66 [area code] [subscriber number]
- From abroad: exit code + +66 + local number (drop the trunk prefix 0)
- Within Thailand: dial the local number directly
Numbering plans vary: closed plans use fixed-length national numbers, while open plans allow variable lengths with a trunk prefix (usually 0) that is dropped for international calls. For calls to Thailand, replace the trunk zero with +66.
Time Zone in Thailand
The local time in Thailand follows the Asia/Bangkok time zone (UTC+07:00 UTC). Check the time difference before you dial so your call arrives during waking hours.
Time differences matter when calling Thailand: if it is UTC+07:00 there, a morning call from Europe may reach Bangkok in the afternoon, while callers in the Americas should check the offset to avoid late-night calls.
If Thailand observes daylight saving time, its UTC offset shifts by an hour twice a year. Double-check the current offset before time-sensitive calls, especially in spring and autumn.

Example: Calling Thailand Numbers in Practice
Here is how a typical call to Thailand works, depending on where you are calling from:
๐ From the United States or Canada
- Dial the US/Canada exit code 011
- Dial the Thailand country code +66
- Dial the local number (area code + subscriber number, without the trunk prefix 0)
Example: 011 +66 [area code] [number]
๐ From the United Kingdom or Europe
- Dial the international access code 00 (or use the + symbol on mobile)
- Dial the Thailand country code +66
- Dial the local number
Example: 00 +66 [area code] [number], or +66 [area code] [number] from any mobile phone
If the local number begins with a trunk prefix (commonly 0), remove it when dialing internationally โ +66 takes its place. The remaining digits are dialed exactly as written.
