Thailand country code +66: dialling in and out
The +66 code, the dropped 0, and the codes inside a Thai SIM.
By the Local SIM Thailand team, checked October 2, 2026
The short answer
Thailand's country code is +66. From abroad, dial +66 and drop the first 0 of the number: a mobile written 08X XXX XXXX becomes +66 8X XXX XXXX. To call another country from Thailand, dial 001, or + on a mobile, then the country code. Thai mobiles have nine digits after +66.
- +66 is the country code; the 0 in front is the trunk prefix, dropped from abroad.
- Mobiles: ten digits at home and nine after +66; landlines have eight digits after +66.
- Calling out of Thailand: 001, or + on a mobile, then the country code.
- A Thai SIM identity starts 8966; its network identity starts with 520.
- Emergency: 191 police, 1669 ambulance, 199 fire, 1155 tourist police.

The codes your phone shows
MCC 520
Thailand's mobile country code. Every Thai network identity begins with 520, followed by a short code for the operator.
ICCID starting 8966
A SIM's serial number begins with 89, for telecommunications, then 66, the country code; Thai issuers sit in the 89 66 range.
Landlines
Eight digits after +66, and Bangkok with the provinces around it uses 2, so an office number reads +66 2 XXX XXXX from abroad.
