If you are calling from other country than Thailand to the Bangkok area, dial IDD of your country, then international phone number (country code) +66, after that phone area code of Bangkok 2 and call number. +66 - 2 (Telephone number).
Thailand Phone Codes. When calling Thailand add your international code! It will start with 0. Calling inside Thailand: omit the 66- and add a 0 to the city code. E.G. Bangkok is 02, Chiang Mai is 053. Bangkok is the only city with 7 digit no's.
