Most phone numbers in Thailand are written in the following formats:

   Prefix: long distance or international
   --------------------------------------
   |   Carrier or area code 
   |   --------------------
   |   |   Subscriber number
   |   |   -----------------
   v   v   v
   0   A   SSS-SSSS     - Local format
  +66  A   SSS-SSSS     - International format

Most telephone numbers in Thailand have 8 digits and are written in the format of "A SSS-SSSS". Here are some examples: 2 356-1111; 2 134-7795;.

When dialing locally inside Thailand, the long distance prefix of "0" is required. So the format becomes "0 A SSS-SSSS".

When dialing from outside of Thailand, the international dial-in prefix "+66" is required. So the format becomes "+66 A SSS-SSSS".

When dialing from Thailand to other countries, the international dail-out prefix "+" or "00" required.
