How to call Thailand: step by step

The full sequence is: exit code + 66 + local number (minus the leading 0).

  1. 1

    Dial your exit code

    From the United States and Canada that is 011. From most of Europe, Asia, and Africa it is 00. On any mobile you can simply press and hold 0 to get a + instead, which works from anywhere.
  2. 2

    Dial 66

    66 is the country calling code for Thailand. It never changes and it is the same from every country in the world.
  3. 3

    Drop the leading 0

    Numbers written for domestic use in Thailand start with a 0. That is a national trunk prefix, not part of the number; remove it when dialling from abroad. 2 123 4567 is what you dial after +66.
  4. 4

    Check the time first

    Thailand is on ICT (UTC+7, no DST). Business calls placed outside local working hours are the most common reason an international call goes unanswered.
