Thailand

Time Traveler
  In 1880, His Majesty King Chulachomklao assigned his brother Prince Bhanurangsiswangwong to establish the first postal service to keep abreast of the rapid progress of neighboring nations' communications. He took position as the first Director-General of the Post and Telegraph Department. Like most other postal services, to improve the management of the respective departments, the postal service and the telegraph service were split up into independent departments.

Cool Facts!
  The Thai postal system is very typical of a local Asian postal system, with modernized postal services ranging from Express Mail, Money Order Services and Fine payments. One interesting cost-saving scheme I noted for customers would be the "Economy Air" service. Instead of flying the mail directly to its destination by air, the mail is flown by air for half of its journey and transported overland to its final destination.

  The Thai postal code system is roughly as follows: A Thai postal code has 5 digits. The first two digits correspond to the city's code and the last three digits correspond to the district's 3 digit code. The northern city of Chiang Rai has the 2-digit code 57 and one of its districts Mae Chan has a triple-code of 110 so the overall code is 57110.
