Postal Telegraph and Telephone

A postal, telegraph, and telephone (or PTT) is or was a government agency responsible for postal mail, telegraph, and telephone services in many countries worldwide other than North America and Japan. In some countries, the former government-monopoly PTT has been partially or completely privatized in recent years. In some of those privitizations, the PTT was renamed completely, whereas in others, the name of the privatized corporation has been only slightly modified, such as PT Telecom in Indonesia.
