Telephone numbers in Taiwan
Area code
Source:The emergency numbers in Taiwan are 110 and 119.
When making an inter-area long-distance call from within Taiwan, a long-distance prefix "0" is required. If calls are made from within the same area code, then the area code does not need to be included. Inter-area calls are defined as long-distance phone calls even when the two numbers have the same prefix.
If calls are made from outside Taiwan, the "0" of the area code prefix is omitted.

International dialling
International dialling from Taiwan follows the following pattern:Carrier selection code – Country calling code – Area code – Subscriber number
Carrier selection codes, which direct the call via one of several providers, are as follows:
- 002 – Chunghwa Telecom
- 005 – Asia Pacific Telecom
- 006 – Taiwan Mobile
- 007 – Far EasTone
- 009 – Chunghwa Telecom
Country calling code
International dialling codes were assigned by the International Telecommunication Union, an agency of the United Nations, to its member states and their dependencies in the 1960s. Despite the Republic of China on Taiwan still holding the Chinese seat in the UN, and hence the ITU, other member states declared that "the only representatives of the people of China are the delegates to the ITU and its permanent organs appointed by the Central Government of the People's Republic of China". This led to the People's Republic of China being assigned the country code 86. Consequently, in the early 1970s, Taiwan had to be unofficially assigned a separate code, 886, although there was pressure from China to change this to 866. This had to be listed as "reserved", but in 2006, the code was formally allocated to "Taiwan, China".
