Area Code 89 – Taitung

Overview of Taiwan Area Code 89

Area code 89 is the National Destination Code (NDC) assigned to the Taitung region in Taiwan. It is a geographic code used for fixed-line (PSTN) services within Taitung County, which is located on the southeastern coast of the island. The region is known for its mountainous terrain, indigenous communities, and scenic coastal areas.

Geographic Coverage

The code covers the entire Taitung County, including the administrative capital Taitung City (台東市) and surrounding townships such as Chenggong (成功), Guanshan (關山), and Beinan (卑南). It also serves smaller coastal and inland communities. The area is sparsely populated compared to western Taiwan, and the fixed-line network density is lower.

Dialing Formats

When dialing a Taitung fixed-line number, the subscriber number length is typically 7 digits after the area code. The complete national (trunk) format is:

• National dialing (from within Taiwan): 0 89 XXX XXXX (the leading 0 is the trunk prefix)
• International dialing (from outside Taiwan): +886 89 XXX XXXX (omit the leading 0)

For example, a local number in Taitung City might be 089 123 4567 when dialed domestically, or +886 89 123 4567 from abroad.

Caller Instructions

• Local callers within Taitung: If you are calling from another fixed-line in the same area code, you may dial only the 7-digit subscriber number (without the area code) in many cases. However, for clarity and to avoid issues, it is recommended to dial the full national format 089 XXX XXXX.
• Callers from other regions in Taiwan: Dial 0 89 XXX XXXX.
• International callers: Dial the international access code (e.g., 011 from the US), then Taiwan’s country code 886, then the area code without the leading zero: 89, followed by the 7-digit subscriber number.

Overlay and Numbering Considerations

As of the latest ITU-T E.164 national numbering plan, there is no overlay code for Taitung; the 89 code remains exclusive to this geographic area. Number portability is available for fixed-line services, meaning that if a subscriber moves to a different operator, they may retain their number, but the geographic significance remains tied to the original location.

Usage Notes

This code is used exclusively for fixed-line services. Mobile numbers in Taiwan use separate non-geographic prefixes (e.g., 090-099). VoIP services may use geographic codes, but they are not tied to a physical location. When dialing from abroad, always check the current dialing procedures, as some carriers may require different access codes.
