Area Code 71 – Kaohsiung

Overview of Taiwan's +886 71 Geographic Code

The international dialing prefix +886 71 corresponds to a geographic numbering area within Taiwan's national telecommunications plan. Under the ITU-T E.164 standard, this code is classified as a National Destination Code (NDC) for fixed-line services. The 71 prefix is allocated to the administrative region of Kaohsiung, a major special municipality located in southern Taiwan. This area code is used for traditional PSTN (Public Switched Telephone Network) lines, as well as for VoIP and ISDN services that are geographically associated with the region.

Geographic Coverage and Administrative Jurisdiction

Kaohsiung is one of Taiwan's five special municipalities, and its numbering plan covers the entire city, including its 38 administrative districts. This includes the former Kaohsiung County, which was merged into the city in 2010. The 71 code serves both urban and rural areas, from the densely populated city center to the outlying districts. The code is used for fixed-line services, including residential, business, and government lines. It is important to note that while mobile numbers in Taiwan begin with 09 and are non-geographic, the 71 prefix is exclusively for fixed-line services.

Dialing Formats and Caller Instructions

For callers within Taiwan, the local dialing format is 07-XXXXXXX, where the leading 0 is the trunk prefix, and the 7 is the area code. The subscriber number is typically 7 or 8 digits long. For example, a local call to a number in Kaohsiung would be dialed as 07-1234567.

For international callers, the format is +886 7 XXXX XXX (or +886 71 XXXXXXX when including the full NDC). The leading 0 is dropped when dialing from abroad. For instance, to call a Kaohsiung number from the United States, you would dial 011 886 7 XXXX XXX (or 011 886 71 XXXXXXX).

Overlay and Numbering Considerations

Taiwan's numbering plan does not currently use overlay codes for geographic areas. Each region has a unique area code, and 71 is exclusively assigned to Kaohsiung. However, due to number exhaustion, some areas have introduced additional codes, but Kaohsiung's 71 code remains the primary fixed-line code. There are no plans for an overlay in the near future, so callers can rely on the 71 prefix for all fixed-line numbers in the region.

Practical Usage and Routing

When dialing from a mobile phone within Taiwan, the same format applies: 07-XXXXXXX. For international callers, it is essential to use the correct country code (+886) and to omit the leading 0. The call will be routed through Taiwan's PSTN to the appropriate local exchange in Kaohsiung. VoIP users should also use the standard international format to ensure proper routing.

In summary, the +886 71 code is a reliable indicator of a fixed-line number in Kaohsiung, Taiwan. Whether you are placing a local call or an international one, following the correct dialing format ensures successful connection.
