Area Code 75 – Kaohsiung

Geographic Overview

The +886 75 prefix is the National Destination Code (NDC) for Kaohsiung, Taiwan's largest port city and second most populous municipality. This geographic code covers the entire Kaohsiung metropolitan area, including the historic city center, the port districts, and the surrounding administrative regions such as Fengshan, Cianjhen, Lingya, and the more remote mountain and coastal districts. As a geographic number, the prefix is tied to a specific physical location, and calls to +886 75 are routed to landline telephones within the Kaohsiung local exchange area.

Dialing Formats

When dialing a Kaohsiung landline from within Taiwan, the national trunk prefix '0' is used, followed by the area code (with the leading '0' included) and the subscriber number. For example, a local Kaohsiung number might be dialed as 07 1234 5678. Note that within the same area code, callers may often omit the area code and dial just the 7- or 8-digit subscriber number, depending on the local exchange. However, for clarity and consistency, it is recommended to always include the area code when dialing from a mobile phone or from outside the region.

For international callers, the format is: +886 7 1234 5678 (or +886 75 1234 5678 if the subscriber number includes the leading digit of the old 7-digit numbering plan). The plus sign represents the international access code, which varies by country (e.g., 011 from the US, 00 from most European countries). The leading '0' of the national trunk prefix is dropped when dialing from abroad.

Numbering Plan and Overlays

Taiwan's numbering plan is regulated by the National Communications Commission (NCC). The Kaohsiung area code is part of the original geographic numbering scheme, and in recent years, the NCC has introduced number portability and overlay codes to address demand. However, as of the latest updates, Kaohsiung continues to use the 07 area code (with the international prefix +886 7). The prefix '75' is not an overlay but rather a part of the subscriber number range within the 07 area code. For instance, a number like +886 75 123 4567 is a valid landline number in Kaohsiung, where '5' is the first digit of the subscriber number.

When dialing locally, if you are within the Kaohsiung area, you may dial the subscriber number without the area code, but this practice is becoming less common due to the proliferation of mobile phones and VoIP services. Always check with your service provider for the correct dialing procedure.

Caller Instructions

For local callers within Taiwan: dial 0 7 1234 5678 (including the trunk prefix '0'). For mobile callers in Taiwan, it is safe to always include the area code. For international callers: dial your country's exit code, then 886 7 1234 5678. For example, from the United States, you would dial 011 886 7 1234 5678. From the United Kingdom, dial 00 886 7 1234 5678.

Kaohsiung is a major economic hub, and many businesses and government offices use these landline numbers. When contacting Taiwanese businesses, be aware that they may also provide mobile numbers, which have different prefixes (e.g., 09xx). Always confirm the correct number format to avoid misdialing.
