Area Code 823 – Kinmen

Overview of Taiwan Area Code 823

Area code 823 is a geographic National Destination Code (NDC) assigned to the Kinmen archipelago, an island group administered by the Republic of China (Taiwan). Located in the Taiwan Strait, Kinmen comprises several islands, with the main island also named Kinmen. The code serves the entire county, including the administrative capital Jincheng, as well as Jinsha, Jinhu, Jinning, and Lieyu (also known as Lesser Kinmen).

Dialing Formats

When calling a fixed-line number in Kinmen from within Taiwan, subscribers dial the trunk prefix '0' followed by the area code 823 and the subscriber's 6- or 7-digit local number. For example, a local number such as 372123 would be dialed as 0823 372123 from other parts of Taiwan, or simply 823 372123 if using a mobile phone (where the leading '0' is often omitted).

For international callers, the Taiwan country code (+886) is used, and the leading '0' of the area code is dropped. Thus, the same number would be dialed as +886 823 372123 from abroad.

Geographic and Administrative Coverage

Kinmen County is a special municipality under the ROC government, with its own county magistrate. The area code 823 is used for all landline telephones within the county, including those in the outlying islands of Wuqiu (which are also part of Kinmen County). The code is not overlaid with any other area code, and all fixed-line numbers within the county share the same NDC.

Caller Instructions

For local callers within Kinmen, dialing the 6- or 7-digit subscriber number directly (without the area code) is sufficient for local calls. However, when calling from a mobile phone, it is common practice to include the area code (e.g., 0823) to avoid ambiguity, as mobile numbers in Taiwan are not tied to geographic areas.

For callers from other regions in Taiwan, the full national format (0-823-XXXXXX) is required. For international callers, the format is +886-823-XXXXXX. It is important to note that the leading '0' is only used within Taiwan's domestic dialing plan; it is not included when dialing from overseas.

Regulatory and Technical Notes

The area code 823 is allocated under the National Communications Commission (NCC) of Taiwan, following ITU-T E.164 recommendations. As of the latest updates, Kinmen has not implemented number portability for fixed-line services, meaning that the area code remains tied to the physical location of the line. However, VoIP services may allow users to obtain a Kinmen number without being physically present, but such numbers are still subject to the same dialing rules.
