Area Code 83 – Matsu

Overview of Area Code +886 83

Area code 83 is a geographic National Destination Code (NDC) assigned to the Matsu Islands (Lienchiang County), an archipelago administered by the Republic of China (Taiwan). Matsu is located in the Taiwan Strait, approximately 190 kilometers northwest of the main island of Taiwan. The code covers the principal islands of Nangan, Beigan, Dongju, and Xiju, along with their smaller islets. The administrative center is Nangan Township, where the Lienchiang County Government is situated.

Geographic Coverage and Dialing Formats

The +886 83 area code serves all fixed-line telephone services in Matsu, including residential, business, and government lines. Key population centers include Nangan (Magong), Beigan, and the smaller islands. When dialing from within Taiwan, callers must use the trunk prefix 0 followed by the area code and the subscriber number. The local subscriber number for Matsu is typically 6 digits long, resulting in the format: 0 83 X XXX XXX (total 9 digits after the trunk prefix). For example, a number in Nangan might appear as 0 83 25 1234.

For international callers, the Taiwan country code +886 replaces the trunk prefix, and the leading zero of the area code is dropped. The international dialing format becomes +886 83 X XXX XXX. For instance, to call a Matsu number from the United States, one would dial 011 886 83 25 1234 (or +886 83 25 1234 from a mobile phone).

Calling Instructions and Overlay Considerations

When calling from outside Taiwan, always replace the leading '0' of the area code with the international access code and Taiwan's country code. For example, from the UK, dial 00 886 83 25 1234. From within Taiwan, simply dial 0 83 25 1234.

Currently, there is no overlay code for the Matsu area; the 83 code is exclusively used for fixed-line services. Mobile numbers in Matsu are not tied to this geographic code; they use non-geographic mobile prefixes such as 0905, 0910, etc., and can be reached by dialing the full 10-digit mobile number (e.g., 0912 345 678).

Practical Tips for Callers

• If you are calling a Matsu number from a mobile phone in Taiwan, you can dial the number with or without the trunk prefix '0', but using the full national format is recommended.
• For international callers, ensure you have the correct country code (+886) and omit the leading '0' of the area code.
• Some businesses in Matsu may use VoIP or non-geographic numbers for customer service; these numbers may have different dialing patterns.
