Area Code 599 – Nanping, Fujian

Overview of Area Code +86 599

Area code 599 is a geographic destination code within the People's Republic of China's national numbering plan, assigned to Nanping (南平), a prefecture-level city in the northwestern part of Fujian Province. Under the ITU-T E.164 international standard, the full international dialing format for a fixed-line number in Nanping is +86 599 XXX XXXX (or +86599XXXXXXXX), where the country code +86 is followed by the area code 599 and the local subscriber number. The local number length is typically 7 digits, resulting in a total national significant number (NSN) length of 11 digits, excluding the international prefix.

Geographic Coverage and Administrative Jurisdiction

The 599 area code serves the entire administrative region of Nanping, which includes the central urban districts of Yanping (延平) and Jianyang (建阳), as well as the county-level cities of Shaowu (邵武), Wuyishan (武夷山), and Jian'ou (建瓯), and the counties of Shunchang (顺昌), Pucheng (浦城), Guangze (光泽), Songxi (松溪), and Zhenghe (政和). Nanping is known for its scenic Wuyi Mountains, a UNESCO World Heritage Site, and is a major tea-producing area. The area code is exclusively used for fixed-line PSTN and VoIP services in this region; mobile numbers in China are assigned separate non-geographic prefixes (e.g., 13x, 15x, 18x) and are not tied to this area code.

Dialing Procedures

Local calls within Nanping: When dialing a fixed-line number from another fixed-line or mobile phone within the same area code, callers typically dial only the 7-digit subscriber number (e.g., 1234567). However, some mobile users may be required to include the area code depending on carrier settings.

Domestic long-distance calls from other parts of China: Callers must dial the national trunk prefix 0 followed by the area code and subscriber number: 0599 XXX XXXX (e.g., 0599 1234567).

International calls from outside China: Callers should dial their country's international access prefix (e.g., 011 from the US, 00 from most European countries), followed by China's country code 86, the area code 599, and the subscriber number: +86 599 1234567 (or +865991234567).

Numbering Plan Considerations

China's numbering plan is regulated by the Ministry of Industry and Information Technology (MIIT). The 599 area code is a closed numbering plan for fixed-line services, meaning that the subscriber number length is fixed. As of the current plan, there is no overlay area code for Nanping; the 599 code is the sole geographic code for the region. However, with the increasing adoption of VoIP and number portability, some numbers may be routed over IP networks, but the geographic significance of the code remains for regulatory and emergency services (e.g., police 110, ambulance 120).

For callers, it is essential to use the correct prefix to avoid misrouting. When dialing from abroad, omitting the leading '0' of the domestic trunk prefix is mandatory; the international format requires only +86 and the area code without the '0'. For example, the domestic number 0599 1234567 becomes +86 599 1234567 internationally.
