📍 Geographic Location of Longyan, Fujian
Geographic Overview
Area code 597 is a geographic National Destination Code (NDC) assigned to Longyan (龙岩), a prefecture-level city located in the western part of Fujian Province, China. Longyan is known for its mountainous terrain, historic Hakka tulou (earthen buildings), and as a significant revolutionary base. The city administers two districts (Xinluo and Yongding) and four counties (Changting, Liancheng, Shanghang, and Wuping). The area code covers the entire prefecture, including urban and rural areas.
Dialing Formats
When calling a fixed-line number in Longyan from within China, you must dial the trunk prefix 0 followed by the area code 597 and the local subscriber number. For example, a local number in Xinluo District might be 1234567, so the domestic dialing format is 0597 1234567. From outside China, you would dial the international access code (e.g., 00 or +), then China's country code 86, followed by the area code without the leading zero, and the subscriber number: +86 597 1234567.
Caller Instructions
- Local callers within Longyan: For calls to another fixed-line number in the same area, local dialing rules may allow omitting the area code and trunk prefix, but it is safer to always use the full domestic format 0597-XXXXXXX to avoid confusion.
- Domestic callers from other cities in China: Dial 0597 followed by the subscriber number.
- International callers: Dial your country's exit code (e.g., 011 from the US, 00 from most European countries), then 86, then 597, and the subscriber number. Do not dial the leading '0'.
Numbering and Overlays
Fixed-line subscriber numbers in Longyan typically consist of 7 digits, making the total length of a domestic number (including trunk prefix and area code) 11 digits. As of the latest ITU-T E.164 assignment, no overlay codes have been introduced for Longyan; the 597 code remains the sole geographic code for the region. However, with the growth of telecommunications services, some numbers may be used for non-geographic services, but the area code itself is strictly geographic.
Regulatory and Technical Notes
The Ministry of Industry and Information Technology (MIIT) of China oversees the allocation of numbering resources. Area code 597 is part of the national numbering plan, which uses the open dialing plan with trunk prefix '0'. For VoIP and mobile services, numbers are assigned separately and are not tied to geographic location. When calling a Longyan fixed-line number from a mobile phone, the same dialing rules apply. It is important to note that China has implemented number portability for mobile and fixed-line services, but the geographic significance of the area code remains for routing and tariff purposes.
