Area Code 598 – Sanming, Fujian

Overview of Area Code 598

Area code 598 is a geographic telephone code assigned to Sanming, a prefecture-level city located in the western part of Fujian Province, China. Under the national numbering plan, this code is part of the +86 country calling code and is used for fixed-line (PSTN) services within the designated administrative region. Sanming is an important industrial and transportation hub, with districts such as Meilie, Sanyuan, and Sha County, as well as county-level cities like Yong'an, all falling under this numbering area.

Dialing Formats

For callers within China, the local dialing format for Sanming numbers is 0598-XXXXXXX, where the leading '0' is the domestic trunk prefix. When calling from outside China, the international format becomes +86 598 XXXX XXX, omitting the trunk prefix '0'. For example, a local Sanming number might be 0598-8321234, which would be dialed as +86 598 8321234 from abroad. It is important to note that the total length of a Chinese fixed-line number, including the area code, is typically 11 or 12 digits, and the subscriber number length can vary between 7 and 8 digits depending on the specific exchange and capacity.

Geographic Coverage and Administration

The 598 area code serves the entire administrative jurisdiction of Sanming City, which includes two districts (Meilie, Sanyuan), one county-level city (Yong'an), and eight counties (Mingxi, Qingliu, Ninghua, Datian, Youxi, Jianning, Taining, and Jiangle). This allocation is managed by the Ministry of Industry and Information Technology (MIIT) and the local telecommunications administration. The code is strictly geographic, meaning that the number is tied to a physical location, and calls are routed based on the destination exchange.

Overlays and Number Portability

Currently, there is no overlay code for Sanming; 598 remains the sole area code for the region. However, China has implemented mobile number portability (MNP) for mobile services, but fixed-line numbers are generally not portable between different geographic areas. For fixed-line subscribers, changing location within the same area code is possible without changing the number, but moving outside the 598 region would require a new number.

Caller Instructions

For local callers within Sanming, dialing another fixed-line number in the same area code typically requires only the 7- or 8-digit subscriber number, without the area code. However, for clarity and to avoid misdialing, it is common to include the area code even for local calls. For callers from other regions in China, dial 0598 followed by the subscriber number. For international callers, dial your country's exit code (e.g., 011 from the US, 00 from most countries), then 86, then 598, and finally the subscriber number. Always ensure you drop the leading '0' of the area code when dialing internationally.
