📍 Geographic Location of Taiyuan, Shanxi
Geographic Overview
The area code 351 is the designated National Destination Code (NDC) for the city of Taiyuan, the capital and largest metropolis of Shanxi Province in the People's Republic of China. Under the ITU-T E.164 international numbering plan, the full country calling code for China is +86. Therefore, to reach a fixed-line subscriber in Taiyuan from abroad, you would dial +86 351 followed by the local 7-digit subscriber number. Within China, the trunk prefix '0' is used before the area code, so domestic long-distance calls require dialing 0351 followed by the 7-digit number.
Geographic Coverage and Administrative Jurisdiction
The 351 numbering area encompasses the entire administrative territory of Taiyuan, which includes its six urban districts (Xiaodian, Yingze, Xinghualing, Jiancaoping, Wanbailin, and Jinyuan), as well as the three counties (Qingxu, Yangqu, and Loufan) and the county-level city of Gujiao. This allocation is managed by the Shanxi Provincial Communications Administration under the Ministry of Industry and Information Technology (MIIT). As a geographic code, 351 is permanently associated with the Taiyuan PSTN (Public Switched Telephone Network) and is not portable to other regions.
Dialing Formats and Caller Instructions
- Local calls within Taiyuan: When dialing a number within the same area code, only the 7-digit subscriber number is required. For example, to call a local landline, simply dial 1234567.
- Domestic long-distance calls from other Chinese cities: Dial the trunk prefix 0, then the area code 351, followed by the 7-digit subscriber number. Example: 0351 1234567.
- International calls from abroad: Dial the international access prefix (e.g., 00 from most countries, or '+' from mobile phones), then China's country code 86, the area code 351 (without the leading '0'), and the 7-digit subscriber number. Example: +86 351 1234567.
Overlay and Numbering Considerations
As of the latest MIIT updates, the 351 area code does not have an overlay code. The 7-digit subscriber numbering capacity provides sufficient numbers for the region's fixed-line demand. However, with the increasing adoption of VoIP and mobile services, some businesses may use non-geographic numbers for customer service lines, but these are not part of the 351 geographic allocation.
Important Notes for Callers
When dialing from a mobile phone within China, the same domestic long-distance format (0-351-XXXXXXX) applies. For international callers, it is crucial to omit the trunk prefix '0' when dialing the area code. Additionally, while most fixed-line numbers in Taiyuan are 7 digits, some older or specialized services might have different lengths; always verify the complete number with the recipient.
