📍 Geographic Location of Weihai, Shandong
Overview of +86 631
The country calling code +86 belongs to the People's Republic of China, and the area code 631 is assigned to the city of Weihai (威海) in Shandong Province. This is a geographic National Destination Code (NDC) under the ITU-T E.164 numbering plan. Weihai is a major port city located on the northeastern coast of the Shandong Peninsula, facing the Yellow Sea and the Korea Bay. It administratively includes the central urban districts of Huancui, Wendeng, and Rongcheng, as well as Rushan county-level city.
Geographic Coverage and Dialing Format
The +86 631 prefix covers all landline telephone numbers in Weihai's administrative region. Local calls within Weihai are made using the 8-digit subscriber number alone, without the area code. For calls from other parts of China, the format is 0-631-XXXX XXXX, where the leading 0 is the domestic trunk prefix. International callers must dial +86 631 XXXX XXXX (or 0086 631 XXXX XXXX from many countries), omitting the leading 0. The total number length after the country code is 11 digits (including the 631 area code).
Numbering and Overlay Considerations
Weihai's telephone numbers are 8 digits long, following the standard for major Chinese cities. As of the latest updates, there is no overlay code for Weihai; 631 remains the sole area code for the region. The numbering plan is closed, meaning the area code must be dialed for all calls from outside the local area, even for numbers within the same province.
Caller Instructions
- Local callers (within Weihai): Simply dial the 8-digit subscriber number.
- Domestic long-distance callers (from other Chinese cities): Dial 0-631 followed by the 8-digit number.
- International callers: Dial your country's exit code (e.g., 00, 011), then 86, then 631, then the 8-digit number. For example, from the US, dial 011 86 631 XXXX XXXX.
Mobile numbers in China do not use geographic area codes; they begin with 13x to 19x and are not affected by the 631 prefix. When calling a Weihai landline from a mobile phone, the same dialing rules apply.
