📍 Geographic Location of YaAn, Sichuan
Geographic Overview
The +86 835 area code is a geographic National Destination Code (NDC) assigned to Ya'an (雅安), a prefecture-level city located in the western part of Sichuan Province, China. Ya'an is historically significant as the former capital of Xikang Province and is now a key transportation hub on the route to Tibet. The area code covers the entire administrative jurisdiction of Ya'an, including its urban districts (Yucheng and Mingshan) and all surrounding counties and county-level cities, such as Yingjing, Hanyuan, Shimian, Tianquan, and Baoxing.
Dialing Formats
When calling a fixed-line number in Ya'an from within China, the trunk prefix 0 is used before the area code, followed by the local subscriber number. Local numbers in Ya'an are typically 7 digits long, making the complete domestic dialing format: 0 835 XXXX XXX (e.g., 0 835 123 4567). For international callers, the country code +86 is used, and the leading trunk prefix 0 is dropped, resulting in the international format: +86 835 XXXX XXX (e.g., +86 835 123 4567).
Caller Instructions
- Domestic callers outside Ya'an: Dial 0 835 followed by the 7-digit local number.
- Local callers within Ya'an: In most cases, the area code and trunk prefix can be omitted, and only the 7-digit subscriber number is dialed. However, due to the implementation of closed numbering plans in some regions, it is advisable to check local carrier guidelines.
- International callers: Dial the international access prefix of your country (e.g., 011 from the US), then China's country code 86, then 835, and finally the 7-digit local number. Do not dial the trunk prefix 0.
Overlay and Numbering Considerations
Currently, no overlay area code has been assigned to Ya'an. The 835 area code is exclusively used for geographic fixed-line services, including PSTN and fixed VoIP lines. Mobile numbers in China are assigned separate non-geographic prefixes (e.g., 13x, 15x, 18x) and are not affected by this area code. As China's telecommunications regulator (MIIT) continues to manage numbering resources, future changes such as number portability or overlay codes may occur, but as of the latest updates, 835 remains the sole area code for Ya'an.
For businesses and residents, it is essential to use the correct dialing format to ensure successful call routing. When publishing contact numbers, always include the area code in international format (+86 835) to facilitate calls from overseas.
