Area Code 29 – XiAn/Xianyang, Shaanxi

Overview of Area Code +86 29

Area code 29 is the geographic country calling code for the central part of Shaanxi Province in the People's Republic of China. It serves the provincial capital Xi'an (西安) and the neighboring city of Xianyang (咸阳), as well as their surrounding administrative districts. Under the ITU-T E.164 international numbering plan, the full international dialing format for a fixed-line number in this region is +86 29 XXXX XXXX, where the subscriber number is eight digits long. The national trunk prefix '0' is used when dialing domestically, resulting in the format 0-29-XXXX XXXX.

Geographic Coverage and Administrative Jurisdiction

The 29 area code is allocated to the Xi'an–Xianyang metropolitan area, which forms the economic and cultural heart of Shaanxi. Xi'an, the largest city in Northwest China, is known for its historical significance as the starting point of the Silk Road and the home of the Terracotta Army. Xianyang, located just northwest of Xi'an, is an integral part of the same urban agglomeration and shares the same numbering area. The code also covers several counties and districts under the jurisdiction of these two prefecture-level cities, including but not limited to Lintong, Chang'an, and Weiyang districts of Xi'an, and Qindu and Weicheng districts of Xianyang.

Dialing Formats and Caller Instructions

For callers within China, dialing a fixed-line number in this area requires the trunk prefix '0' followed by the area code and the eight-digit local number: 0-29-XXXX XXXX. For example, a local call from Beijing to Xi'an would be dialed as 029-XXXX XXXX. For international callers, the process involves dialing the international access prefix (e.g., '00' from most countries, or '+' from mobile phones), followed by China's country code 86, then the area code 29 (without the leading '0'), and finally the eight-digit subscriber number. Thus, an international caller would dial +86 29 XXXX XXXX.

Overlay and Numbering Considerations

As of the current numbering plan, there is no overlay code for the 29 area; the region uses a single area code. However, due to the rapid growth of telecommunications in the region, the demand for new fixed-line numbers has been met by expanding the range of eight-digit subscriber numbers. It is important to note that mobile numbers in China are not tied to geographic area codes; they use the 1xx prefixes (e.g., 13x, 15x, 18x) and are dialed as +86 1XX XXXX XXXX internationally, without the area code. When calling a fixed-line number from a mobile phone within China, the same trunk prefix and area code rules apply.

For businesses and individuals, understanding the correct dialing format is essential for reliable connectivity. Whether you are placing a call from abroad or within China, using the proper country code, area code, and subscriber number ensures your call reaches the intended destination in Xi'an or Xianyang.
