Area Code 856 – Tongren, Guizhou

Overview of Area Code 856

Area code 856 is a geographic telephone prefix assigned to Tongren City (铜仁市) in Guizhou Province, China. It is part of the national numbering plan under the country code +86. The code serves a prefecture-level city located in the eastern part of Guizhou, bordering Hunan Province. Tongren is known for its scenic landscapes, including the Fanjingshan (Mount Fanjing) UNESCO World Heritage Site, and is an important transportation hub in the region.

Coverage and Administrative Jurisdiction

The 856 area code covers the entire administrative area of Tongren City, including its urban districts and surrounding counties. Key administrative divisions under this code include:

• Bijiang District (碧江区) – the central urban area and seat of the municipal government
• Wanshan District (万山区)
• Songtao Miao Autonomous County (松桃苗族自治县)
• Yanhe Tujia Autonomous County (沿河土家族自治县)
• Sinan County (思南县)
• Dejiang County (德江县)
• Yinjiang Tujia and Miao Autonomous County (印江土家族苗族自治县)
• Shiqian County (石阡县)
• Jiangkou County (江口县)
• Yuping Dong Autonomous County (玉屏侗族自治县)

These areas are served by fixed-line telephone networks, including PSTN and VoIP services, with numbers typically 8 digits long after the area code.

Dialing Formats

Understanding the correct dialing format is crucial for both domestic and international callers.

• Local calls within Tongren: For calls within the same area code, dial the 8-digit subscriber number directly (e.g., 12345678).
• Domestic long-distance calls from other Chinese cities: Dial the trunk prefix 0 followed by the area code and subscriber number: 0 856 12345678.
• International calls from outside China: Dial the international access prefix (e.g., 011 from the US, 00 from many countries) followed by China's country code 86, the area code (without the leading 0), and the subscriber number: +86 856 12345678.

For example, to call a fixed line in Tongren from abroad, you would dial +86 856 12345678 (replace 12345678 with the actual 8-digit number).

Overlay and Numbering Considerations

Currently, there is no overlay code for Tongren; 856 is the sole area code for the region. However, as with all Chinese geographic codes, the leading 0 is only used for domestic trunk calls and is omitted when dialing from abroad. Mobile numbers in China are not tied to geographic area codes and begin with 13x to 19x, so they are dialed as +86 followed by the 11-digit mobile number.

Caller Instructions

For local callers within Tongren, simply dial the 8-digit number. For callers from other parts of China, always include the trunk prefix 0 and the area code 856. For international callers, use the plus sign (+) or the appropriate international prefix, then 86 and 856. Ensure you omit the leading 0 when dialing from abroad. This format ensures proper routing through the PSTN and VoIP networks.
