Overview of +86 859
The country calling code +86 is assigned to the People's Republic of China under the ITU-T E.164 international numbering plan. The national destination code (NDC) 859 is a geographic area code that routes calls to the city of Xingyi (兴义市), located in the Qianxinan Buyei and Miao Autonomous Prefecture (黔西南布依族苗族自治州) in the southwestern part of Guizhou Province. This code is used for fixed-line (PSTN) services within the city and its surrounding administrative areas.
Geographic Coverage and Dialing Formats
The 859 area code covers Xingyi city proper, as well as the counties and towns under the jurisdiction of Qianxinan Prefecture, including Xingren, Pu'an, Qinglong, Zhenfeng, Wangmo, Ceheng, and Anlong. For local calls within the 859 region, subscribers dial only the 7-digit local subscriber number (e.g., 1234567). For domestic long-distance calls from other parts of China, callers must dial the trunk prefix 0 followed by the area code and the local number: 0 859 1234567. From outside China, the international access prefix (00 or +) is used, followed by the country code 86, the area code 859 without the leading 0, and the local number: +86 859 1234567.
Important Dialing and Regulatory Notes
As of the latest numbering plan updates, the 859 area code does not have an overlay code; therefore, all fixed-line numbers in Xingyi share the same 7-digit length. Mobile numbers in China are assigned distinct non-geographic prefixes (e.g., 13x, 15x, 18x) and are not affected by this area code. When calling from abroad, ensure that you omit the trunk prefix '0' and use the international format. For callers within China, note that the leading '0' is only used for domestic long-distance calls; local calls do not require it. All fixed-line numbers in the 859 region are allocated by China Telecom and China Unicom, the primary fixed-line operators in Guizhou.
For businesses and individuals, understanding the correct dialing format is essential to avoid call failures or misrouting. Always verify the local number length, as some older numbers may have been migrated to 8 digits in other Chinese cities, but Xingyi retains 7-digit local numbers. If you are using VoIP or mobile services, ensure that your service provider supports calls to geographic Chinese numbers and that you have the correct international dialing prefix for your country.
