📍 Geographic Location of Kaili, Guizhou
Geographic Overview
The area code 855 is a geographic National Destination Code (NDC) assigned to Kaili, the capital city of the Qiandongnan Miao and Dong Autonomous Prefecture in Guizhou Province, China. This code is part of the broader Chinese numbering plan under the country calling code +86, as defined by ITU-T E.164. Kaili serves as the political, economic, and cultural center of the prefecture, with a population of approximately 500,000 in the urban core. The region is known for its rich ethnic diversity, particularly the Miao and Dong minorities, and is a popular destination for cultural tourism.
Dialing Formats
For callers within China, the domestic long-distance format is used: dial 0855 followed by the local 7-digit subscriber number. For example, a local number in Kaili might be 1234567, and a domestic caller from Beijing would dial 0855 1234567. For international callers, the format is +86 855 1234567 (or 0086 855 1234567 from many countries). Note that the leading '0' of the domestic prefix is omitted when dialing from abroad.
Geographic Coverage
The 855 area code covers not only the city of Kaili but also the surrounding counties and districts within the Qiandongnan Prefecture. This includes major towns such as Huangping, Shibing, Sansui, Zhenyuan, Cengong, Tianzhu, Jinping, Jianhe, Taijiang, Liping, Rongjiang, Congjiang, and Danzhai. The region is predominantly mountainous, and the telecommunications infrastructure has been developed to provide reliable PSTN and mobile services across the area.
Numbering and Overlay Considerations
Local numbers in Kaili are 7 digits long, resulting in a total of 10 digits for domestic calls (including the leading '0') and 11 digits for international calls (including the country code). As of now, there is no overlay plan for the 855 area code; the region has not required an additional NDC due to sufficient numbering capacity. However, as the region develops, the telecommunications regulator (MIIT) may introduce changes, so it is advisable to verify current dialing procedures.
Caller Instructions
Local callers within the 855 area code can dial the 7-digit subscriber number directly without the area code. Domestic long-distance callers must prefix the area code with '0' (i.e., 0855). International callers should use the country code +86, followed by the area code without the leading '0', and then the subscriber number. For example, to call a Kaili number from the United States, one would dial 011 86 855 1234567. It is important to note that China uses the international dialing prefix '00' in many countries, but the '+' sign is universally recognized on mobile phones.
