Overview of Area Code +86 58
The telephone country code +86 belongs to China, and the prefix 58 is a geographic area code assigned to the city of Zhoushan, located in Zhejiang Province. Zhoushan is a prefecture-level city and the only city in China composed primarily of islands, with its urban center on Zhoushan Island. The area code 58 covers the entire administrative region of Zhoushan, including its four districts: Dinghai, Putuo, Daishan, and Shengsi. These districts encompass both the main island and numerous outlying islands, serving a population of over one million residents.
Dialing Formats and Usage
For callers within China, dialing a Zhoushan landline requires the national trunk prefix 0 followed by the area code and the local subscriber number. For example, a local Zhoushan number such as 1234567 would be dialed as 0581 1234567 from other parts of China. However, when calling from outside China, the international access prefix (00 or +) is used, followed by the country code 86, the area code without the leading zero, and the subscriber number. Thus, the same number would be dialed as +86 581 1234567 from abroad. It is essential to note that the area code is 58, but when dialed internationally, the leading zero is dropped, leaving 581 as the national destination code (NDC).
Geographic Coverage and Administrative Jurisdiction
Zhoushan's numbering plan is administered under the jurisdiction of the Ministry of Industry and Information Technology (MIIT) of China. The area code 58 is exclusively assigned to Zhoushan, and no overlay codes are currently in effect. This means that all landline numbers within Zhoushan share the same area code, and no changes are required for local dialing. The city is known for its fishing industry, ports, and the Zhoushan Archipelago New Area, a national-level strategic zone. Major towns and ports within the coverage area include Dinghai, Putuo, and the scenic island of Shengsi.
Caller Instructions
For local callers within Zhoushan, dialing a landline number typically requires only the seven-digit subscriber number. However, for callers from other parts of China, the full national format (0 + area code + number) is mandatory. International callers must use the +86 581 format. It is also important to note that mobile phone numbers in China have their own prefixes (e.g., 130-189) and are not affected by geographic area codes. When calling a Zhoushan landline from a mobile phone, the same dialing rules apply as for landline calls.
