Area Code 555 – MaAnshan, Anhui

Overview of +86 555

The country calling code +86 is assigned to the People's Republic of China under the ITU-T E.164 international numbering plan. Within this framework, the national destination code (NDC) 555 is a geographic area code that routes calls to the city of Ma'anshan (马鞍山), located in the eastern province of Anhui. Ma'anshan is a prefecture-level city situated on the southern bank of the Yangtze River, bordering Jiangsu province. It is an important industrial hub, particularly known for its steel production, and administers several districts and counties, including Yushan, Huashan, Bowang, Dangtu, Hanshan, and He County.

Dialing Formats

When calling a fixed-line number in Ma'anshan from within China, the domestic trunk prefix 0 is used, followed by the area code 555 and the local subscriber number. The complete domestic format is 0 555 XXXX XXXX (where X represents the 7- or 8-digit local number). For example, a typical local number might be 0555 234 5678.

From outside China, callers must use the international access prefix of their country (e.g., 011 in the US, 00 in most European countries), followed by China's country code 86, the area code without the leading zero, and the local subscriber number. Thus, an international call to the same number would be dialed as +86 555 234 5678.

Local and International Calling Instructions

For callers within Ma'anshan, local calls can be made by dialing the local subscriber number directly, without the area code. However, when calling from other cities in China, the full domestic format with the trunk prefix 0 must be used. For international callers, it is essential to omit the leading '0' of the area code when dialing after the country code. Failure to do so will result in a routing error.

Geographic Significance and Numbering

As a geographic code, 555 is allocated exclusively to fixed-line services in the Ma'anshan region. Mobile numbers in China are not tied to geographic areas and begin with distinct prefixes such as 13x, 15x, 18x, etc., and are dialed as +86 1XX XXXX XXXX internationally. The area code 555 is not used for mobile services. Overlay codes are not currently in effect for Ma'anshan; the city retains a single area code for all fixed-line subscribers.

When dialing from abroad, always check the current dialing procedures for your country, as some international carriers may require different access codes. For businesses and individuals in Ma'anshan, ensuring that international callers have the correct number format is crucial for seamless connectivity.
