📍 Geographic Location of Shenzhen, Guangdong
Geographic Overview
Area code 755 is the National Destination Code (NDC) assigned to Shenzhen, a major city in Guangdong Province, China. Shenzhen is a Special Economic Zone and one of the country's most dynamic metropolitan centers, bordering Hong Kong. The code covers the entire administrative area of Shenzhen, including central districts such as Futian, Luohu, Nanshan, Yantian, and Bao'an, as well as the newer districts of Longgang, Longhua, Pingshan, Guangming, and Dapeng New Area.
Dialing Formats
When calling a fixed-line number in Shenzhen from within China, the domestic trunk prefix 0 is used before the area code, followed by the 8-digit local subscriber number. The full domestic format is: 0 755 XXXX XXXX. For example, a local Shenzhen number might be dialed as 0755 1234 5678 from elsewhere in China.
For international callers, the country code for China (+86) replaces the trunk prefix. The international format is: +86 755 XXXX XXXX. Thus, the same number would be dialed as +86 755 1234 5678 from outside China. Note that the leading '0' is not used in international dialing.
Local and Regional Calling
Within Shenzhen, local calls are made by dialing only the 8-digit subscriber number; the area code is not required. However, due to the city's size and the integration of mobile and fixed networks, it is common practice to include the area code even for local calls, especially when calling from mobile phones. For calls from other parts of Guangdong Province, the trunk prefix and area code (0755) are still required, as Shenzhen is a separate local call area.
Numbering and Overlays
Shenzhen uses an 8-digit subscriber numbering plan, which was implemented in 2002 to meet growing demand. There are no overlay codes currently in use; 755 remains the sole geographic area code for the city. All fixed-line numbers in Shenzhen begin with digits 2 through 9, with certain ranges allocated to specific services. For instance, numbers starting with '8' are often associated with businesses, while '2' to '7' may include residential and corporate lines.
Practical Guidance for Callers
For local callers within Shenzhen, simply dial the 8-digit number. For domestic long-distance calls from other Chinese cities, dial 0755 followed by the subscriber number. For international callers, always use the +86 country code and omit the leading '0'. Ensure you have the correct 8-digit local number, as omitting or adding digits will result in a failed call.
