Area Code 662 – Yangjiang, Guangdong

Overview of Area Code +86 662

Area code 662 is a geographic National Destination Code (NDC) assigned to Yangjiang, a prefecture-level city located in the southwestern coastal region of Guangdong Province, China. This code is part of the Chinese numbering plan administered under ITU-T E.164, where the country calling code for China is +86. The 662 area code covers the urban districts of Yangjiang, including Jiangcheng, as well as the surrounding county-level cities of Yangchun and Yangdong, and the county of Yangxi.

Geographic Coverage and Administrative Jurisdiction

Yangjiang is situated along the South China Sea coast, approximately 200 kilometers southwest of Guangzhou, the provincial capital. The area code serves a population of over 2.5 million residents across a mix of urban and rural areas. Key cities and towns within the 662 numbering area include the central urban area of Yangjiang, the industrial city of Yangchun, and the port town of Zhapo, which is known for its fishing industry and tourism. The region is part of the Pearl River Delta economic zone, though it is less densely populated than core delta cities.

Dialing Formats and Instructions

For local callers within Yangjiang (i.e., when dialing a number that shares the 662 area code), the standard local format is an 8-digit subscriber number. To call another local number, you simply dial the 8-digit number without any prefix. However, when calling from outside the 662 area but still within China, you must dial the trunk prefix 0 followed by the area code and the subscriber number: 0 662 XXXX XXXX. For example, a local number in Yangjiang might be 0662 1234 5678 when dialed from elsewhere in China.

For international callers, the dialing format is: +86 662 XXXX XXXX. The leading zero is omitted when dialing from abroad. For instance, to call a Yangjiang landline from the United States, you would dial 011 86 662 1234 5678 (or +86 662 1234 5678 from a mobile phone).

Overlay and Numbering Considerations

As of the latest updates, there is no overlay code for Yangjiang; 662 remains the sole area code for the region. All fixed-line subscriber numbers in Yangjiang are 8 digits long, and the total length of a national significant number (NSN) for a fixed-line call is 11 digits (including the leading 0). This is consistent with China's national numbering plan, where fixed-line numbers are typically 10 or 11 digits in length.

Callers should note that while mobile numbers in China also start with 1 (e.g., 13X, 15X, 18X), they are not tied to geographic area codes. Therefore, a mobile number with a prefix like 138 or 186 does not indicate a Yangjiang location. Always use the full national or international format when dialing to ensure correct routing.
