Nanchang area code

Nanchang is located in the east of China, north of central Jiangxi Province, downstream of Ganjiang River and Fuhe River, and southwest of Poyang Lake. It is the political, economic, cultural, scientific, educational and transportation center of Jiangxi Province. Since ancient times, it has been known as "Guangdong households and Fujian courts, Wu Tou Chu Wei" and "five lakes and three rivers".

The land of "controlling barbarians and attracting Ouyue" is the only provincial capital center city in China adjacent to the Yangtze River Delta, Pearl River Delta and the economic zone on the west side of the Taiwan Strait. It is also one of the important central cities in East China and the middle reaches of the Yangtze River. ?

A brief history of area code development:

The area code was determined after the Cultural Revolution. At that time, there was no program-controlled telephone exchange, and there were not many municipal administrative units (mostly regions and few prefecture-level cities). When the local unit exceeds 10 but is less than 15, some areas with less long-distance telecom business share a regional switching center.

For example, Huaihua City in Hunan Province, Xiangxi Tujia and Miao Autonomous Prefecture in Hunan Province and Zhangjiajie City in Hunan Province share a regional exchange center with neighboring Chenzhou and Loudi cities in Hunan Province, so the area code is 4. However, the long-distance network also adopts the "multilevel tandem system".

In the 1990s, computer-controlled program-controlled switches were widely used in China. This multi-stage tandem system for long-distance calls became a thing of the past, and local telephone networks could communicate without going through the next tandem center.

However, the area code format of that year was retained. Later, the C4 network merged, and the four-digit area code was gone. In this way, the three-digit area code with the second even number will obtain the number resources, ensuring that each municipal administrative unit has at least one three-digit area code. Except for Taiwan Province Province, all localities have used the original spare number resources to fill the vacancy of number resources.

Therefore, the numbers after 63x appear in the area codes of Shandong, Guangdong and Yunnan, and the remaining 898, 899 and 890 in the Tibet area code become Hainan area codes. By May of 20001year, Hainan Province had merged with C3 network, leaving only 898 companies. Due to the special long-distance dialing method of GSM mobile phone, the area code of Beijing has to be changed to 10.
