What are the telephone area codes of provinces and cities in China?

The telephone area codes of provinces and cities in China are as follows:

The country code of People's Republic of China (PRC) for international calls: 86 provides the telephone area codes of the governments of provinces, municipalities directly under the Central Government and some big cities.

Area code structure

1. When making a domestic call in Chinese mainland, dial the toll number 0. For example, to make a long-distance call from Shanghai to Beijing, you should dial the long-distance crown code 0, Beijing area code 10 and telephone number. However, when calling Chinese mainland from overseas (including Hongkong and Macau), you don't need to dial the long-distance crown code 0. For example, to make an international direct dial call from the United States to Beijing, China, you should dial the local international crown code 0 1 1, China international area code 86, Beijing area code 10, and the telephone number.

2. In Chinese mainland, if you want to make an international long-distance call (including Hongkong and Macau), you need to add the international crown code "00" first, then add the international area code, destination code and user's telephone number before you can connect.

3. The switch structure in People's Republic of China (PRC) adopts four-level tandem radiation long-distance telephone network.
