What's the area code of China?

International calls always start with "00", which is an international prefix. It is the same to make international calls to any country.

The number after "00" is the international long-distance code of each country.

So when you call China from abroad, it starts with 0086, then the area codes of provinces and municipalities directly under the Central Government (without 0), and then the called number.

For example, if you call from the United States to Beijing, it will broadcast: 0086- 10-8888888, and if you call Changsha, it will broadcast 0086+73 1+888888.

Area code refers to the telephone area code commonly used in the administrative areas of major cities in the world, which is mainly used for domestic and international long-distance telephone access. For example, the international area code of Chinese mainland is 86, while the area code of Chengdu is 28. When using domestic long distance calls, dial 0 before the area code.

It is worth mentioning that people often confuse concepts and mistakenly think that there is a 0 in front of the area code itself. In other words, because 0 is the only long-distance access code in China, it is often used side by side with the following area code, so it has become a habit.

In fact, when calling back to a domestic city from abroad, the local international long-distance telephone access code is added after the China country number 86, and there is no 0 in front of the city area code. For example, the area code of Chengdu should be 28, not 028.

The first level is the capital Beijing, where the National Convergence Center and major international interface bureaus are located. The one-digit area code is 1 (later changed to 10).

At the second level, two-digit area codes are used for municipalities and regional centers. At that time, the three municipalities directly under the Central Government used 2 1 and 22 area codes for Shanghai and Tianjin respectively, and only Beijing used 1 (later changed to 10). The central cities in Northeast China, East China, South China, Central China, Southwest China and Northwest China, Shenyang, Nanjing, Guangzhou, Wuhan, Chengdu and Xi 'an use area codes 24, 25, 20, 27, 28 and 29. 26 is the area code reserved for the regional exchange center in Taiwan Province Province, which can also be understood as reserved for Taibei. Because Taiwan Province Province ranks in East China in the administrative division sequence, the area code of Nanjing, the regional exchange center in East China, is the last one.

The third level is the provincial exchange center and the regional exchange center, using three-digit area code, with the first digit corresponding to the last digit of the two-digit area code of the city where the regional exchange center is located (except North China and South China), and the second digit of the area code is five odd numbers of 1, 3, 5, 7 and 9. Provincial exchange centers (usually the capitals of provincial capitals and autonomous regions) have a mantissa of 1, except for provinces that also have regional exchange centers. In this way, the three-digit area code prefixed with 6 is also reserved for Taiwan Province Province because 26 is reserved.

The fourth level is the county exchange center, which uses a four-digit area code. The first digit is the same as the first digit of the three-digit area code of the trading center in the corresponding region, and the second digit uses five even numbers of 2, 4, 6, 8 and 0.
