Where did the text message starting with 00852 come from?

Chinese mainland area code 86, Beijing area code 0 10, Guangzhou area code 020, and so on. When using domestic long distance calls, please dial 0 first and then the area code. It is worth mentioning that people easily 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 domestic long-distance access code, it is often used side by side with the following area code, so it is a habit. In fact, when dialing back to domestic cities from abroad, the domestic and international long-distance telephone access code is added after China's country code 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 numbering principle of area code:

The principle of multilevel tandem classification is to set up a main international interface office, which is divided into several areas according to long-distance traffic and administrative divisions, and each area is set up with a tandem center, that is, a primary switching center; Each region is divided into several provinces, and each province has another center, namely the secondary exchange center;

Each province is divided into several regions, with the center in the regional central city, that is, the third-level exchange center, followed by the county center, and the county below each region has a fourth-level exchange center; The five-level switching center is a local exchange end office, which is generally a local exchange end office.

Generally speaking, if you make a long-distance call to Beijing from Mengla County, Xishuangbanna Dai Autonomous Prefecture, Yunnan Province, the signal must be relayed from Mengla County to Xishuangbanna Central Bureau, then to Kunming Central Bureau, and then to Chengdu Central Bureau, the center of southwest China, in order to reach Beijing.

Based on this "multilevel tandem system", the compilation of telephone long-distance area code also embodies the "multilevel" principle, and the arrangement of numbers also reflects a certain correspondence.
