China Mobile Science: Why your phone number is 11?

via:快科技     time:2018/3/4 15:30:54     readed:309

First, China's mobile phone number is divided into three sections, each section has a different meaning, the first three is the network identification number, 4 to 7 is the area code, 8 to 11 is the user's number (random allocation).

Therefore, the correct reading of your phone number is: 1XX-XXXX-XXXX.

China Mobile said that this configuration can maximize the use of number resources, will not result in waste, but also ensure flexible allocation.

Second, China's previous cell phone number is indeed 10 digits, but due to the growing number of users, the number of resources can not be met, so rose to 11.

In theory, there are 100 billion 11-digit numbers, "1" for public use, and 10 billion for 10-digit numbers. Each and every one of our country can also allocate 78 people.
