Why do Chinese mobile phone numbers start with 13?

This question seems to have been recommended the other day.

In the past, telecommunications, mobile and postal services were not separated, and post and telecommunications resources were uniformly dispatched by the Ministry of Posts and Telecommunications (now the Ministry of Information Industry).

When assigning the number segment, some careful planning was done, and it was generally like this:

At the beginning of 10, telecommunication service numbers, such as 103 international semi-automatic**, 108 international counterparty paying**, 1000 telecommunication service center, 1001 Unicom service center, etc.

At the beginning of 11, give special service numbers, such as 110 bandit police, 111 telecom internal test, 112 repair domestic manual long-distance **, 114 number check, 116 domestic manual long-distance inquiry, 117 time signal, 119 fire alarm, etc., 12 start, give civilian special numbers, such as 120 (hospital), 121 (weather forecast), 122 traffic accident alarm paging station (BP machine era).

Therefore, when assigned to mobile phone users, the number segment starts with 13. Subsequently, 130,133 were assigned for Unicom and 134,139 for Mobile.

Other special segment numbers are:

16. Voice messaging, such as 160 China Telecom worker information service access code, 166 voicemail service, 167 Jitong computer Internet service access code, 168 voice messaging service, China Telecom public multi-network access code, etc.

17. Long-distance ** service, such as 170 domestic long-distance automatic phone bill inquiry desk, 173 domestic vertical system long-distance semi-automatic ** platform, 176 domestic long-distance semi-automatic inquiry desk, 177 domestic long-distance semi-automatic squad leader station, 179ip voice service access code, etc.

18. Some service desks, such as 180 postal services, 184 postal code query access code, 185 State Post Bureau ** information service access code, 186 mobile service center, 188 fixed ** payment desk, 189 China Telecom business acceptance special service desk, etc.

19, paging access, 191 Unicom radio manual paging access code, 192 Unicom radio automatic paging access code and so on.

20, 30, ** card service.

In addition, the opening part of the number segment is also used as telecommunications and civil service numbers.

Some of the numbers have been upgraded, such as telecommunication desks, weather forecasts, postal service desks, etc.

As for the number of the 150-159 segment today, it is because the previous 130-139 segment can no longer meet the rapidly rising demand for mobile phone use in China, and a new number segment is specially opened.

Fixed ** numbers will use the prefix 2---9. And the 0 prefix is the long-distance area code. In order to distinguish between mobile and fixed** numbers, you can only choose the prefix 1 for moving**.

There are many special numbers at the prefix 1. For example, etc. In fact, they are all special numbers.

all have a special role. So the phone can't use the prefix 11. Prevent mistakes and troubles caused by misdialing other special numbers or because the first 3 digits are the same as a special number.

Since the prefix 11 is not available. What about 12. It is also unavailable. We all know that there are 120. There are also 12315 and so on are also special numbers. So 120 is also not available.

That's 13. Just right. What else to look for. 14? Chinese are very taboo about color heads. How can you use 14As for those that are the same as above. Needless to say.

Perhaps this is not the main reason why Mobile Telecom chose 13. But I think my speculation is justified.

The question is that there are many things, and everything starts the same, don't you have to hit **?
