Please ask: Why are the mobile phone numbers in my country all 13****? Is this related to the mobile phone signal frequency? Please explain in detail.

Everyone knows that China Telecom, Mobile and Post were not separated before, and post and telecommunications resources were uniformly dispatched by the Ministry of Posts and Telecommunications (now the Ministry of Information Industry).

When allocating number segments, we made some detailed planning, which is roughly as follows:

Telecom service numbers starting with 10, such as 103 international semi-automatic registration, 108 international collect call , 1000 Telecom Service Center, 1001 China Unicom Service Center, etc.

Special service numbers starting with 11 are assigned, such as 110 police, 111 telecommunications internal testing, 112 repair, 113, 115 domestic manual long-distance registration, 114 directory inquiry, 116 domestic manual long-distance inquiry, 117 time, 119 fire alarm, etc.

Special numbers starting with 12 are given to civilians, such as 120 (hospital), 121 (weather forecast), 122 traffic accident warning, 126, 127, 128, 129 paging stations (BP machine era).

So when assigned to mobile phone users, the number segment starts with 13. Later, numbers 130~133 were assigned to China Unicom, and numbers 134~139 were assigned to China Mobile.

Other special segment numbers are:

14, 15, unallocated, spare

16, voice type, such as 160 China Telecom Workers Information Service Access Input code, 166 voice mailbox service, 167 Jitong computer Internet service access code, 168 voice service, China Telecom public multimedia network access code, etc.

17, long-distance telephone service, such as 170 domestic long-distance fully automatic call bill Inquiry desk, 173 domestic direct long-distance semi-automatic registration desk, 176 domestic long-distance semi-automatic inquiry desk, 177 domestic long-distance semi-automatic monitor desk, 179 IP voice service access code, etc.

18, some service desks, such as 180 Postal Service Services, 184 postal code inquiry access code, 185 State Post Bureau telephone information service access code, 186 mobile service center, 188 fixed telephone payment desk, 189 China Telecom business acceptance special service desk, etc.

19, paging access, 191 China Unicom radio manual paging access code, 192 China Unicom radio automatic paging access code, etc.

20, 30, phone card service

In addition, the number segments starting with 8 and 9 are also used as telecommunications and civil service numbers

The above numbers are all allocated. There are too many contents to list in detail. Some numbers have been upgraded, such as Telecom service desk, weather forecast, postal service desk, etc.

Currently, mobile phone numbers starting with 159 have appeared in Guangdong, Chongqing, Beijing, Shanghai and other places, and it is believed that they will appear in other regions soon.
