Real name reason

From September 1 2005, all kinds of entity marketing channels of telecom enterprises will be fully equipped with second-generation ID card identification equipment. When going through the network access procedures for users, we must use the second-generation ID card identification equipment to verify the user's own resident ID card, and automatically enter the user identity information through the system. The original intention of implementing the real-name registration system is to curb the spread of bad information, prevent and crack down on all kinds of telephone fraud activities, and solve the problem that it is difficult for relevant departments to obtain evidence and investigate and deal with it.

In order to comprehensively promote the re-registration of unnamed old users, telecom enterprises should require them to re-register unnamed old users who entered the network before September 20 13, and replace their mobile phone cards according to law to ensure that the real-name registration rate of all telephone users in the enterprise reaches 90% before September 20 15 12 3 1 year. ?

The three major operators, China Telecom, China Unicom and China Mobile, said that their non-real-name mobile phone numbers may be shut down. The real-name registration system must be present with my ID card when making supplementary registration.
