If it is an individual, consignment is generally not allowed. If you must check: refer to the following methods. In the case of only knowing the mobile phone number, there are two ways to find out the personal information of the owner:
First, people who work in China Unicom have intranet systems. If they have the right, they can query by entering their mobile phone number, and they can also see detailed information such as call details, but they will not be easily provided to the outside world, and there must be legitimate and justified reasons;
The second is that the public security organ can inquire, but it must have the certificate of the relevant authorization of the public security organ and affix the official seal, otherwise Unicom will refuse to accept it.
If the mobile phone number is a real-name registration system, the police station can check the identity of the registrant. Under normal circumstances, it is personal information, and you can't query it at will. This is personal privacy, unless the public security department needs to handle a case, it has the right to investigate. Under normal circumstances, it is not allowed, because the identity card system of China citizens is directly under the jurisdiction of the Public Security Bureau. Mobile phone number is the system management of the three major operators. If you have ID information, you can go to the business hall of the corresponding operator to inquire, but this service is basically not provided in the current business hall. Unless there is a certificate from the public security bureau.
You can check the citizen's ID number: citizen's basic information: 1, name 2, gender. 3. age. 4. Nationality. 5. Household registration. 6. address Relevant information: entry and exit information, illegal and criminal information, drug abuse information, fugitive information, motor vehicle information, family members and other information.
