The application for Su Kang code shows that the ID number already exists, which means that other mobile phone numbers may have been authenticated by the ID number. Applying for a Su Kang code with a new mobile phone number will show that the ID number already exists, so when some mobile phone numbers are not used, you must release the identity authentication information in time.
Otherwise, there will be some trouble when you use your ID card to authenticate something later, which is caused by things that have not been done before. With the arrival of the epidemic, health code has become the basic factor to judge whether a person is in danger. Many occasions, including going to work, need health codes, and Jiangsu is no exception.
Due to the convenience of software, there are many channels to apply for Su Kang code. For example, Alipay and Ninggui APP can fill in relevant information to apply for Su Kang code.
The reason for this situation is probably that the previous mobile phone number did not cancel the identity authentication in time. At this time, when applying for Su Kang code with the current mobile phone number, it will show that the identity information has been occupied. Just pass the mobile phone verification on the APP and re-use the ID card for real-name authentication.
However, we should be cautious about identity information, and unused mobile phone numbers must be released in time, so that there will be no problems in using relevant information in the future.
