1. Can the credit card phone number not be my own?
It doesn't work in principle. To apply for a credit card, you have to use the applicant's personal information, such as my identity certificate, my work certificate, income certificate and so on. And you may need my signature, so the mobile phone number must also be my real name registration system.
Some people may use the mobile phone number of someone else's identity information office, thinking that it is for their own use anyway, even if it is not their own number. This may be considered by banks as providing false information and refusing to lend. After all, the mobile phone number of the applicant's real-name registration system can now be found in the credit report.
Of course, the bank may also default to the number currently used by the applicant as its own number, but for cardholders, it is very risky to use the phone number of other people's identity information. First, others can report the loss of their phone numbers and reissue their cards at will, which may reveal credit card information; Second, the mobile phone has lost a calling card that is not my identity information office, so it is more troublesome to replace the card.
Second, matters needing attention
It is safest to use your own credit card phone, but everyone should also pay attention to the safety of using the card.
If you have a credit card bound to WeChat or Alipay, you'd better install interception software on your mobile phone to filter out spam messages. Don't click on the links on all kinds of short messages received by your mobile phone easily, and don't browse some websites with security risks on your mobile phone to avoid the theft of mobile phone information.
