Campus cards with ID cards often have strange numbers to call and receive many insurance messages. Will my credibility be in question?

This has no effect on your reputation. Because this number has been used by others before. If you are in arrears for three months, the system will take the initiative to recover this number. Then you used this number. Because the old number was leaked. There will be a lot of harassing calls coming in. You can go to the business hall to handle an anti-high frequency harassment activity. It is specially used to intercept such harassing numbers or text messages.
