1. The People's Bank of China (the head office of all banks) has everyone's credit records. You can find information at the head office when you apply for a card at any bank. When you apply for a card, he will call up the previous card application record as a reference to check your credit status. As for the work unit, you didn't mention your current unit, and the bank should not know about it. I'm confused about this. Did you mention it when you applied for the card, or did you write it before? This problem is not as serious as you think. The reason why the bank wants you to fill in the company's contact information is that you hope to have one more contact information in the future, and also hope that you can check whether your situation is true when you make a credit inquiry. Your practice is likely to affect the application for this card, because the bank may think that your credit is not high. After all, trust is a matter for both sides. You must call the credit card center to modify the company information. It may not affect you. Finally, I will give you a card. In addition, this will not affect the credit records of other banks. No, as mentioned above, it's not that serious. What is serious is that you don't pay back what you owe. 4. For example, the first point. Generally speaking, there is no need to be in such a hurry in this case. Just make a phone call and explain the reason.
