Hello, this is the customer service of China Bank. The phone number you provided is from Lanzhou Construction Bank. No problem. Most students don't give it to you. Since the bank took the initiative to ask you to do it, it means that you meet their credit card issuance standards. As long as the application from CCB official website is correct, it will not be used. But are you sure that you entered CCB official website? If you can, just wait for the credit call from the bank. After the phone call, you can wait for the card. Good luck.
