The limit of China Construction Bank's platinum credit card is generally more than 50,000 yuan. The specific limit will be determined by CCB based on the information submitted by the user.

If the user has applied for a CCB platinum card, he can check his credit limit through the following methods:

1. Mobile banking inquiry. Log in to CCB Mobile Banking and click "Credit Card" to view the credit limit information;

2. WeChat inquiry. Follow the "China Construction Bank" official account and bind your credit card to view card limit and other information.

If the user feels that the credit card limit is low, after using it for a period of time, enter the "China Construction Bank" official account, click "Credit Card" - "Bill/Repayment/Limit Management", and then select Limit Management to adjust your credit card limit.
