Hello, there is no special restriction in theory. You can apply for a credit card at any bank. Some banks may have restrictions on the number of credit cards under an ID card, usually 3-5, while others have no restrictions. There are many people who handle more than ten credit cards.

However, some banks will access your credit information at the People's Bank of China when approving credit cards. If you see that you already have more credit cards, you can consider giving you a slightly lower limit or even not giving it to you for the time being.

But the credit limit set by each bank is bound to your ID card. For example, if you have five ICBC credit cards, each with a limit of 10000, don't think that you can draw out 50,000, but five credit cards, totaling 10000.

Therefore, if you feel that the credit limit is not enough, it is recommended to apply for a credit card from another bank. At present, many banks have the measure of "using cards to handle cards". To put it simply, this bank will give you as much credit as other banks. Need to prepare materials, ID card plus a copy of your credit card, plus a credit card bill at most.

If you have any other questions, I suggest you call the customer service staff of the bank, hoping to help you.
