First, two credit cards of a bank share the same credit limit, and the credit limit will not be accumulated when the number of cards is increased. If there are more than one credit card, please log in to online banking/mobile banking to inquire about credit card transactions, and all the bills inquired are card transactions. You can judge which card is the transaction by the "last four digits of the card number" in the credit card bill details.

Second, credit card limit sharing related content

1. Line sharing means that the credit cards of the same bank share the same line, and the sharing line is subject to the maximum line of your credit card. For example, if you have a credit card with a line of 1000 and a credit card with a line of 30,000, the sharing line is 30,000 yuan, which means that when the card with a line of 1000 spends 5,000 yuan, the card with a line of 30,000 can only use the remaining 25,000 yuan.

2. A credit card has a credit line, which is divided into a fixed line and a temporary line. The credit card fixed limit refers to the maximum credit limit that the card issuer can give to the cardholder within the prescribed time limit according to the credit status of the cardholder. The usual credit card limit is fixed. Temporary credit card line refers to the temporary credit line that the bank temporarily increases on the basis of permanent credit line to meet the temporary needs of customers.

3. Ensure that the credit card can be repaid in full and on time. This is very important for credit card holders who want to raise the limit. If you can't repay in full and on time, there will be a bad record of credit card repayment, which will not only affect the cardholder's personal credit information, but also greatly extend the time for credit card to increase the credit limit.

4. The rule that credit card lines are shared in the same bank is to prevent the risk of excessive credit granting by cardholders and facilitate the risk management of banks. Therefore, for cardholders, it is of little significance that multiple credit cards do not increase the limit. If you want to increase the total credit line, you can apply for multiple credit cards from different banks. In addition, except for a few banks such as China Merchants Bank, which share one account with multiple credit cards and issue one bill, most banks use multiple credit cards as independent accounts and issue bills separately, which is troublesome to manage.
