The fixed credit limit of Shanghai Pudong Development Bank's credit card is approved by the bank according to your personal data and the supporting documents provided when you apply for a credit card. If the credit card limit is insufficient after successful application, you can apply for increasing the fixed credit limit in the following ways:

1. Add financial documents. Banks will evaluate the credit limit of credit card holders when approving. Income level and asset status are important factors. Generally speaking, the higher your income, the higher your credit limit. Therefore, if the economic situation improves, or if you do not provide enough supporting documents when applying for a credit card, you can supplement the proof.

2. Repeated credit card consumption. Credit cards can be used in many places in life, for example, shopping in supermarkets, shopping online, and buying electrical appliances and computers from shopping malls. Try to swipe your card where you can, which shows that your spending power is very strong, and the bank will naturally know that you have the need to increase the credit card limit.

3. Repay on time after consumption. After spending by credit card, you must repay in time every month, and don't miss the last repayment date. On the one hand, this is a good performance of the cardholder's credit, on the other hand, it can also prove the cardholder's repayment ability.
