The limit is approved by the bank. If it is not enough, you can apply for increasing the limit.

There are the following ways to increase the bank credit card limit:

Provide sufficient financial proof when applying for the card. When applying for a credit card, provide as many financial proofs as possible, such as proof of income, proof of bank deposit, proof of real estate, proof of vehicle production, etc. The bank will evaluate the assets of the cardholder according to these proofs. If the cardholder has a deposit in China Construction Bank or is a civil servant, it will also help the cardholder to obtain a good credit, and it will also help to approve a higher credit limit;

spend as much as possible by credit card. The bank will make a comprehensive evaluation based on the customer's past card use. It is suggested that cardholders can diversify their consumption types, such as household appliances consumption, catering consumption, supermarket shopping, etc., and spend as much as possible in physical stores. The bank credit card center will adjust the quota according to the cardholder's utilization rate of credit cards and repayment records;

ensure a good repayment record. After using the bank credit card to spend money, you should ensure that you repay on time before the repayment date every month. Once it is overdue, it will not only pay a high late fee, but also produce a bad credit record, which will affect future credit card applications. If you can't repay in time in case of emergency, you can call the bank's customer service hotline and apply for deferred repayment;

apply to increase the temporary quota. Bank credit card holders can apply for the initiative to increase the temporary limit, and the bank will comprehensively evaluate the range of the limit that the cardholder can increase according to the cardholder's usual consumption and repayment. If the temporary quota is often raised, banks will think that there is a strong demand for credit cards, and it is not difficult to raise the fixed quota. The temporary limit needs to be paid off in one lump sum. Please be careful not to generate late fees.

these are the basic methods for bank credit card application and withdrawal services.
