There are two kinds of credit card limit that can be increased, one is fixed limit and the other is temporary limit. You can call to apply for adjusting these two limits. The fixed amount requires the cardholder to hold the card for about half a year. Call the 24-hour customer service hotline of the bank credit card to apply for adjusting the credit card application amount. According to your card usage and repayment records in the past six months, the bank will inform the customer of the audit results within one week. If the cardholder can provide some assets proof materials when submitting the application, he can get a higher credit limit.

Temporary credit limit, you can apply to the bank in advance to temporarily increase the credit limit, and the bank will adjust it for you according to your credit status and card usage. Generally speaking, the temporary credit line is valid for up to 3 months, and your credit line will be automatically restored to the original one after expiration.
