If you want to increase the quota, you need to submit an application for upgrading the construction bank card. How can I submit the application? If the cardholder wants to improve the credit rating for a long time, he/she needs to call the 24-hour customer hotline of China Construction Bank at 4008200588 to apply for credit card limit adjustment after six months.

Previously, according to the repayment records of the past six months, the cardholder would inform the customer of the audit results within one week. If the application is submitted, the cardholder can provide some assets proof materials, thus obtaining higher credit.
