To apply for increasing the permanent credit card limit, the following conditions are generally required. If your credit card is used normally but refused to apply for withdrawal, you can find out the reason by comparing the following situations:

1. The larger the quantity, the better, and the total consumption for half a year is at least 60% of the quota;

2. Consume as much as possible, with an average of more than 20 transactions per month 10, and it is easier to withdraw cash;

There are many types of consumer businesses, such as shopping malls, supermarkets, gas stations, restaurants, hotels, tourist and entertainment places.

4. The less wholesale and large-scale consumption such as buying houses and cars, the easier it is to raise the amount;

5. The less online shopping, Alipay transactions and cash withdrawals, the easier it is to approve the application for increasing the quota;

6. The type of merchants who swipe their cards cannot always be similar to the business scope of the company;

7. Provide more financial certificates such as car books, household registration books or bank wealth management products;

8. There is no overdue bad record.
