What needs to be known is that if the same bank has multiple credit cards, the credit lines of these credit cards are shared, and the credit lines of credit cards with high credit lines are shared. You can increase the credit card limit in the following ways:

1, credit card spending is frequent, it must be frequent, the amount is not necessarily large, but it must be frequent, indicating that you have been spending with this credit card.

2. If you use a credit card, you should repay it on time to ensure a good credit record. If the credit record is not good, it is impossible to increase the limit.

3. It is best to submit financial proof that will help increase the quota, such as real estate license.

4. After using the card for half a year, take the initiative to call customer service and transfer to manual customer service to apply for increasing the quota.
