The credit card limit is increased at the bank’s discretion. However, you can boost your chances of increasing the limit by paying bills before/on time and maintaining a low credit utilization ratio. Moreover, you can also request an increase from the bank if your income has increased.

There isn’t necessarily a certain number of credit cards a person can have. However, having multiple credit cards can be beneficial for your credit score if your credit utilization, spending, and payment habits are in the green.
