Why did my discover credit line increase

Discover may automatically increase your credit limit depending on your account history and creditworthiness. If you consistently make on-time payments on your Discover card account, for example, you might be more likely to receive an automatic credit limit increase than someone who regularly misses payments.

You've used your existing credit line responsibly You pay every credit card bill on time. As a reward, the credit card issuer may automatically grant you a higher credit limit, or invite you to request one. It could be just a small bump, or it may be as much as 30%.

You can contact your credit card issuer and request an increase. You may have to provide information like your updated income and housing information before a decision is provided. The credit card issuer may choose to increase your credit limit without you requesting an increase.

Increasing your credit limit lowers your credit utilization ratio. If your spending habits stay the same, you could boost your credit score if you continue to make your monthly payments on time. But if you drastically increase your spending with your increased credit limit, you could hurt your credit score.
