Actually increasing your credit line means your score will go up. It has to be approved by the lender. If they are willing to let you have a bigger credit line, it means they trust that you will pay back your debt. So keep requesting for larger credit lines.

If they reduce your credit line, that means they don't trust you with their money. that will lower your score.

800 score – great
700 score – good
600 score – bad
500 score and below – terrible (subprime)

only by a few points.
everytime anyone pulls your credit it hurts it. but if they approve your credit limit increase it can work out for you in about 6 months if you keep your ratio to 1/3 (ex: limit is $1,000 and you only have $300 charged)

If the lender runs an updated credit inquiry, it will set you back — typically something in the range of 2 to 7 points. If you're conservative in making requests for new credit, the hit is typically of little consequence. However, if you aggressively apply for new credit/request line increases, the cumulative impact on your score can be sizable.

Remember, though, that most lenders will run an inquiry with only one of the 3 primary credit bureaus. So your score isn't impacted across the board. If the line increase is granted, is has the potential to increase your score — something that will impact each of your credit bureau reports, not just one.
