Does Discover pull a credit report when you request a line increase? What about Citibank Aadvantage. I want to get some lines raised but do not want a credit pull. I have Amex Starwood and I know they pull a report even if you have been a good customer. I am trying to increase my score by letting utilization drop a little. I went to 25% utilization from 10% and lost 33 points with Equifax. One thing is for sure Equifax scores moves the most. FICO moves much less.
