<prompt> Human: Hey guys, 20 year old here. I have one credit card and its been about a year now since I opened it. I started at a 300 credit line which they bumped up to 600 around Christmas. Today I woke up to see my credit line has been increased to 2,000. I dont use it very much , have never missed a payment and only utilize about 30 of the credit. I did not request a credit line increase.Is a jump from 600 to 2,000 intentional or was this an error?  <response>: Credit card companies will frequently increase your limit if youve been responsible with it.Nothing to be alarmed at. In fact, if you maintain your current spending, your credit rating will go up as you will utilize less of your total limit.
