If you get a copy of your own credit report, that will not hurt or help your score. The bureaus treat a “self-disclosure” as a nonevent. Obviously, you’re not checking your report to see whether you should lend yourself money. So it’s not an official inquiry. You could check your report every week and it wouldn’t hurt your score one bit.
There are other inquiries that also don’t hurt you. One is an “account review” by current creditors. Most creditors pull your file at least a couple of times a year to make sure you’re still the credit risk they thought you were the last time they checked. Another that doesn’t count: “promotional” inquiries. These are made by companies that have purchased your basic information without your knowledge and want to consider soliciting you for some kind of credit offer or business transaction.
