A soft credit check is a review of your credit report and credit score that does not affect or lower your credit score.
Unlike hard credit check or hard inquiry that can lower your credit score, the soft credit check does not lower or affect your credit score.
Soft credit checks are done when you or a company looks at your credit report for reasons, other than applying for new credit.
Examples of when a soft credit check can occur are when you check your own credit, when you get pre-approved for an offer or when an employer does a background check on you.
Soft credit checks are also visible to you on your credit report, although the soft credit checks are not seen by lenders and don't cause your credit score to lower.
Even an existing creditor reviewing your account for monitoring and maintenance purposes an insurance company that is checking your credit to determine your insurance premium are also examples of a soft credit check.
So there's no need to worry about a soft credit check as soft credit checks won't affect your credit score or credit and a soft credit check won't affect your ability to get credit or loans in the future.
You also can't fail a soft credit check and it won't result in a lender's decision.
