Soft inquiries do not affect your score. They have no negative impact on your credit at all.
They're used for two reasons: 1) by companies that you already have an account with, and 2) by self-initiated services to check your credit report such as an online score tracker.
Get Your Inquiries Removed Professionally
In some cases, we recommend speaking with a Credit Repair professional to analyze your credit report. It's so much less stress, hassle, and time to let professionals identify the reasons for your score drop.
If you're looking for a reputable company to increase your credit score, we recommend Credit Glory. Call them on (866-656-9334) or setup a consultation with them. They also happen to have incredible customer service.
