How to Stop Credit Inquiries: Freezes, Alerts, and Disputes

To stop credit inquiries, you use three tools that each address a different kind of inquiry: a security freeze at each credit bureau blocks lenders from pulling your file for new applications, an opt-out at OptOutPrescreen.com ends the soft inquiries behind pre-screened credit and insurance offers, and a formal dispute removes unauthorized hard inquiries already on your report. Federal law makes all three free, and you can use them together.

Which Inquiries You Can Actually Stop

A hard inquiry appears when a lender pulls your report to decide on an application, such as a mortgage, auto loan, or credit card. Each one typically lowers a FICO score by fewer than five points, the scoring effect fades after about 12 months, and the inquiry drops off entirely after two years. A soft inquiry happens when someone checks your credit for a non-lending reason, such as a background check, an insurance quote, or a pre-screened marketing offer. Soft inquiries do not affect your score and are not visible to lenders reviewing your file.

That split matters, because the tool you need depends on the kind of inquiry you want to stop. A freeze prevents future hard inquiries. An opt-out shuts down the marketing soft inquiries behind junk-mail credit offers. A dispute removes an unauthorized hard inquiry that has already posted. Before you use any of them, pull your reports at AnnualCreditReport.com, the only federally authorized site for free credit reports; all three major bureaus now provide free weekly reports there on a permanent basis.¹ Checking your own file counts as a soft inquiry and has no effect on your score. Note the company name and date of anything you do not recognize; you will need both if you dispute it.

Stop Pre-Screened Credit Offers

Pre-screened offers are the credit card and insurance solicitations that arrive in the mail because a lender asked a bureau to identify consumers who meet certain criteria. They generate soft inquiries: harmless to your score, but they mean companies are accessing your file for marketing.²

You have two ways to stop them:

A five-year opt-out. Go to OptOutPrescreen.com or call 1-888-5-OPT-OUT (1-888-567-8688). The electronic or phone request takes effect immediately and lasts five years.³
A permanent opt-out. Start at the same site or number, then print the Permanent Opt-Out Election form, sign it, and mail it to the address shown. The mailed form completes the lifetime removal.³

The five-year option does not send a reminder before it expires. You can return to the site anytime to renew, upgrade to permanent, or opt back in.

Block Future Unauthorized Hard Inquiries With a Freeze

A security freeze locks your credit file so no new creditor can pull your report. Because most lenders will not extend credit without a report, a freeze effectively prevents anyone, including identity thieves, from opening accounts in your name. Federal law requires each consumer reporting agency to place and remove freezes at no cost.⁴

You have to freeze your file at each bureau separately. A freeze at one does not carry to the others.

Equifax: use the Equifax security freeze page online or call 888-378-4329.
Experian: log into your Experian account and select “Add a Freeze,” or call 888-397-3742.
TransUnion: use TransUnion’s Credit Freeze portal online or call 800-916-8800.

Each bureau also accepts freeze requests by mail. Online and phone requests must be placed within one business day; mailed requests within three business days.⁴

Beyond the big three, Innovis is a smaller consumer reporting agency that some lenders use. You can place a free freeze at innovis.com or by calling 800-540-2505. Fewer creditors check Innovis, but freezing there closes one more avenue for identity theft.

Thawing the Freeze When You Need Credit

A freeze stays in place until you remove it, so you will need to thaw it whenever you legitimately apply for a loan, credit card, apartment, or anything else that requires a credit check. You can request either a temporary lift, where you set a date range and the freeze snaps back at the end of it, or a permanent removal that keeps your file open until you refreeze.

Online and phone lift requests must be processed within one hour; mailed requests within three business days.⁴ If the lender tells you which bureau they check, you only need to lift the freeze at that one.

Remove Hard Inquiries Already on Your Report

If your report shows a hard inquiry from a company you never applied to, you can dispute it. Federal law requires the bureau to investigate any challenged item and to remove it if the inquiry cannot be verified as legitimate.⁵

What Qualifies as Unauthorized

A company can only pull your report if it has a “permissible purpose.” The common ones are reviewing your credit application, employment screening with your written consent, insurance underwriting, and account review by an existing creditor.⁶ An inquiry outside those categories, such as a company you have no relationship with pulling your report without your knowledge, lacks permissible purpose and can be disputed.

How to File

You can dispute online through each bureau’s dispute center, but a written dispute sent by certified mail with return receipt gives you a paper trail. Include your full name, Social Security number, date of birth, and current address; the exact company name and date of the inquiry you are challenging; a clear statement that you did not authorize the inquiry and that it lacks permissible purpose; and copies (not originals) of your government-issued ID plus anything else showing you did not apply for credit with that company.

The bureau generally has 30 days from receiving the dispute to complete its investigation. If the inquiring company cannot verify permissible purpose, the inquiry must be removed. The bureau then sends you a written notice of the outcome and an updated copy of your report.⁵

Only dispute inquiries that genuinely appeared without your permission. If you applied for a credit card and a hard inquiry resulted, the inquiry is legitimate and will stay. Disputing valid inquiries accomplishes nothing; the bureau confirms the record and the inquiry remains. Legitimate hard inquiries drop off your report automatically after two years, and their scoring effect fades well before that.

Fraud Alerts as a Lighter Alternative

A fraud alert does not block access to your file the way a freeze does. It tells any lender who pulls your report to take extra steps to verify your identity before extending credit. That can be useful if you suspect your information was exposed but still want to apply for credit without thawing a freeze each time. A lender can technically still extend credit without verifying, though doing so exposes them to liability, so protection is weaker than a freeze.

Three types are available:

Initial fraud alert, which lasts at least one year. You contact any single bureau, and that bureau must notify the other two.⁴
Extended fraud alert, which lasts seven years and requires an identity theft report, typically a police report or FTC identity theft report.⁴
Active duty military alert, which lasts at least 12 months for service members on active duty and automatically excludes you from pre-screened marketing lists for two years.⁴

Freezing a Child’s Credit File

Children are frequent identity theft targets because their credit files are usually blank and fraud can go undetected for years. Federal law lets a parent, legal guardian, or child welfare representative request a security freeze for anyone under 16. If the child has no existing file, the bureau must create one solely to freeze it; that file cannot be used for credit decisions.⁷

You will generally need proof of your authority (such as a birth certificate showing you as the parent), proof of the child’s identity, and your own ID. Foster care representatives must supply documentation from the child welfare or probation agency certifying the child is in their care. The freeze is free at all three major bureaus.⁷

Picking the Right Combination

Each tool addresses a different problem, and you can stack them.

A security freeze is the best long-term protection when you are not actively applying for credit. You will thaw it when you need to apply.
Opting out of pre-screened offers cuts marketing soft inquiries and the junk mail they generate. It does not block hard inquiries from legitimate applications.²
A fraud alert works as a shorter-term measure after a breach or suspected exposure. It is easier to manage than a freeze, since one bureau notifies the others, but the protection is weaker.
A dispute is reactive: it removes unauthorized hard inquiries already showing on your report rather than preventing new ones.

For the strongest coverage, combine a freeze at all three major bureaus (plus Innovis) with a permanent opt-out from pre-screened offers. The freeze blocks unauthorized hard inquiries; the opt-out ends the marketing soft inquiries behind unsolicited credit offers. If something unauthorized has already posted, use the dispute process to get it removed.
