Someone who has your name, Social Security number and a few other details can sometimes open a credit card or loan in your name without you knowing. A credit freeze is one tool built to block that. It is free, it is available to anyone in the United States, and it does not require you to pay a monthly fee. It also has limits, so it helps to know what it does and what it leaves alone before you start.
What a credit freeze does
A credit freeze, also called a security freeze, stops prospective creditors from getting into your credit file. A credit file is the record of your borrowing and payment history that lenders use to decide whether to approve you. Many lenders check that file before they approve an application. When the file is frozen, the lender usually cannot see it, so the application generally stalls. That is true whether the application came from a thief or from you.
The freeze does not lock out everyone, though. Creditors where you already have an account can still see your file. Certain government entities, such as child support agencies, can also access it. So can companies you have hired to monitor your file. Knowing this helps you set realistic expectations. A freeze targets new accounts. It does not stop a bill collector or your current card issuer from looking at your history.
You can still check your own credit reports while a freeze is in place. Asking for your own file is not blocked. That matters because reviewing your reports is one of the best ways to spot an account you never opened. A freeze does not get in the way of that check.
How to place, lift and unfreeze
The part that trips people up is that a freeze is not one switch. You place it separately with each of the three nationwide credit reporting companies: Equifax, Experian and TransUnion. If you contact only one, the other two files stay open, and a thief could still apply through them. Plan to make three requests, and keep a note of the date you made each one.
You can request a freeze online, by phone or by mail. The timing differs by method. According to USAGov, requests made online or by phone must be honored within one business day, and requests made by mail must be honored within three business days. Check each bureau's current instructions before you start, since the exact steps on their websites or phone menus can change.
Lifting a freeze is the other half of the job. You will need to lift it when you apply for a loan, card or other credit that requires the lender to see your file. A lift can be permanent or temporary. Online and phone lift requests must be completed within one hour, according to the federal guidance summarized by USAGov. Mailed requests take up to three business days. If you expect to apply for credit soon, plan ahead so you are not waiting on a mailed letter when a lender needs an answer.
Placing, lifting and unfreezing are free at each of the three bureaus. These requests go to the credit reporting company, not to your creditors. That is an easy detail to miss, and it is worth remembering if a lender asks you to do something with the freeze on their end.
Freeze versus fraud alert and credit lock
A credit freeze is not the only option, and the Federal Trade Commission presents it alongside the fraud alert as a separate tool. A freeze is generally the stronger block on new accounts. A fraud alert works differently. It asks businesses to take extra steps to verify identity before extending credit, and it is a separate choice you can compare before deciding. The FTC's comparison page is a good place to read the tradeoffs in plain language.
You may also see paid products called credit locks. These are offered by some credit reporting companies for a fee. The Consumer Financial Protection Bureau says credit locks are no more effective than security freezes, which are free and which federal law gives you a right to request. A paid lock is not required to get comparable protection. If you are weighing one, ask what it does that a free freeze does not, and whether the cost is worth it for your situation.
One more wrinkle: the federal law that requires free security freezes does not cover every kind of report request. Requests for your report for employment, tenant-screening or insurance purposes fall outside that free-freeze requirement, according to the CFPB. Before you assume a freeze applies to those requests, check how they are handled. Reading the CFPB's explainer is a good starting point.
Questions to ask and warning signs
Before you place a freeze, run through a short checklist. Have you contacted all three nationwide bureaus? Each freeze is separate, so one request is not enough. Do you know how long a lift will take using the method you plan to use? Are you choosing a free official freeze, or a paid credit lock that a company has bundled with other services you must pay for? Paid offers that push you to act right away are a red flag.
Be careful with unexpected calls, emails or texts that urge you to act immediately on identity or credit matters. The FTC warns about impersonation and scam contacts in general. A safer approach is to start the freeze yourself through the bureau's official contact channels, not through a link or phone number someone else sends you. If you are unsure whether a message is real, hang up and look up the bureau's number on your own.
Some questions are not answered by the government sources. They do not say how a freeze affects every credit-based decision, or how long a freeze lasts when no end date is set. They also do not explain how to verify identity for a mailed request, or how freezes work for a child's or a protected person's file. Those are worth raising directly with the credit reporting company, or with the CFPB and FTC. For your own situation, a qualified professional can also help you decide what fits.
A freeze can help if you suspect someone has stolen your personal information. It is one step, not the whole response. The FTC's consumer alert on credit freezes and identity thieves walks through the basics. Read the official guidance from the Consumer Financial Protection Bureau, the USAGov credit freeze guide, and the FTC's explainer on credit freezes and fraud alerts before you decide.
