Quick Answer
Credit freeze (also called a security freeze): A free tool — backed by federal law — that restricts who can access your credit report. Because most lenders need to check your report before opening new credit, a freeze makes it much harder for someone to open a fraudulent account in your name.1
Credit lock: A similar-sounding feature offered by credit bureaus or third-party services — usually through an app — that also restricts report access. However, the CFPB is clear: credit locks are no more effective than freezes, and freezes are free and a legal right. A lock is a product feature with its own terms; a freeze is a federal protection.1
Fraud alert: A different tool altogether. Instead of blocking access to your report, a fraud alert tells lenders to take extra identity-verification steps before approving new credit. It adds friction without fully blocking access.2
The confusing part is that the options have similar-sounding names: credit freeze, credit lock, fraud alert. They are not the same thing, and choosing the wrong one can leave you thinking you are protected when you are actually using something less effective than the free legal option you already have access to.
This article explains what each tool does, how they differ, and when each one makes sense — so you can make an informed choice rather than defaulting to whatever a bureau’s app promotes most prominently.
Credit Freeze vs. Credit Lock: Side-by-Side
| Feature | Credit Freeze (Security Freeze) | Credit Lock |
|---|---|---|
| Cost | Free to place and free to lift — always1 | Depends on the provider and plan — not required to be free1 |
| Legal backing | A right under federal law1 | A product feature governed by provider terms — not a federal legal protection1 |
| How effective? | Restricts access to your credit report for new credit checks2 | Similar goal, but the CFPB states locks are no more effective than freezes1 |
| Where to set it up | Directly with each of the three major bureaus: Equifax, Experian, TransUnion2 | Through each bureau’s app or portal, or a third-party service depending on the product |
| Effect on credit score | None — it controls report access, not the data in your report2 | None — same reason |
| Can you still use existing accounts? | Yes — a freeze only affects new credit checks, not existing accounts2 | Yes — same behavior |
What Is a Credit Freeze?
A credit freeze — sometimes called a security freeze — restricts who can access your credit report. When a lender cannot pull your report, they typically cannot approve a new credit application in your name. This makes a freeze one of the most effective tools available against new-account identity theft.2
In simple terms: think of it as putting a lock on the filing cabinet that holds your credit history. Until you temporarily unlock it, called lifting or thawing the freeze, most lenders cannot see what is inside.
What a credit freeze does NOT do
- It does not affect your existing credit cards or loans — you can still use them normally
- It does not affect your credit score
- It does not stop all forms of identity theft — for example, it would not prevent tax fraud or benefits fraud, which do not rely on a credit check
- It does not prevent existing creditors from accessing your report for account reviews
A freeze specifically targets the most common scenario: someone trying to open a new credit account using your name and personal information.2
What Is a Credit Lock?
A credit lock is a feature offered by credit bureaus — typically through their apps or member portals — that also restricts access to your credit report for new credit checks. On the surface, it sounds like the same thing as a freeze. The practical difference is in the legal foundation and cost.
The CFPB makes this point directly: credit locks are no more effective than security freezes — and freezes are free and a right by law.1 A lock is a product with provider terms that can change. A freeze is a federal legal protection that cannot be taken away or turned into a paid feature.
A lock might make sense if you specifically value the quick toggle experience of a bureau’s app and you have read and accepted the provider’s terms. But if your goal is simply the strongest protection at no cost, a freeze accomplishes that without relying on a third-party product’s terms.1
What Is a Fraud Alert?
A fraud alert is a different kind of tool. Instead of blocking access to your credit report, it flags your report with a notice telling lenders to take extra steps to verify your identity before approving any new credit in your name.2
In simple terms: a freeze says “no entry.” A fraud alert says “check ID before entering.”
Two types of fraud alerts
- Initial fraud alert: Typically lasts one year. Available to anyone who believes they may be at risk of identity theft.2
- Extended fraud alert: Can last seven years. Available to confirmed identity theft victims who provide the required documentation.2
When a fraud alert fits better than a freeze
A fraud alert is worth considering if you are expecting to apply for credit in the near future. Since a fraud alert keeps your report accessible — just with extra verification required — you would not need to lift and re-freeze every time a lender needs to check your report. It adds friction without fully blocking access.
When to Use Each One
| Situation | Best fit | Why |
|---|---|---|
| You want strong default protection and are not applying for credit soon | Credit freeze | Free, federal legal protection, strongest available tool against new-account fraud2 |
| Your SSN or personal data was exposed in a breach | Credit freeze | Fastest way to prevent fraudulent new accounts from being opened2 |
| You want protection but still need to apply for credit soon | Fraud alert | Keeps report accessible while adding identity verification friction2 |
| You confirmed you are an identity theft victim | Extended fraud alert (7 years) | Longer-lasting flag with documentation; also consider a freeze in parallel2 |
| You want the convenience of a bureau’s mobile app toggle | Credit lock with caution | Convenient but not more effective than a freeze — read the provider terms first1 |
| You want to protect a child’s credit file | Child credit freeze | Free and available through each bureau — see section below2 |
How to Place a Credit Freeze (Step by Step)
Placing a credit freeze is free and can usually be done online in a few minutes per bureau. Here is the process at a high level:
- Go to each bureau’s official website directly. Do not use a third-party link you found in an email. Use the official sites:
- Equifax: equifax.com
- Experian: experian.com
- TransUnion: transunion.com
- Create an account or log in on each bureau’s site. You will need to verify your identity — typically your name, address, SSN, and date of birth.
- Navigate to the freeze or security freeze option and follow the steps to place it. You should receive a confirmation.
- Save your login credentials and confirmation details. You will need them to lift the freeze later when you want to apply for credit.
- Repeat for all three bureaus. A freeze at one does not carry over to the others.2
Lifting a freeze (thawing)
When you need to apply for new credit, you will need to temporarily lift the freeze — called a “thaw.” You can usually do this online through the same bureau portal, and you can set it for a specific date window or lift it permanently, then re-freeze afterward. The process is free.2
Protecting a Child’s Credit File
Children can be targets of identity theft precisely because their credit files are clean and go unchecked for years. The FTC notes that parents and guardians can place a free credit freeze for a minor child by contacting each bureau and following their specific minor freeze process.2
Each bureau has its own documentation requirements for minors — typically proof of your identity and your relationship to the child. The exact steps are available on each bureau’s official site. The FTC’s identity theft resources also cover this.2
If Something Looks Wrong on Your Credit Report
If you see an inquiry or an account on your credit report that you do not recognize, treat it as a red flag and investigate it quickly — do not wait to see if it resolves itself.
- Pull your credit reports from all three bureaus. The official free source in the U.S. is AnnualCreditReport.com.
- Identify the company that ran the inquiry or opened the account. Look up their contact information independently — use the company’s official website, not any phone number listed in a suspicious email or letter.
- Contact the company directly and ask why they accessed your report. Errors do happen and can sometimes be resolved quickly.
- If you believe identity theft has occurred, the FTC’s identity theft resources at IdentityTheft.gov walk through reporting steps and next actions, including how to dispute fraudulent accounts and request an extended fraud alert.2
- Consider placing a credit freeze immediately if you have not already — this can stop additional fraudulent accounts from being opened while you investigate.
FAQ
Does placing a credit freeze hurt my credit score?
No. A credit freeze controls who can access your report — it does not change any of the data inside it. Since your score is calculated from the data in your report, not from who has access to it, a freeze has no impact on your score.2
Can I still use my existing credit cards and loans if my credit is frozen?
Yes. A freeze only affects new credit applications — specifically, it prevents lenders from pulling your report to open new accounts. Your existing credit cards, loans, and lines of credit are completely unaffected. You can keep using them exactly as before.2
Is a credit lock stronger protection than a credit freeze?
No. The CFPB is direct on this point: credit locks are no more effective than security freezes — and freezes are free and a legal right. A lock is a product feature with provider terms that can change. A freeze is a federal protection that cannot be charged for or removed as a service.1
If I freeze my credit with one bureau, am I covered everywhere?
No. A freeze only applies to the bureau where you placed it. Since lenders may check any of the three major bureaus — Equifax, Experian, and TransUnion — you need to place a freeze with each one separately to have full coverage.2
How do I apply for a new loan or credit card if my credit is frozen?
You need to temporarily lift or thaw the freeze at the relevant bureau before applying. You can usually do this online through the same bureau portal where you placed the freeze, and you can set the lift for a specific time window. Once that window closes, the freeze goes back into effect automatically. The process is free.2
Does a fraud alert replace the need for a credit freeze?
Not exactly — they serve different purposes. A fraud alert tells lenders to verify your identity more carefully before approving new credit; it does not block access to your report entirely. A credit freeze blocks report access for new credit checks. If you want the strongest protection, a freeze is more restrictive. A fraud alert is a better fit if you need to keep your report accessible for upcoming credit applications.2
What to Do Next
If you have not placed a credit freeze yet and you are not actively applying for credit right now, it takes about ten to fifteen minutes to place one with all three bureaus online — and it is free. Start with the bureau whose site you can find most easily, then work through the other two. Save your login credentials somewhere you will actually be able to find them when you need to lift the freeze later.
If you are planning to apply for a loan or credit card soon, a fraud alert may be a better fit in the short term — it adds verification friction without requiring you to thaw and re-freeze every time a lender needs to check your report.
Either way, the first step is the same: pull your free reports from AnnualCreditReport.com and look at what is already there. Knowing what is on your report is the foundation for everything else.
