A few years back I got a notice that my credit score decreased because of a credit card application made in my name. Long story short, I was able to resolve the issue with the credit card company but it got me thinking on how to prevent this kind of thing happening again. That’s when a learned about “freezing” your credit.
This anti-fraud step is free, takes about twenty minutes, and does more to protect you than almost anything you can buy. The credit bureaus would much rather sell you a monthly monitoring subscription than tell you the free version exists, which is exactly why this guide is worth reading. By the end of it you will have frozen your credit at all three bureaus and will know how to lift it when you actually need to.
What a credit freeze actually does (and what it doesn’t)
A freeze blocks new lenders from seeing your credit report. Since a lender cannot approve a new credit card, loan, or account without pulling your report, a freeze stops a criminal from opening new accounts in your name. New-account fraud is the expensive, hard-to-untangle kind, and this is the thing that stops it.
Just as important is what a freeze does not do. It does not affect your credit score. It does not touch the cards and accounts you already have, which keep working exactly as before. And it does not watch for fraud on those existing accounts. Hold onto that last point, because it matters later.
Freezing is free by federal law. Since 2018, placing and lifting a freeze costs nothing, at every bureau, every time. A freeze does not expire. It stays until you lift it.
Freeze vs. lock vs. fraud alert
The bureaus blur these three on purpose, so let me untangle them.
A freeze is the free one, backed by law. It is the real thing. The only tradeoff is that you have to lift it briefly when you apply for new credit.
A lock is often a paid subscription the bureaus market as “easier” than a freeze. It usually does the same job, but you are paying monthly for something the law already gives you for free. Skip it unless you have a specific reason not to.
A fraud alert is free, lighter, and lasts one year (renewable). Instead of blocking new credit outright, it tells lenders to verify your identity first. Handy detail: you only have to place it at one bureau, and that bureau notifies the other two. A fraud alert is a good complement to a freeze, not a replacement for it.
How to freeze your credit at all three bureaus
You will need your name, address, Social Security number, and date of birth, and sometimes prior addresses. At each bureau you will create an account and receive a PIN or login. Save those somewhere safe. Online is instant; by phone the freeze takes effect within one business day; by mail, within three.
You must do this for all three agencies separately. Freezing one does not freeze the others.
- Equifax — freeze online at Equifax.com, or call 1-888-298-0045.
- Experian — freeze online at Experian.com, or call 1-888-397-3742.
- TransUnion — freeze online at TransUnion.com, or call 1-800-916-8800.
That is the whole job. Three websites, about twenty minutes, no cost.
The part most guides skip: the other agencies
The big three are what lenders check most often, but they are not the only consumer reporting agencies. If you want to be thorough, freeze these too. Each is free.
Innovis is a fourth credit bureau that some lenders also check. Freeze it at Innovis.com or by phone.
NCTUE is the exchange that phone and utility companies use. Freezing it helps stop fraudulent cell phone and utility accounts opened in your name.
ChexSystems is what banks check when you open a checking or savings account. Freezing it helps stop fraudulent bank accounts. You can freeze at ChexSystems.com.
This is the “for the thorough” tier. If you only do the big three, you have still done the thing that matters most.
When and how to lift it, so the freeze doesn’t become a hassle
The reason people avoid freezes is the fear that they will lock themselves out of their own credit. They will not, and this is the part that turns “sounds annoying” into “I will actually do this.”
Lifting a freeze is free and fast, usually instant online. When you apply for a card, a car loan, a mortgage, or a new phone plan, you temporarily lift the freeze, get approved, then let it refreeze. Many bureaus let you set a specific window, a few days, after which the freeze comes back on its own. And if you know which bureau a particular lender uses, you can lift just that one rather than all three. Keep your PINs and logins handy and this takes a minute.
Do this today
Here is the short version you can act on right now:
- Freeze Equifax, Experian, and TransUnion. Save each PIN or login.
- If you want the thorough version, also freeze Innovis, NCTUE, and ChexSystems.
- Store all of those PINs and logins in your password manager, not on a sticky note.
- Freeze your spouse’s credit separately. Freezes are per person.
- Consider freezing credit for children or grandchildren you are responsible for. That is free too, and kids are common fraud targets precisely because no one is watching.
- Know how to thaw before you next apply for credit, so the freeze never feels like a trap.
What a freeze doesn’t cover, and what does
A freeze is a locked front door against someone opening new accounts in your name. It is the strongest free protection you have. But a locked front door does not watch the rooms you already live in. A freeze does not monitor the accounts you already hold, and it will not tell you when your information turns up in a data breach. That ongoing watching is a separate job.
If you decide you want that layer on top of the free baseline, that is what a paid identity theft protection service is for. I wrote a full breakdown of whether one is worth it, and when it is not, in the guide to identity theft protection. Freeze first, since it is free and does the heavy lifting. Then decide whether monitoring is worth it for you.
The bottom line
Freezing your credit is the rare security step that is free, quick, and genuinely effective. Do it once, keep the PINs safe, and thaw when you need to. Anyone trying to sell you a freeze is selling you something you already own.
