Someone steals your Social Security number. A week later a lender you have never heard of runs your credit. Two tools exist to make that harder: a credit freeze and a fraud alert. They sound alike. They do different jobs.

Federal consumer advice resources offer guidance on fraud alerts and credit freezes for identity theft protection.

The Federal Trade Commission covers both on one page, Credit Freezes and Fraud Alerts. This article draws on that page's title and on one FTC alert. The text of those pages was mostly cut off in our review, so the mechanics below are general background. Confirm each detail on the FTC page and with the bureaus before you act.

What a Credit Freeze Does

A freeze is the heavier tool. In general terms, it restricts access to your credit report so a new lender cannot pull it. Most lenders check a report before approving an account. If they cannot see it, a thief using your name usually stalls.

The FTC treats the freeze as a direct defense. A consumer alert from September 2025 is titled Get a credit freeze to stop identity thieves. The headline alone tells you where the agency stands. It wants people to consider one, especially after a data breach.

A freeze generally does not hurt your score and does not touch accounts you already have. It also does not stop every kind of fraud. Someone who takes over an existing card is a separate problem, so keep watching your statements.

What a Fraud Alert Does

A fraud alert is the lighter tool. It is commonly described as a flag on your file that tells lenders to verify your identity before opening new credit. The file stays open. The lender just has to take an extra step, such as calling you.

Alerts are usually described in two forms. An initial alert is often said to last one year. An extended alert is often said to last seven years and generally requires an identity theft report. Those durations are not in the pages we could read, so check them on the FTC site before relying on them.

The practical trade is simple. An alert adds friction for a thief but still lets lenders in. A freeze shuts the door but requires you to open it yourself when you apply for credit.

Which One Fits Your Situation

The FTC pages we reviewed do not compare the two or tell you how to choose. So here is a plain way to think it through. Ask yourself a few questions.

  • Has your data already been misused? If yes, the FTC's identity theft resources are the place to start, and a freeze is a common next step.
  • Are you about to apply for a mortgage or car loan? A freeze means you must lift it first. Plan for that, and ask the bureau how long lifting takes.
  • Do you want a lighter touch? An alert may suit someone who wants lenders to double check without locking the file.

Nothing says you must pick only one. Many people place an alert and later add a freeze, or the reverse. The right call depends on how soon you need new credit and how worried you are about misuse.

What to Confirm Before You Act

Here is what the sources we could read do not tell you. They do not define either tool in full. They give no costs, no steps for placing or lifting, and no bureau contact details. The FTC PDF titled Fraud Alert/Credit Freeze came through as unreadable data, so we drew nothing from it.

That leaves a short checklist. Open the FTC page and read the current rules on cost and duration. Federal law is widely reported to make freezes free, but verify that yourself. Then contact each of the three nationwide credit bureaus directly, since a freeze is generally placed with each one separately. Alerts are often described as passing from one bureau to the others, but confirm that too.

Write down every PIN or password the bureaus give you. A lost freeze PIN is a small headache that can turn into a delayed loan. Keep the records somewhere safe, like the folder of home paperwork in the photo above.

Last, set a reminder. If you place an alert, note its end date. If you place a freeze, note where the lift instructions live. Ten minutes of setup now saves a scramble later.
