Credit Freeze vs. Fraud Alert: Which One Actually Stops a Thief?

A freeze blocks new credit in your name. An alert only asks lenders to check twice. Both are free by federal law, both take minutes, and the one most people reach for is the weaker of the two.

Key takeaways

  • A security freeze blocks lenders from pulling your report, so an application in your name goes nowhere. It is free at all three bureaus.
  • A fraud alert does not block anything. It tells lenders to take extra steps to verify who is applying.
  • Requested online or by phone, a bureau must place a freeze within one business day and lift it within one hour.
  • Freezing is not one action but three: Equifax, Experian and TransUnion each hold a separate file.

The short answer

If you want new credit in your name to be impossible to open, freeze your reports. A frozen file cannot be pulled by a lender who does not already have a relationship with you, and a lender that cannot pull a file almost never approves an application.

A fraud alert is the lighter version. It leaves your file open and attaches a note asking the lender to verify your identity before extending credit. It relies on the lender doing something, which is exactly the part you cannot control.

What each one actually does

The practical difference is who has to act. A freeze acts on the file itself. An alert acts on the checklist the lender is supposed to follow.

Free, and fast, because the law says so

Since 21 September 2018, federal law makes freezes free at all three nationwide credit reporting companies. Before that date several states let bureaus charge a fee for the privilege of locking your own data.

The same law sets deadlines. Ask online or by phone and the bureau has one business day to place the freeze and one hour to lift it. Ask by mail and it has three business days either way.

You can also freeze the file of a child under 16, and of an adult you hold power of attorney or guardianship for. A child with no credit history is a quiet target precisely because nobody thinks to check it.

  • Equifax, Experian and TransUnion each keep their own file. Freezing one does nothing to the other two.
  • A temporary thaw is free and can be set for a window of days, which is what you want when you are shopping for a loan.
  • A freeze does not affect your credit score, and it does not stop you using the cards and loans you already have.

The three kinds of fraud alert

Alerts are not one product. Which one you qualify for depends on what has happened to you, and only one of them lasts more than a year.

  • Initial fraud alert: one year, no proof required, for anyone who suspects they are at risk. Renewable.
  • Extended fraud alert: seven years, but you have to file an identity theft report to get it.
  • Active duty alert: one year, for deployed service members. It also takes your name off pre-screened credit offers for two years.

What a freeze does not cover

A freeze protects against new credit opened in your name. It does nothing about fraud on the accounts you already have, which is most of it.

It also does not touch the specialty reports that sit outside the big three: the checking-account screening files, the insurance claim history, the employment screening databases. Those have their own dispute processes and their own request forms.

Frequently asked questions

Does freezing my credit hurt my score?

No. A freeze restricts who can see the file; it does not change what is in it. Your score is unaffected, and so are the accounts you already hold.

Is a credit lock the same as a freeze?

No. A freeze is a right created by federal law, with deadlines attached to it. A lock is a product a bureau sells or bundles, governed by its own terms of service rather than by statute. They feel similar and they are not the same thing.

Do I have to freeze all three bureaus?

Yes, if you want the protection to be real. A lender typically pulls one report, and you have no way to know which. Leaving one file open leaves one door open.

What happens when I want a new card while frozen?

You thaw the file first — permanently or for a set window — then apply. Requested online or by phone the lift takes at most an hour, so it is a nuisance rather than an obstacle.
