A credit freeze restricts access to your credit report, making it much harder for someone to open a new credit account in your name — even with your Social Security number and other personal details, since most lenders won't approve new credit without pulling a report first. It's free, reversible, and one of the more effective tools available against new-account identity theft specifically.
How it actually works
You place a freeze separately with each of the three major bureaus — Equifax, Experian, and TransUnion — since each maintains its own report. Once frozen, a lender attempting to check your credit for a new account application generally can't access the report, which typically causes the application to be denied or paused. Existing accounts you already have continue to work completely normally.
Freeze vs. fraud alert: not the same tool
A fraud alert asks lenders to take extra verification steps before extending credit in your name, but doesn't block access to your report the way a freeze does. A freeze is generally considered the stronger protection, since it prevents report access outright rather than relying on a lender to notice and verify.
Common misconceptions
- It doesn't hurt your credit score — freezing and unfreezing has no impact on the score itself.
- It doesn't stop existing account activity — someone can't freeze you out of your own accounts, and a freeze doesn't prevent using cards you already have.
- It's free by federal law in the U.S. — bureaus cannot charge for placing or lifting a freeze.
- You have to unfreeze temporarily when applying for new credit yourself — most bureaus let you do this online or by phone, often processed quickly, sometimes within minutes for online requests.
When a freeze makes particular sense
A freeze is especially worth considering after a data breach involving your personal information, if you've been a victim of identity theft before, or simply as an ongoing precaution if you're not planning to apply for new credit in the near future. Parents can also freeze a minor child's credit file in most states, which helps prevent child identity theft — a less common but real problem, since a clean, unused file makes fraud harder to detect quickly.
How to place one
- Contact each of the three bureaus separately (Equifax, Experian, TransUnion) — freezing with one does not freeze the others.
- Create an account or verify your identity as required by each bureau's process.
- Confirm the freeze is active — most bureaus provide immediate online confirmation.
- Save the PIN or credentials provided, since you'll need them to lift the freeze later.
A credit freeze isn't a complete identity theft solution — it doesn't stop misuse of accounts you already have — but for the specific problem of someone opening new accounts in your name, it's one of the most effective, lowest-cost protections available.
