Three tools that sound similar and do completely different jobs. One prevents fraud, one flags it, one tells you after it already happened. People often buy the weakest one and skip the strongest, mostly because the strongest is free and nobody advertises free things.
Credit freeze — the strong one
A freeze locks your credit report so new lenders can’t pull it. Since virtually no lender will open an account without pulling credit, this blocks new-account fraud outright.
It’s free by federal law. Free to place, free to lift, free to place again. You do it separately with Equifax, Experian and TransUnion — three accounts, about fifteen minutes total.
The trade-off is friction, and it’s smaller than people expect. When you’re applying for something, you temporarily lift the freeze, usually online or in the app, often taking effect within minutes. You can lift with one bureau only if you know which one the lender uses, or lift all three for a few days.
A freeze doesn’t affect your score, doesn’t stop you from using existing accounts, and doesn’t block your own access to your report.
Worth doing for your kids too. Child identity theft goes undetected for years because nobody checks a nine-year-old’s credit.
Fraud alert — the middle one
A fraud alert asks lenders to take extra steps to verify your identity before extending credit. It’s a flag, not a lock — a lender can still open the account, they’re just supposed to verify first.
Free, lasts one year, renewable, and you only need to contact one bureau because they’re required to notify the other two. Identity theft victims can get an extended seven-year alert with documentation.
Less protective than a freeze, less friction. A reasonable choice if you apply for credit frequently.
Credit monitoring — the weak one
Monitoring watches your reports and alerts you to changes: new accounts, inquiries, address changes. It’s detection, not prevention. By the time you get the alert, the account exists.
That’s still useful — catching fraud in week one instead of month eight matters a lot for cleanup. Just don’t mistake it for protection.
And don’t pay much for it. Free monitoring is widely available through credit card issuers, banks, and free credit apps. The paid identity-theft services bundle in restoration help and insurance, which has some value if you’d rather not handle a cleanup yourself, but the core monitoring function isn’t worth $25 a month.
What most people should do
Freeze all three bureaus. Add free monitoring through whatever your bank or card issuer offers. Skip the paid subscription unless you specifically want the restoration service.
That combination is prevention plus detection, and it costs nothing.
One more free thing
Pull your reports at AnnualCreditReport.com periodically. Freezes and alerts don’t tell you about errors that are already there, and errors are common. Reading the actual report once a year is the habit that catches what the tools miss.
