Do You Have to Freeze Your Credit With All Three Bureaus to Prevent Identity Theft?

Yes, freeze all three. Nothing forces you to, but a freeze at one bureau protects only that bureau’s file. Lenders can pull from any of the three, so a thief just needs one that’s open. Freezes are free, can be done online in one sitting, and don’t touch your credit score. Here’s how to do it, and what a freeze can’t stop.

Do You Have to Freeze Your Credit at All Three Bureaus?

No law forces you to. But you should, because a freeze only locks the file at the bureau where you placed it, and the CFPB says you have to contact each nationwide bureau separately.

Lenders don’t all check the same bureau. If you freeze only one, a thief’s application can still reach a credit file you left open. That gap is the whole reason to freeze all three.

One exception: a fraud alert works differently. You place it at one bureau, and that bureau must notify the other two, but freezes don’t work that way.

How a Credit Freeze Stops Identity Theft

A freeze blocks the credit check. Lenders typically won’t offer credit they can’t check, so a thief with your Social Security number hits a wall, and so do you until you lift the freeze.

You don’t need a breach first. The FTC says anyone can freeze their credit at any time, even if their identity hasn’t been stolen and their data hasn’t leaked. If your Social Security number has ever appeared in a breach notice, and it probably has, this is your move.

How to Freeze Your Credit at Equifax, Experian and TransUnion

1. Gather your details. You’ll need your full name, address, date of birth and Social Security number.
2. Open each bureau’s site. Use Equifax, Experian and TransUnion. Phone and mail options exist too, and Equifax (800-685-1111) and Experian (888-397-3742) take freeze requests by phone. Use the number on TransUnion’s site, since its listings have changed.
3. Create or sign in to an account. Equifax requires you to be 18 to create a myEquifax account.
4. Choose the freeze option. Answer the identity-verification questions.
5. Save every login and PIN. You’ll need them to lift the freeze later.
6. Repeat at the other two. Screenshot each confirmation.

Online and phone requests must be placed within one business day, so don’t panic if it isn’t instant. Three sites, three logins, one sitting.

Should You Freeze the Smaller Reporting Agencies Too?

Most people stop at three. Doing more closes gaps the big three don’t.

Other companies keep files that lenders and service providers use. A freeze at Equifax, Experian and TransUnion doesn’t carry over to them. The CFPB publishes a list of them.

• Innovis: another credit bureau, used by creditors for identity verification. Freeze at innovis.com/personal/securityFreeze.
• NCTUE: telecom, pay TV and utility payment history. Freeze at nctue.com.
• ChexSystems: checking and savings account history. A freeze can keep a thief from opening a bank account in your name. Go to chexsystems.com.
• LexisNexis Risk Solutions and SageStream: one portal at consumer.risk.lexisnexis.com/freeze covers both, and only those two. It won’t freeze Equifax, Experian, TransUnion or Innovis.

Prices and rules vary by company and state, so check each site before you submit.

What a Credit Freeze Won’t Stop

A freeze blocks new accounts. It doesn’t guard the ones you already have.

• Existing accounts: a thief can still use a stolen card number or take over your online banking.
• Existing creditors and collectors: they can still see your report, and government agencies can in limited situations.
• Tax fraud: a freeze doesn’t stop someone from filing a return with your Social Security number.

That means watching your statements still matters. Honestly, that’s the part people forget once the freeze is on.

Credit Freeze vs. Fraud Alert: Which One Do You Need?

You can use both. The FTC says you can add a fraud alert even if you already have a freeze.

	Credit freeze	Initial fraud alert	Extended fraud alert
What it does	Blocks new lenders from seeing your report	Tells lenders to verify your identity before opening credit	Same, plus removal from marketing lists for five years
Who can place it	Anyone	Anyone who is or suspects they’re affected by identity theft	Identity theft victims with an FTC report or police report
How long	Until you lift it	One year, renewable	Seven years
Where	All three bureaus	One bureau (it notifies the other two)	One bureau (it notifies the other two)
Cost	Free	Free	Free

Bureaus also sell app-based “locks.” Freezes are the federally regulated option.

How to Lift a Credit Freeze When You Need Credit

You’ll need to lift it to apply for credit, a job, an apartment or insurance. Ask the lender which bureau it uses, lift the freeze only at that one, and put it back afterward.

Online and phone lifts must be done within one hour. You can still get your own free credit reports while frozen.

How to Freeze Your Child’s Credit

If your child is under 16, you can request a free freeze. The process differs from an adult’s, and each bureau has its own instructions.

Guardians and people with power of attorney can also request freezes for the person they act for. Child identity theft can go unnoticed for years, and a frozen file makes new accounts harder to open.

Two Free Steps That Work With a Freeze

Get an IRS Identity Protection PIN. It’s a six-digit number that prevents someone else from filing a tax return with your Social Security number. Anyone with an SSN or ITIN who can verify their identity can get one, and it’s free.

Check your credit reports. Accounts you don’t recognize can signal identity theft, so review your free reports at AnnualCreditReport.com.

Got a Data Breach Notice? Freeze First, Then Read the Fine Print

Breach letters usually offer free credit monitoring. Monitoring tells you after something happens, while a freeze blocks it before it does.

Some settlements offer only limited monitoring. The Asheville Eye Associates data breach settlement, for example, offered one year of one-bureau monitoring. Our Conduent breach coverage and Prosper data breach lawsuit guide walk through how monitoring offers work. Federal employees can also read what to do as OPM identity protection expires.

Freezing costs nothing and doesn’t stop you from checking whether a data breach compensation claim is open.

If Someone Already Used Your Identity

Report it at IdentityTheft.gov, then place an extended fraud alert and freeze all three bureaus. The FTC says an extended alert requires an FTC identity theft report or a police report.

If someone opened accounts in your name, a consumer rights lawyer can explain your options. Many offer a free legal consultation.

Credit Freeze — Frequently Asked Questions

1. Do I need to freeze all three credit bureaus?

 Not by law, but you should. A freeze only locks the file at the bureau where you place it, so freezing one leaves two open. Fraud alerts are the exception, because the bureau you contact notifies the other two.

2. Does a credit freeze hurt my credit score?

 No. The FTC says a freeze doesn’t affect your credit score and doesn’t stop you from using existing credit cards. It only blocks new lenders from seeing your report until you lift it.

3. Is a credit freeze better than a fraud alert?

 A freeze blocks lenders from seeing your report, while an alert asks them to verify your identity first. The FTC says a freeze is always a good idea, and you can use both at once.

4. How long does a credit freeze last?

 Until you lift it. An initial fraud alert lasts one year, while an extended alert lasts seven years and needs an identity theft report.

5. Is it really free to freeze and unfreeze my credit?

 Yes. Free freezes have been federal law since September 21, 2018. The FTC lists no cost to place or lift a freeze at the three nationwide bureaus.

6. How do I unfreeze my credit temporarily?

 Contact the bureau the lender uses and lift the freeze there. Online and phone lifts must be done within one hour. Then put the freeze back once the credit check is done.

7. Can I still check my credit report while it’s frozen?

 Yes. A freeze doesn’t stop you from getting your own report, including your free annual reports. It only blocks new lenders from seeing it.

8. Will a freeze stop tax fraud or misuse of my existing cards?

 No. A freeze blocks new accounts only. An IRS IP PIN helps prevent tax-return fraud, and you still need to watch your existing accounts.
