Do You Need to Freeze Credit With All 3 Agencies?

Yes. To fully protect yourself, you need to freeze your credit with all 3 bureaus — Equifax, Experian, and TransUnion — by contacting each one separately. Each bureau keeps its own file on you, and a freeze placed at one has no effect on the other two. Federal law makes every freeze free to place and free to lift, however many times you do it.

Why One Freeze Doesn’t Cover the Others

Equifax, Experian, and TransUnion are independent, competing companies. They do not share security freeze information with each other, so a freeze at one bureau leaves your file wide open at the other two.¹

That matters because of how lenders check credit. When someone applies for a new account, the lender usually pulls a report from just one bureau, and you have no way to predict which. Freeze two of the three, and a thief who happens to apply with a lender that uses the unfrozen bureau can still get approved in your name.

Fraud alerts work differently. Place a fraud alert at any one of the three bureaus, and that bureau is required by law to notify the other two.² No similar rule exists for freezes. Three bureaus means three requests.

How to Place the Freeze at Each Bureau

You can place a freeze online, by phone, or by mail. Each bureau will ask for your full legal name, Social Security number, date of birth, and current and previous addresses. You may also need a copy of a government-issued ID or a recent utility bill, especially if you have moved recently or have a thin credit history. Give the information exactly as it appears on your legal documents; mismatches trigger extra verification.

Equifax: equifax.com/personal/credit-report-services/credit-freeze, or 888-298-0045.³
Experian: experian.com/freeze, or 888-397-3742.⁴
TransUnion: transunion.com/credit-freeze, or 888-909-8872.⁵

Each bureau’s online portal uses two-factor authentication, sending a verification code by text message or email. If the automated verification can’t confirm your identity, you may have to mail photocopies of your Social Security card along with a bank statement or utility bill.

A freeze costs nothing. Federal law requires the three nationwide bureaus to place and remove freezes free of charge, whether you request them online, by phone, or by mail. A freeze also has no effect on your credit score.⁶

How Fast the Freeze Takes Effect

If you request the freeze online or by phone, the bureau must place it within one business day. By mail, the bureau has three business days after receiving your letter.⁷ You should receive written confirmation within five business days after the freeze is in place.¹

Save Your PINs and Logins

Each bureau will give you a confirmation number, create an account login, or issue a PIN. You will need these credentials later to lift or remove the freeze, so store them somewhere secure like a password manager or locked file. Losing them can delay you when you need credit quickly. TransUnion no longer requires a PIN for phone or mail changes, verifying identity instead through personal information and security questions.⁸

What the Freeze Actually Blocks

A freeze prevents new creditors from viewing your credit report, which stops almost anyone — including you — from opening new accounts while it is active.⁶ Since most lenders will not approve an application without pulling a report, the freeze shuts down fraudulent accounts before they open.

Several parties keep access even while a freeze is in place:¹

Banks and credit card companies you already have accounts with.
Child support enforcement agencies and certain other government entities.
Credit monitoring services you have hired.

The federal freeze law also does not apply to employment screening, tenant screening, or insurance underwriting.¹ You generally do not need to lift a freeze to apply for a job, rent an apartment, or get an auto insurance quote.

Lifting the Freeze When You Need Credit

When you want to apply for a loan, mortgage, or credit card, you need to temporarily lift (sometimes called a “thaw”) or permanently remove the freeze at the relevant bureau. Use the same online portal, phone number, or mailing address where you placed it, and have your PIN or account login ready.

You have two ways to lift it:

A time-based lift, where you pick a date range and the freeze automatically snaps back into place when the window closes.
A creditor-specific lift, where you authorize one particular lender while keeping everyone else locked out.

Federal law requires bureaus to lift a freeze within one hour when you request it online or by phone. Mail requests take up to three business days after the bureau receives your letter.⁷ There is no fee, no matter how often you do it, and a freeze stays in place indefinitely until you lift or remove it yourself.¹

Smaller Bureaus Worth Freezing Too

Equifax, Experian, and TransUnion handle most credit decisions, but several smaller agencies track specialized data that identity thieves can exploit. Freezing these closes gaps the big three leave open.

Innovis

Innovis is a fourth consumer credit bureau used by some lenders. Place a free freeze at innovis.com/securityFreeze or by calling 800-540-2505.⁹

ChexSystems

ChexSystems tracks checking and savings account history. Banks and credit unions check it before approving new deposit accounts, so a freeze here blocks fraudulent bank accounts opened in your name. Request a freeze through the ChexSystems Consumer Portal, by calling 800-887-7652, or by mail.¹⁰

NCTUE

The National Consumer Telecommunications and Utilities Exchange tracks payment history with phone companies and utility providers. Freezing your NCTUE file makes it harder for someone to open fraudulent cell phone or utility accounts. Call 866-349-5355 or send a request by mail.

Freezing Credit for a Child Under 16

Children are frequent identity theft targets because the fraud often goes undetected for years. Federal law lets parents and legal guardians place a security freeze on behalf of a child under 16. If the bureaus do not already have a file for the child — common since most minors have no credit history — they must create one solely to freeze it, and that file cannot be used for any credit purpose.¹¹

You will need to prove your authority over the child, typically with a birth certificate. A child welfare or probation agency representative acting for a young person in foster care must show official documentation certifying the child is in the agency’s care.¹¹ As with your own file, you need to submit a separate request to each bureau.
