How to Freeze Your Credit After SSN Theft: A Step-by-Step Guide

If your Social Security number has been stolen, freezing your credit is the single most powerful action you can take to protect your finances. When a thief has your SSN, they have the master key to your identity. By freezing your credit, you change the locks.

A credit freeze—also known as a security freeze—stops scammers from opening new credit cards, loans, or utility accounts in your name. Since lenders cannot view your credit file while it is frozen, they will almost always reject fraudulent applications on the spot.

Here is exactly how to freeze your credit after SSN theft, what information you need to get started, and how to maintain your defenses.

Quick Answer: The Credit Freeze Checklist

How do I freeze my credit after my SSN is stolen? To freeze your credit, you must contact all three major credit bureaus individually. This process is 100% free under federal law. You can request freezes online, by phone, or by mail:

1. Equifax: Create an account at Equifax.com/personal/credit-report-services or call 1-888-298-0045.

2. Experian: Go to Experian.com/freeze or call 1-888-397-3742.

3. TransUnion: Visit TransUnion.com/credit-freeze or call 1-888-909-8872.

What a Credit Freeze Does (and Doesn’t Do)

Before you begin, it is important to understand how a security freeze operates:

• What it does: It completely locks your credit report. Only existing creditors and government agencies can see it. If a scammer attempts to apply for a loan or open a store card using your SSN, the lender’s credit check will be blocked, and the application will be denied.

• What it doesn’t do: It does not affect your current credit card or loan accounts. If a thief gets hold of an existing credit card, a freeze cannot stop them. You must continue to monitor your existing statements.

• Impact on your score: A credit freeze has absolutely zero impact on your credit score.

What You Need Before You Start

To freeze your credit, you will need to verify your identity. The bureaus must ensure that you are the one requesting the lock, not the thief. Before starting, have this information ready:

• Your full legal name, date of birth, and Social Security number

• Your current address (and previous addresses if you have moved within the last two years)

• A mobile phone number (to receive verification security codes)

• A pen and paper (or a secure digital manager) to record newly created account credentials and PINs

If you choose to file by mail, you will also need to send photocopies of government-issued photo ID and proof of address (like a utility bill or bank statement). Because of this extra paperwork, freezing your credit online or by phone is significantly faster.

Step-by-Step: Freeze Your Credit at All 3 Bureaus

To guarantee full protection, you must place a freeze with each bureau individually. If you only freeze one or two, a thief can find a lender that pulls from the unsecured bureau and open accounts anyway.

Step 1: Equifax

• Online (Fastest): Go to Equifax.com/personal/credit-report-services. Click on “Place a security freeze.” You will create a “myEquifax” account where you can manage your freeze status.

• By Phone: Call the Equifax automated system at 1-888-298-0045 or customer service at 1-888-378-4329.

• By Mail: Download the Equifax Security Freeze Request form, fill it out, and mail it with your identity documents to:

  Equifax Information Services LLC, P.O. Box 105788, Atlanta, GA 30348-5788

Step 2: Experian

• Online (Fastest): Visit Experian.com/freeze and click “Add a freeze.” You can freeze your own report or freeze a report on behalf of a minor or dependent. You will make an Experian account.

• By Phone: Call 1-888-397-3742 (1-888-EXPERIAN) and follow the automated prompts.

• By Mail: Send your written request with required documentation to:

  Experian Security Freeze, P.O. Box 9554, Allen, TX 75013

Step 3: TransUnion

• Online (Fastest): Go to TransUnion.com/credit-freeze and click “Add a Freeze.” You will set up a TransUnion Service Center account.

• By Phone: Call 1-888-909-8872 or 1-800-916-8800.

• By Mail: Send a written request along with photocopies of your identifying documents to:

  TransUnion, P.O. Box 160, Woodlyn, PA 19094

What Not to Do After Your Credit Is Frozen

• Do not lose your login credentials or PINs: When you initiate a freeze, the bureaus might issue a PIN or require you to create an online account. Keep this information extremely secure. You will need it to temporarily “unfreeze” or “thaw” your credit when you want to apply for a legitimate loan, a new apartment, or a credit card.

• Do not confuse a “credit freeze” with a “credit lock”: Bureaus often push paid “locks” or subscription monitoring services during the freeze process. Ignore these up-sells. A credit freeze is a free, federally regulated consumer right that offers equivalent or stronger security.

• Do not forget about secondary bureaus: While the big three are the most important, you can also freeze your files with specialty consumer reporting bureaus like ChexSystems (to stop fraudulent bank accounts from being opened) and the National Consumer Telecom and Utilities Exchange (NCTUE) to stop utility fraud.

What Next? Check and Keep Up Your Defenses

A credit freeze is your frontline defense, but identity recovery doesn’t stop here:

1. Request Your Free Credit Reports: After implementing the freezes, visit AnnualCreditReport.com to download free copies of your credit files. Check them meticulously for any fraudulent accounts that might have already been opened before your freeze took effect.

2. File an FTC Report: Go to IdentityTheft.gov to document the SSN compromise. They will generate an official Identity Theft Report, which you will need to dispute and close any unauthorized accounts you find.

3. Keep Your File Frozen: Leave your credit frozen indefinitely. There is no penalty, and you can easily thaw your credit instantly online when needed.

Frequently Asked Questions

Is there a fee to freeze my credit?

No. Since 2018, federal law has made it completely free to freeze, unfreeze, or temporarily thaw your credit reports at Equifax, Experian, and TransUnion.

How long does it take for a credit freeze to go into effect?

When you make your request online or by phone, the freeze must go into effect within one hour. If you submit your request by mail, the bureau must place the freeze within three business days of receiving your request.

How do I temporarily lift my credit freeze?

If you are buying a car, applying for a loan, renting an apartment, or signing up for a utility, you will need to “thaw” your credit. Log into your accounts at Equifax, Experian, and TransUnion, and select the option to lift the freeze temporarily. You can set the lift to expire after a certain number of days, after which your files will automatically lock again.

Should I get a fraud alert instead?

While a fraud alert is good (it warns lenders to verify your identity), it does not actually stop lenders from checking your file. A credit freeze is far safer for victims of SSN theft because it actively blocks access to your file, making it much more difficult for identity thieves to commit fraud.

Final Takeaway

Securing your credit after an SSN compromise might seem like a lot of work, but the online systems make the process of placing a credit freeze straightforward. Always initiate your freezes online if you can, avoid paying for optional locks, and keep your login information safe. This crucial shield will prevent unauthorized accounts from ruining your financial reputation while you recover from identity theft.
