Your Social Security number is the key to your financial and legal identity in the United States. Unlike a credit card number, it cannot be changed. Once it is stolen, the damage unfolds over months or years — tax fraud, fraudulent credit accounts, medical identity theft, and government benefits fraud. The response plan matters, and it starts immediately.
If your SSN has been stolen, take these steps in order: freeze your credit at all three bureaus, place an IRS Identity Protection PIN, file an identity theft report at IdentityTheft.gov, report to the SSA, and monitor all three credit bureaus. Act fast — the window before fraudulent accounts open is short.
Step 1: Freeze Your Credit at All Three Bureaus
A credit freeze prevents any new credit from being opened in your name — period. It is free at all three bureaus and takes about 10 minutes total. Do all three. A freeze at one does not protect the others.
Step 2: Get an IRS Identity Protection PIN
Tax identity theft — where someone files a tax return using your SSN and collects your refund — is one of the most common forms of SSN fraud. An IRS IP PIN is a six-digit number that must be included on your tax return before the IRS will process it. Without the PIN, fraudulent returns filed with your SSN are rejected.
Apply at IRS.gov IP PIN program. The PIN changes every year and is delivered to you in January. If your SSN has been exposed, getting an IP PIN should happen within days — not after you discover a fraudulent return was already filed.
Step 3: File an Identity Theft Report
Go to IdentityTheft.gov — the FTC's official identity theft recovery site. Filing here creates an official report, generates a personalized recovery plan, and provides documentation that businesses and government agencies are required to accept when you dispute fraudulent accounts.
Step 4: Report to the Social Security Administration
Report SSN fraud to the SSA at SSA Office of Inspector General. Review your Social Security earnings record at ssa.gov/myaccount for any wages or employment you do not recognize — someone may be using your SSN for employment.
Step 5: Long-Term Monitoring
SSN theft has long tails. Fraudulent accounts may not appear for months. Set up ongoing monitoring: check your credit reports at AnnualCreditReport.com weekly, consider a paid identity protection service for comprehensive monitoring and restoration support.
