TL;DR: Pull your free credit reports from all three bureaus via AnnualCreditReport.com and look for any account, loan, or credit inquiry you don't recognize.
How to Check If Your SSN Was Used to Open an Account — a clear, step-by-step guide to what to do and how long it takes.
Step 1: Check your credit reports for unfamiliar accounts
Pull your free credit reports from all three bureaus via AnnualCreditReport.com and look for any account, loan, or credit inquiry you don't recognize.
Step 2: Check your Social Security earnings statement
Log into or create your account with the Social Security Administration and review your earnings record — wages listed from an employer you've never worked for is a strong sign your SSN was used elsewhere.
Step 3: Watch for IRS notices
An IRS notice about income from an employer you don't recognize, or a rejected e-filed return because one was already filed under your SSN, both indicate your number may have been used fraudulently.
Step 4: Check for denied benefits or unexpected notices
Denial of a loan, benefits application, or government service you didn't apply for can also indicate your SSN was already used, sometimes fraudulently, elsewhere.
Step 5: Report any confirmed misuse promptly
If you find evidence of misuse, file a report at IdentityTheft.gov to get an official FTC Identity Theft Report and a personalized recovery checklist.
