What to Do if Your Social Security Number Was Exposed: A Complete Guide
A compromised Social Security number can pose serious and lasting risks, as it may be used to open fraudulent accounts, obtain credit or loans, access benefits, or commit other forms of identity theft. Many state privacy and data breach laws treat Social Security numbers as sensitive personal information. Depending on the circumstances, people affected by a data breach may have legal claims for financial losses, identity theft, privacy harms, or other legally recognized injuries.

What Should You Do Immediately After Your Social Security Number Is Exposed?
If your Social Security number was exposed in a data breach, there are steps to take to protect your identity even if it has not been misused yet. The most important steps to take are checking, freezing, and monitoring your credit. Additionally, save all breach notices and any suspicious account or credit activity—this may serve as evidence if you decide to take legal action.
Read the Data Breach Notice Carefully
The data breach notice you receive after a security incident may identify what information was exposed, when the breach occurred, what services the company is offering in response, and how you can enroll in credit monitoring.
Save All Breach-Related Documents
Save the data breach notice, emails, screenshots, credit monitoring offers, fraud alerts, suspicious account notices, and any proof of financial or identity-related harm. After the breach, don’t respond to unexpected calls, texts, or emails. Scammers may pretend to be from the government or a business you know.
Place a Credit Freeze or Fraud Alert
A credit freeze restricts access to a person’s credit report, while a fraud alert requires creditors to take extra identity-verification steps before opening new accounts. The Consumer Financial Protection Bureau notes that an initial fraud alert lasts up to one year unless removed sooner.
You can also create a personal My Social Security account to keep track of your records and identify suspicious activity. The Social Security Administration also allows users to add blocks to their accounts, such as an eServices block (which prevents changes to online information) or a direct deposit fraud prevention block (which prevents changes to direct deposit information).
Check Your Credit Reports
Review your credit reports for unfamiliar accounts, hard inquiries, loans, or addresses. The FTC specifically recommends ordering free credit reports and checking for accounts you do not recognize after your Social Security number is exposed.
Report Identity Theft if Your SSN Was Misused
If someone used your Social Security number to open an account, make a purchase, apply for a loan, or obtain benefits, report identity theft via IdentityTheft.gov. The Federal Trade Commission (FTC) collects identity theft complaints and provides resources for those whose SSNs may have been exposed in a breach.
Take Advantage of Free Credit Monitoring if Offered
Many companies offer free credit monitoring or identity theft protection after a data breach. Consider enrolling in these services, but understand that monitoring does not undo the exposure of your personal information.

Can You Sue If Your Social Security Number Was Exposed in a Data Breach?
Across the U.S., consumers’ data and identities are protected by a variety of state and federal data breach laws. You may be eligible to file a data breach lawsuit if a company failed to use reasonable security measures, delayed notifying victims, ignored known vulnerabilities, or exposed highly sensitive information like your Social Security number.
Statute of Limitations for Social Security Number Data Breach Claims
The statute of limitations, or filing deadline, for a Social Security number data breach claim depends on the state you live in and the type of claim you intend to file, be it a lawsuit or an arbitration demand.
Mass Arbitration or Class Action Lawsuit?
Victims of data breaches may be able to take legal action through a class action lawsuit or a mass arbitration action. The action you may take often depends on the terms of service or contract you signed with the affected company–these terms often include waivers that prohibit consumers from filing class actions.
Mass arbitration occurs when multiple individual arbitration demands are filed against the same company, coordinated in large numbers. The involved parties base their claims on alleged company misconduct and seek financial compensation. In class actions, multiple claims are consolidated into a single lawsuit, allowing the court to resolve many similar claims simultaneously. An experienced attorney can help you decide which option fits your case.
Should I Start a New Legal Action or Join an Existing One?
After your Social Security number is compromised in a data breach, you may be able to start a new class action lawsuit or mass arbitration, or join an existing one. In a class action lawsuit, a group of similarly affected individuals files a lawsuit against a company, and any settlement is divided evenly among participants. In a mass arbitration, many affected individuals file individual arbitration demands against a company at the same time, with settlements decided on each case’s merits.
There may already be an existing class action lawsuit or mass arbitration regarding the data breach in which your information was exposed. If that is the case, joining the action is simple on the Class Action U website. If there is no legal action yet for your breach, our legal partners can help you decide whether your case merits a legal filing.
