You cannot legally obtain someone else's Social Security number without their permission

A Social Security number is not public information. The Social Security Administration does not publish them, does not confirm them over the phone to strangers, and does not allow third parties to search for them. If you have found a website claiming to reveal someone's SSN for a fee, that site is either a scam or selling information obtained illegally.

The only legitimate ways to learn someone's Social Security number are: they tell you directly, they provide it on a form you both sign, or you are their employer or financial institution with a legal reason to have it on file. If you need their number for a specific transaction — a loan process, a job, insurance, or a court matter — you ask them for it directly.

If you are trying to verify someone's identity or locate them for a lawful reason, there are legal alternatives that do not require their SSN.

Key Takeaways

  • Social Security numbers are protected information, and searching for someone else's number without permission is illegal under the Fair Credit Reporting Act and state privacy laws.
  • Websites offering to reveal someone's SSN are scams, data brokers selling stolen information, or both — paying them puts your own identity at risk.
  • If you need someone's number for a legitimate reason like employment or lending, you request it directly from that person.
  • To verify identity or locate someone legally, use public records searches, background check services that operate within the law, or hire a licensed private investigator.
  • If you suspect someone has stolen your SSN or someone else's, report it to the Social Security Administration and the Federal Trade Commission.

Why SSNs are protected and what the law says

The Fair Credit Reporting Act (FCRA) restricts who can access Social Security numbers and for what purpose. The law says you cannot obtain someone's SSN through deception, cannot buy it from a data broker without a legitimate business reason, and cannot use it to locate or identify someone without their knowledge. Violating the FCRA can result in civil lawsuits and criminal charges.

Most states also have their own privacy laws that go further. California, New York, and others prohibit the public display of SSNs, restrict how businesses can collect them, and give people the right to know when their number has been compromised. Attempting to obtain someone's SSN without consent violates these laws even if you never use the number.

The reason for these protections is straightforward: a Social Security number is the master key to identity theft. Once someone has it, they can open credit accounts, file tax returns, take out loans, and drain bank accounts in your name. Keeping SSNs private is the first line of defense against that harm.

Why "people search" websites and paid lookup services do not work

You may have seen ads for websites that claim to reveal anyone's Social Security number for $9.99 or $19.99. These fall into three categories: outright scams that take your money and deliver nothing, data brokers selling information obtained illegally from data breaches, and sites that collect information you voluntarily enter and sell it to marketers.

None of them have access to real Social Security numbers. The Social Security Administration does not sell data. Banks, employers, and government agencies do not sell SSNs to third parties. If a website shows you a number, it is either fabricated, stolen from a breach years ago, or belongs to someone else entirely. Paying for these services does not get you the information — it gets you on a list of people willing to pay for illegal data, which makes you a target for follow-up scams.

Worse, entering your own information into these sites to search for someone else puts your identity at risk. Many of these operations are run by criminals or sell your data to them. You end up compromising your own security to get nothing in return.

Legal ways to verify someone's identity

If you need to confirm that someone is who they claim to be — for hiring, lending, or a business transaction — there are lawful paths. Ask them directly for their SSN if you have a legitimate business reason. If they refuse, that is their right, and you can decline to do business with them. If you need to verify their identity without asking them directly, use a licensed background check service that operates within the FCRA.

Services like Checkr, GoodHire, and Clarity (formerly Clear) are FCRA-compliant and can verify identity and run background checks with the person's consent. They do not reveal the SSN itself — they confirm the person's identity against public records, credit bureaus, and criminal databases. These services are used by employers, landlords, and lenders because they are legal and reliable.

If you are trying to locate someone, a licensed private investigator can do so legally using public records, property records, court documents, and other sources that do not require the SSN. This costs more than a website lookup but actually works and does not expose you to criminal liability.

What to do if you suspect someone's SSN has been stolen

If you believe your own Social Security number has been compromised, contact the Social Security Administration at 1-800-772-1213 or visit ssa.gov. You can also place a fraud alert with the three credit bureaus (Equifax, Experian, TransUnion) by calling 1-888-397-3742, which is the centralized fraud alert line. A fraud alert tells lenders to verify your identity before opening new accounts in your name.

Report the theft to the Federal Trade Commission at IdentityTheft.gov. The FTC maintains a database of identity theft reports and can help you create a recovery plan. If the theft has already resulted in fraudulent accounts or charges, file a police report and keep copies of everything — the report, credit bureau letters, and any correspondence with creditors.

If you suspect someone else's SSN has been stolen and misused, encourage them to take the same steps. You cannot file a report on their behalf, but you can provide them with the contact information and explain what happened.

Why you should never share your own SSN carelessly

The flip side of this issue is protecting your own number. Many organizations ask for your SSN out of habit, not necessity. Your doctor does not need it — they want it for billing purposes, but you can ask them to use a different identifier. Your car insurance company does not need it. Your utility company does not need it. Before you hand over your SSN, ask why they need it and whether you can use a different form of identification.

Legitimate organizations will have a reason ready. If they cannot explain why they need it or become defensive when you ask, that is a sign to take your business elsewhere. The fewer places that have your SSN, the smaller the window of exposure if one of them is breached.

Frequently Asked Questions

Can a private investigator find someone's Social Security number?

A licensed private investigator can locate someone using legal methods — public records, property records, court documents — but they cannot and should not attempt to obtain their SSN. If an investigator tells you they can get someone's SSN, they are either lying or planning to break the law. Hire one only if you need to locate someone, not to obtain their private information.

What if I need someone's SSN for a legitimate reason like employment?

Ask them directly. If they are explore for a job with you, they will provide it as part of the process. If you are lending them money or entering into a contract, request it on the form. There is no legal shortcut — you have to ask the person themselves.

Is it illegal to search for my own child's Social Security number online?

You should already have your child's SSN from when they were born or when you obtained it for tax purposes. If you have lost it, contact the Social Security Administration with proof of your relationship and they can help you. Searching for it through third-party websites is unnecessary and exposes your family's information to criminals.

What happens if I pay a website to find someone's SSN and it does not work?

You have lost your money and exposed your own identity. These sites rarely offer refunds, and disputing the charge with your credit card company can take weeks. More importantly, your payment information is now in the hands of people running an illegal operation. Monitor your accounts for fraud and consider placing a fraud alert on your credit file.

Can employers or landlords legally ask for my Social Security number?

Employers can ask for your SSN for tax and background check purposes — they need it to file your W-2. Landlords can ask for it to run a credit check, though some states limit when and how they can use it. You can ask why they need it, but refusing to provide it gives them legal grounds to deny you the job or apartment. If you are concerned about privacy, ask what they will do with the number and how they will protect it.
