You cannot look up your Social Security number online through a public search tool

There is no website where you enter your name and birth date and receive your Social Security number back. The Social Security Administration does not publish a searchable database of numbers, and no legitimate third-party service can retrieve one for you. If you have lost track of your number, you will need to contact the SSA directly or check documents you already have.

This matters because scammers often claim they can find your number online for a fee, or that you can recover it through a website that looks official. These are fraud. Your Social Security number is sensitive information — the SSA protects it deliberately, and you should too.

Key Takeaways

  • Your Social Security number does not appear in any public online database; the SSA does not publish searchable records of numbers.
  • The fastest way to find your number is to check documents you already have: tax returns, W-2 forms, bank statements, or insurance papers.
  • If you have no documents, you can contact the SSA by phone at 1-800-772-1213 (TTY 1-800-325-0778) with proof of identity and citizenship.
  • Do not pay anyone claiming they can look up your number online, and do not enter your personal information into websites that promise to retrieve it.
  • The SSA's official website is ssa.gov; any other domain offering to find your number is not legitimate.

Check documents you already have first

Your Social Security number appears on many papers in your home. Start there before contacting the SSA, because you may find it within minutes. Look for a W-2 form from any employer, a 1099 form if you have been self-employed or received other income, or a tax return you filed yourself. All three show your number clearly.

Bank statements, investment account statements, and insurance policies (health, auto, home, or life) also print your number. If you have ever applied for a mortgage or car loan, the paperwork from that application will have it. Utility bills sometimes include it as well. Check a file folder or drawer where you keep financial documents.

If you have a Social Security card itself, the number is printed on the front. Many people keep theirs in a safe or safe deposit box rather than a wallet, so check there too.

Contact the Social Security Administration directly

If you cannot find your number in any document, call the SSA's main line at 1-800-772-1213. The line is open Monday through Friday, 7 a.m. to 7 p.m. Eastern time. If you are deaf or hard of hearing, use the TTY number 1-800-325-0778. Have your proof of identity ready — a driver's license, passport, or state ID card — because the SSA will ask for it before releasing your number.

You can also visit a local Social Security office in person. Find the office nearest you on ssa.gov by entering your zip code. Bring the same proof of identity. Walk-in hours vary by location, and some offices now require an appointment, so call ahead or check the office's page on the website.

The SSA may also ask for proof of citizenship or legal residency, such as a birth certificate, passport, or naturalization papers. If you do not have these with you, ask what documents they accept and whether you can mail them in instead of making a second trip.

Understand why your number is not searchable online

The SSA keeps Social Security numbers private by design. Your number is the key to your earnings record, your benefits, and your tax history. If anyone could search for it using your name and birth date, identity theft would be far easier. The agency deliberately does not publish a directory or allow searches, even for people trying to find their own numbers legitimately.

This is different from other government records. Property ownership, court cases, and business licenses are often public and searchable online. Social Security numbers are not, because the harm from exposure is too great. Treat this as a feature, not a barrier.

Recognize and avoid scams

Websites and emails claiming to retrieve your Social Security number for a fee are scams. So are calls from people saying they found your number and need payment to "secure" it or "verify" it. The SSA will never call you asking for money, and no legitimate service charges you to find your own number.

Be especially wary of sites that look like the official SSA website but have a slightly different web address. The real SSA website is ssa.gov only. Common fakes use addresses like "socialsecurityadmin.com" or "ssa-benefits.com". Check the full URL in your browser's address bar before entering any information.

If you receive a suspicious call or email claiming to be from the SSA, hang up or delete it. Then contact the SSA yourself using the phone number on your Social Security card or on ssa.gov. Do not use a number from the suspicious message.

What to do if you suspect your number has been misused

If you find that someone else has used your Social Security number — for example, you see accounts you did not open, or you receive tax documents for income you did not earn — contact the SSA's fraud hotline at 1-800-269-0271. You can also report it online at ssa.gov/fraud.

At the same time, place a fraud alert with the three major credit bureaus (Equifax, Experian, and TransUnion) and consider freezing your credit. These steps make it harder for someone to open new accounts in your name. The Federal Trade Commission's website at identitytheft.gov walks through the full process and provides templates for letters to send.

Frequently Asked Questions

Can I look up someone else's Social Security number?

No. The SSA will not release anyone's number except to that person, and only with proof of identity. If you need someone's number for a legitimate reason — for example, you are their employer and need it for tax forms — ask them directly. They can provide it or authorize the SSA to release it to you.

What if I lost my Social Security card?

You do not need to replace it immediately if you know your number. However, if you have lost the card and cannot remember the number, follow the steps above to retrieve it. You can then request a replacement card from the SSA if you want one. There is no fee for a replacement.

Is my Social Security number on my tax return?

Yes. Your Social Security number appears on every federal tax return you file, along with your spouse's if you file jointly. If you filed taxes in the past few years, a copy of that return will show your number. You can also request a transcript of your return from the IRS at irs.gov.

Can I change my Social Security number?

The SSA can issue a new number, but only in specific situations such as identity theft or domestic violence. A new number does not erase your old earnings record — the SSA links them together. Changing your number is not a solution to privacy concerns and is rarely done. Contact the SSA if you believe you have a genuine reason to request one.
