Where to find your Social Security number

Your Social Security number appears on several documents you likely already have at home. The fastest way to find it is to look at your Social Security card itself — the nine-digit number is printed in the center. If you cannot locate the card, check your tax return (Form 1040), your W-2 from an employer, or any 1099 form you received for income. Your bank statements, insurance policies, and retirement account statements also show your number.

If none of these documents are available, you can request a replacement Social Security card from the Social Security Administration. You will need to visit your local Social Security office in person or apply online through ssa.gov if your state participates in the online application program. Bring a photo ID, proof of citizenship (birth certificate or passport), and proof of your current address (utility bill or lease). Processing takes about two weeks.

Key Takeaways

  • Your Social Security number is printed on your Social Security card and appears on tax forms, W-2s, bank statements, and insurance documents.
  • If you cannot find your number anywhere, you can request a replacement card from the Social Security Administration in person or online.
  • The Social Security Administration website (ssa.gov) lets you create an account to view your earnings record and verify your number without visiting an office.
  • Never share your Social Security number by email, phone, or text unless you initiated contact with a known organization.
  • If you suspect your number has been stolen, contact the Social Security Administration and place a fraud alert with the three major credit bureaus.

Verifying your number through your Social Security account

The Social Security Administration offers a free online account at ssa.gov where you can view your earnings record and confirm your number without leaving home. To create an account, go to ssa.gov/myaccount and click "Create an account." You will need to provide your name, date of birth, email address, and phone number. The system will ask you security questions based on your credit history to verify your identity.

Once your account is set up, you can log in anytime to see your Social Security number, your earnings history, and an estimate of your future benefits. This account also shows you if anyone has used your number to work or claim benefits under a false identity — a sign of Social Security number theft. You can print or download your information directly from the site.

What to do if you cannot remember your number

If you have lost or forgotten your Social Security number and do not have access to documents that show it, the Social Security Administration can look it up for you. Call 1-800-772-1213 (TTY 1-800-325-0778) during business hours, Monday through Friday, 7 a.m. to 7 p.m. Have your name, date of birth, and place of birth ready. You may be asked additional questions to confirm your identity over the phone.

Alternatively, visit your local Social Security office in person. Bring a photo ID and proof of citizenship. Staff can confirm your number on the spot. To find your nearest office, use the office locator tool on ssa.gov or call the main number above.

Protecting your Social Security number after you find it

Once you have located or confirmed your Social Security number, treat it as sensitive information. Do not carry your Social Security card in your wallet or purse — store it in a safe place at home, such as a locked drawer or safe. Write it down only when necessary, and never photograph it or email it to yourself.

Be cautious about who you give your number to. Legitimate organizations like banks, employers, and government agencies will ask for it, but scammers also pose as these entities. Never provide your Social Security number in response to an unsolicited phone call, email, or text message. If someone claims to be from the Social Security Administration, hang up and call 1-800-772-1213 yourself to verify.

Signs your Social Security number may have been stolen

Watch for warning signs that your number is being misused. These include receiving tax documents (W-2s or 1099s) from employers you do not work for, seeing earnings on your Social Security account that you did not earn, or receiving notices from the Social Security Administration about benefits you did not claim. You may also notice fraudulent accounts or inquiries on your credit report.

If you suspect theft, contact the Social Security Administration immediately at 1-800-772-1213. Report the fraud and ask them to flag your account. Then contact the three major credit bureaus — Equifax, Experian, and TransUnion — to place a fraud alert on your credit file. This alert tells lenders to verify your identity before opening new accounts in your name. You can also request a free credit report from annualcreditreport.com to check for unauthorized accounts.

Frequently Asked Questions

Can I check my Social Security number online without creating an account?

No. The Social Security Administration requires you to create and log into an account at ssa.gov/myaccount to view your number and earnings record online. This protects your information by ensuring only you can access it. Creating an account takes about 10 minutes and requires identity verification through security questions.

What if I lost my Social Security card and need a replacement?

You can request a replacement card online through ssa.gov if your state offers online applications, or visit your local Social Security office in person. Bring a photo ID, proof of citizenship, and proof of your address. There is no fee for a replacement card, and processing typically takes about two weeks.

Is it safe to look up my Social Security number on my own?

Yes, looking up your own number through official channels is safe. Use ssa.gov or call 1-800-772-1213 directly. Never use third-party websites that claim to look up Social Security numbers for you — these are often scams designed to steal your information or charge you for free information.

What should I do if I see someone else's Social Security number?

Do not use it or share it. If you found it on a document, destroy the document or return it to its owner. If you found it online or suspect it was posted without permission, you can report it to the website where you found it or to the Federal Trade Commission at reportfraud.ftc.gov.
