Where to find your Social Security number

Your Social Security number appears on several documents you likely already have at home. The easiest place to look is your Social Security card itself — the nine-digit number is printed in the middle. If you cannot find 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 and insurance documents often show it as well, usually with some digits masked for security.

If none of these documents are within reach, you can request a replacement Social Security card from the Social Security Administration (SSA). You will need to visit your local Social Security office in person with proof of identity, proof of citizenship, and proof of your current address. The SSA website has a field office locator tool where you can find the office nearest you and see their hours.

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.
  • You can create a my Social Security account online to view your number and earnings record without visiting an office.
  • If you have lost your card and cannot find your number anywhere else, you can request a replacement in person at your local Social Security office.
  • The Social Security Administration does not send unsolicited emails or texts asking you to verify your number — contact from SSA claiming to do so is a scam.

Creating a my Social Security account online

The fastest way to see your Social Security number and verify it is correct is to create a free account on the SSA's my Social Security website. You will need an email address, a phone number, and answers to security questions based on your credit history. The setup takes about 10 minutes and does not require you to visit an office or call anyone.

Once your account is active, you can view your Social Security number, check your earnings record to make sure employers reported your income correctly, and see an estimate of your future benefits. You can also use this account to request a replacement card or change your address on file with Social Security.

What to do if you think your number has been misused

If you see earnings on your Social Security record that you did not earn, or if you suspect someone else is using your number, contact Social Security directly. Call the national number at 1-800-772-1213 (TTY 1-800-325-0778) and speak with a representative. They can review your earnings record with you and help you report the issue.

You should also place a fraud alert with the three major credit bureaus — Equifax, Experian, and TransUnion — by contacting any one of them. A fraud alert tells lenders to verify your identity before opening new accounts in your name. You can also check your credit reports for free at annualcreditreport.com to look for accounts you did not open.

Protecting your Social Security number from scams

The Social Security Administration will never contact you by email, text message, or phone call asking you to verify or confirm your number. If you receive such a message, it is a scam. Do not click any links, read any files, or provide any information. Delete the message or hang up the phone.

Legitimate Social Security business happens in person at an office, through the mail, or through your my Social Security account. If you are unsure whether a contact is real, hang up and call the SSA directly at 1-800-772-1213 using the number on the back of your Social Security card or on the SSA's official website.

What documents you will need for a replacement card

If you need a new Social Security card, the SSA requires three types of documents: proof of identity, proof of citizenship, and proof of your current address. Proof of identity can be a driver's license, passport, or state ID card. Proof of citizenship can be your birth certificate, passport, or naturalization papers. Proof of address can be a utility bill, lease, mortgage statement, or bank statement dated within the last 12 months.

Bring the originals or certified copies — the SSA will not accept photocopies of most documents. You do not need to make an appointment at most offices, but you can call ahead to ask about wait times. The replacement card usually arrives in the mail within two weeks.

Frequently Asked Questions

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

No. The Social Security Administration does not release anyone's number to the public, and you cannot look up someone else's number through any official channel. If you need someone's number for a legitimate reason — such as adding a child to your insurance — ask them directly or request it through the organization that needs it.

What if I never received a Social Security number?

You can explore for one at your local Social Security office. Bring proof of age (birth certificate), proof of citizenship or legal residency, and proof of identity if you are 18 or older. Children under 18 can explore with a parent or guardian present. There is no fee.

Is it safe to share my Social Security number online?

Only share your number with organizations you trust and that have a legitimate reason to ask — such as your employer, bank, or the Social Security Administration itself. Never share it in response to an unsolicited email, text, or phone call, even if the message appears to come from a government agency.

How do I know if my Social Security number is correct?

Create a my Social Security account and log in to view your number. You can also call Social Security at 1-800-772-1213 and speak with a representative who will verify it for you over the phone after confirming your identity.
