The fastest way to find your Social Security number

Your Social Security number appears on documents you already have at home. Check your Social Security card itself, your tax return (Form 1040), your W-2 from an employer, or your bank statements. If you have none of these, you can request a replacement card or a letter stating your number from the Social Security Administration.

The Social Security Administration (SSA) will mail you a replacement card at no cost if your card is lost, stolen, or damaged. You can request one online at ssa.gov, by phone at 1-800-772-1213, or in person at your local Social Security office. A replacement card typically arrives within 7 to 10 business days.

If you need your number before a card arrives, you can request a letter from SSA that states your number. This letter serves the same purpose as the card for most situations — banks, employers, and housing programs will accept it as proof. You can order this letter online through your my Social Security account, by phone, or by visiting an office in person.

Key Takeaways

  • Your Social Security number is printed on your Social Security card, tax returns, W-2 forms, and bank statements.
  • You can request a free replacement card or a letter with your number from the Social Security Administration if you cannot locate these documents.
  • Online requests through my Social Security account are the fastest method and require no office visit.
  • A replacement card arrives by mail in 7 to 10 business days; a letter with your number can be ordered the same way.

Documents that show your Social Security number

Start by looking through documents you have at home. Your original Social Security card has your number printed on the front. If you received a W-2 from an employer, your number appears in the upper left corner. Federal tax returns (Form 1040) show your number at the top. Bank statements, investment account statements, and retirement account statements also list your number.

If you have received correspondence from the Social Security Administration itself — such as a benefit statement, award letter, or notice — your number will be on that document. The same is true for Medicare cards, which display your Social Security number (though this is changing; new Medicare cards no longer include it).

Employer records are another source. If you are currently employed, your personnel file or pay stub may show your number. Former employers sometimes provide this information if you contact them, though they are not required to do so.

How to order a replacement Social Security card online

The fastest way to get a replacement card is through your my Social Security account at ssa.gov. You will need to create an account if you do not already have one. The account requires your Social Security number, date of birth, email address, and a U.S. mailing address.

Once logged in, select "Replace your Social Security card" from the menu. You will answer questions about your citizenship status, whether your name has changed, and why you need a replacement. The form takes about 10 minutes to complete. SSA will mail your card to the address you provide at no cost.

You can track the status of your card order through your my Social Security account. Most cards arrive within 7 to 10 business days, though this varies by location and mail volume. If you need your number before the card arrives, order a letter at the same time.

Requesting a letter with your Social Security number

A Social Security number verification letter serves the same purpose as a replacement card for most situations. Banks, employers, housing programs, and government agencies will accept it as proof of your number. You can order this letter through your my Social Security account, by phone, or in person.

To order online, log into your my Social Security account and select "Get a letter". The letter is generated immediately and you can print it right away. Some people print it the same day they order it. If you do not have an online account, call 1-800-772-1213 and a representative will mail you a letter within 5 to 7 business days.

In person, visit your local Social Security office with a photo ID and proof of address. An office staff member can print a letter on the spot. Bring a utility bill, lease, or bank statement as proof of address. You can find your local office at ssa.gov/locator.

What to bring if you visit a Social Security office in person

If you go to an SSA office to request a replacement card or letter, bring one form of photo identification and proof of citizenship. A driver's license, passport, or state ID card counts as photo identification. For citizenship, bring your birth certificate, passport, or naturalization papers.

You will also need proof of your current address. A utility bill, lease agreement, mortgage statement, or bank statement dated within the last 60 days works for this. If you do not have a current address on file with SSA, bring two documents showing your address.

Bring the original documents themselves, not copies. SSA staff will review them and return them to you. You do not need an appointment at most offices, but wait times vary. Call ahead or check ssa.gov to see current wait times at your local office.

If you have lost your Social Security card and need the number urgently

If you need your number before a replacement card or letter arrives, check the documents listed in the second section of this guide. Most people find their number on a tax return, W-2, or bank statement within minutes.

If you have no documents at home, call the Social Security Administration at 1-800-772-1213. A representative can verify your identity over the phone and provide your number verbally. This call is free. Have your date of birth, mother's maiden name, and current address ready.

For situations where you need written proof immediately — such as opening a bank account or starting a job — ask if the organization will accept a verbal confirmation from SSA. Some will. If not, a printed letter from your my Social Security account (if you have one) can be used the same day.

Frequently Asked Questions

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

No. The Social Security Administration requires you to create a my Social Security account to view your number online or order a letter. The account takes about 10 minutes to set up and requires your Social Security number, date of birth, email, and address. If you do not remember your number, call 1-800-772-1213 to speak with a representative.

How much does a replacement Social Security card cost?

Replacement cards and verification letters are free. The Social Security Administration does not charge for either. Be cautious of websites or services that claim to charge a fee for this — they are not affiliated with SSA and are not necessary.

What if I was born outside the United States?

You can still order a replacement card or letter through the same process. You will need to provide proof of citizenship or lawful permanent resident status. Acceptable documents include a passport, naturalization certificate, or green card. Call 1-800-772-1213 if you have questions about which documents SSA will accept.

How long does it take to get a replacement card by mail?

Most replacement cards arrive within 7 to 10 business days. Timing depends on mail volume and your location. You can track your order status through your my Social Security account. If you need your number sooner, order a verification letter at the same time — you can print it immediately from your account.

Can someone else request my Social Security card for me?

No. Only you can request a replacement card or letter through your my Social Security account. If you are unable to apply online, call 1-800-772-1213 and a representative will help you. A parent or guardian can apply on behalf of a minor child with proper documentation.
