A Social Security card is a document issued by the U.S. Social Security Administration that displays your nine-digit Social Security number

The card itself is a small plastic or laminated paper document, roughly the size of a credit card. It shows your name, your Social Security number, and your signature (on newer versions). The Social Security Administration issues it to U.S. citizens, permanent residents, and certain other people authorized to work in the United States.

The card serves as proof of your Social Security number, which is the identifier the government uses to track your earnings, taxes, and benefits throughout your life. You do not need the physical card to work or receive benefits — employers and government agencies can verify your number without it — but having the card makes it easier to prove your number when you need to.

Key Takeaways

  • A Social Security card displays your nine-digit Social Security number and is issued by the Social Security Administration to people authorized to work or live in the United States.
  • Your Social Security number tracks your earnings record, tax payments, and may be able to access for benefits like retirement, disability, and survivor benefits.
  • You can request a replacement card if yours is lost, stolen, or damaged, and the Social Security Administration issues it free of charge.
  • The card is not required to work or receive benefits, but it is the standard proof of your Social Security number when you need to verify it.
  • Protecting your card and number from theft is important because someone with your number can commit identity fraud or access your earnings record.

What information appears on your card

The front of the card shows your full name as it appears in Social Security Administration records, your nine-digit Social Security number, and your signature (on cards issued after 2000). The back is blank on most cards.

Older cards, issued before 2000, may not have a signature line. Cards issued to people not yet authorized to work show the words "NOT VALID FOR EMPLOYMENT" on the front. If you received a card as a child before you were old enough to work, you may have one with that restriction, and you can request a replacement card without it once you turn 16 or are authorized to work.

Who gets a Social Security card

The Social Security Administration issues cards to U.S. citizens, lawful permanent residents (green card holders), and certain other people with work authorization. You typically receive your first card when you are born or when you first enter the country with authorization to work or live here.

If you are not yet a citizen or permanent resident but have a work permit (such as an Employment Authorization Document), you may be able to request a Social Security number and card. The rules vary depending on your immigration status. You can contact the Social Security Administration directly or visit your local Social Security office to learn what documents you need to bring.

How your Social Security number is used

Your Social Security number is the key identifier in your earnings record. When you work, your employer reports your wages to the Social Security Administration using your number. This record determines how much you will receive in retirement benefits, disability benefits, or survivor benefits if you die.

The number is also used by the Internal Revenue Service to match your tax returns to your earnings record, by banks and lenders to check your credit history, by government agencies to administer benefits programs, and by healthcare providers to identify your medical records. Because your number is tied to so much of your financial and legal identity, protecting it from theft is important.

Replacing a lost, stolen, or damaged card

If your card is lost, stolen, or too damaged to read, you can request a replacement from the Social Security Administration at no cost. You will need to provide proof of your identity, proof of citizenship or work authorization, and proof of your age. Acceptable documents include a driver's license, passport, birth certificate, or state ID card.

You can apply for a replacement card in person at your local Social Security office, by mail, or online through the Social Security Administration's website (ssa.gov). If you apply online, you must have a driver's license or state ID card issued by your state. Processing time is usually two to four weeks if you apply in person or online, and longer if you apply by mail.

Protecting your card and number from fraud

Someone who has your Social Security number can open credit accounts in your name, file false tax returns, or claim benefits you are not may have access to to. You should not carry your card in your wallet or purse unless you need it that day. Keep it in a safe place at home, such as a locked drawer or safe.

Do not give your Social Security number to anyone who calls or emails you unsolicited. Legitimate businesses and government agencies will not ask for your number by phone or email unless you initiated contact. If you suspect your number has been stolen, you can place a fraud alert on your credit report by contacting one of the three major credit bureaus (Equifax, Experian, or TransUnion), and you can report the theft to the Social Security Administration.

Frequently Asked Questions

Do I need my physical card to work?

No. Your employer can verify your Social Security number through the Social Security Administration's system without seeing the card. However, you will need to provide your number to your employer, and having the card makes it easier to read the number correctly.

What do I do if my card was stolen?

Contact the Social Security Administration to report the theft and request a replacement card. You should also place a fraud alert on your credit report by calling one of the three major credit bureaus. Monitor your credit report for unauthorized accounts opened in your name.

Can I get a new card if my name changed?

Yes. If you changed your name due to marriage, divorce, or court order, you can request a new card showing your updated name. Bring your Social Security card, proof of citizenship or work authorization, and a document showing your name change, such as a marriage certificate or court order.

How long does it take to get a replacement card?

If you apply in person at a Social Security office or online, processing usually takes two to four weeks. If you apply by mail, it may take longer. You can check the status of your application on the Social Security Administration's website or by calling their customer service line.

What if I lost my card and need to work right away?

You do not need the physical card to start working. Provide your Social Security number to your employer, and they can verify it through the Social Security Administration's system. You can request a replacement card while you are working, and it will arrive by mail once it is processed.
