How do Replace a worn out social security card?

You can replace your Social Security card for free if it is lost or stolen. However, you may not need to get a replacement card. Knowing your Social Security number is what is important.

Keep your Social Security card in a safe place with your other important papers. Do not carry it with you.

If you choose to get a new Social Security card, see this page :

You are limited to three replacement cards in a year and 10 during your lifetime. Legal name changes and other exceptions do not count toward these limits.

Hi have a social security card already. However, my status changed recently from Green Card holder to US Citizen. Do I need to do anything with social security office? My current zip code is 19103.


To change your citizenship status :

  • Complete an Application For A Social Security Card (Form SS-5); and
  • Show us documents proving your:
    • New or revised citizenship status (Only certain documents can be accepted as proof of citizenship). These include your U.S. passport, a Certificate of Naturalization or a Certificate of Citizenship. If you are not a U.S. citizen, Social Security will ask to see your current immigration documents;
    • Age; and
    • Identity.
