Replacing a Social Security Card for a Child

How to request a replacement Social Security card for a child, including the documents you need and where to apply.

Last updated: May 20, 2026Reading time: ~3 min

The short answer

Children can't use the online replacement service. A parent or legal guardian applies by mail or in person using Form SS-5, with proof of the child's identity, citizenship (if not on record), and proof of the parent's or guardian's relationship to the child.

Who applies

  • A parent or legal guardian generally applies on behalf of a child under 18.
  • You'll usually need to prove both your identity and the child's identity.

Documents you'll typically need

  • Child's identity: School ID, school record, medical record, passport, or adoption decree.
  • Child's citizenship: U.S. birth certificate or U.S. passport, if not already on record with SSA.
  • Your identity: A U.S. driver's license, state ID, or U.S. passport.
  • Custody / relationship: The child's birth certificate, court custody documents, or similar.

All documents must be originals or certified copies. SSA does not accept photocopies or notarized copies.

How to apply

  1. Download Form SS-5

    Get the form at ssa.gov/forms/ss-5.pdf.

  2. Fill it out

    Complete the form for the child. As the parent or guardian, sign on the child's behalf.

  3. Submit your documents

    Bring or mail the form and original documents to your local SSA office. Find an office at ssa.gov/locator.

  4. Wait for the card

    The replacement is free and arrives by mail. Processing times vary.

For a newborn

The easiest time to apply for a Social Security number for a new baby is at the hospital, when you give information for the birth certificate. If you didn't do that, you can apply later at a local SSA office.
