It is a good idea to get the number when your child is born. You can apply for a Social Security number for your baby when you apply for your baby’s birth certificate. The state agency that issues birth certificates will share your child’s information with us. We will mail the Social Security card to you.

Or, you can wait and apply at any Social Security office. If you wait, you must provide evidence of your child’s age, identity and U.S. citizenship status, as well as proof of your identity. We must verify your child’s birth record, which can add up to 12 weeks to the time it takes to issue a card. To verify a birth record, Social Security will contact the office that issued it.

Anyone age 12 or older requesting an original Social Security number card must appear for an interview at a Social Security office, even if a parent or guardian will sign the application on the child's behalf.

Adoption: We can assign your adopted child a number before the adoption is complete, but you may want to wait. Then, you can apply for the number using your child’s new name. If you want to claim your child for tax purposes while the adoption is still pending, contact the Internal Revenue Service for Form W-7A, Application for Taxpayer Identification Number for Pending U.S. Adoptions. For more information, see Social Security Numbers For Children (Publication No. 05-10023).
