Replacement Card for a U.S. Born Child 
You can replace your child's Social Security card for free if it is lost or stolen. You are limited to three replacement cards in a year and 10 during a lifetime. Legal name changes and other exceptions do not count toward these limits. For example , changes in immigration status that require card updates may not count toward these limits. Also , you may not be affected by these limits if you can prove you need the card to prevent a significant hardship. Important You must present original documents or copies certified by the agency that issued them. We cannot accept photocopies or notarized copies. All documents must be current not expired. We cannot accept a receipt showing you applied for the document. 

What original documents do I need? 
Citizenship If you have not already established the child's U.S. citizenship with us , we need to see proof of U.S. citizenship. We can accept only certain documents as proof of U.S. citizenship. These include a U.S. birth certificate or U.S. passport. Important This documentation is only required if your child hasNOT already established citizenship with us. Identity Your child : While you can use a birth certificate to prove age or citizenship , you cannot use it as proof of identity. Social Security needs evidence that shows the child continues to exist beyond the date of birth. We can accept only certain documents as proof of your child's identity. An acceptable document must show your child's name, identifying information i.e., age, date of birth, or parents' names and preferably a recent photograph. We generally can accept a non - photo identity document if it has enough information to identify the child such as the child's name and age, date of birth or parents' names. We prefer to see the child's U.S. passport. If that document is not available , we may accept the child's : State Issued non - drivers identification card ; Adoption decree ; Doctor, clinic or hospital record ; Reli

user: Hello, i was told i would need some documents to prove my child's citizenship. Is that right?

assistant: That's right. If you haven't established the child's U.S citizenship, then you'll need to prove it to us.

user: Do you mean, i had to establish that time ago?

assistant: That's correct. If you didn't, then you need to provide a proof of the child's U.S citizenship. In that regard, we only accept certain documents in order to verify that, such as a U.S birth certificate or a U.S passport.

user: So, that documentation is something i must show to you if i hadn't done before.

assistant: That's correct. The procedure only apply if you didn't before.

assistant: By any case, you don't have the documentation?

user: Yeah, i don't have it right now.

assistant: Not a problem. we can accept other documents, such as a state issued non driver identification card or a Adoption decree, if that's the case.

user: To get the thing pretty clear. I only need the documentation if my child's citizenship has not been established yet, isn't?

assistant: Totally correct. Just necessary in that case.

user: And what about in case the card is stolen or lost?

assistant: If that happens, you can replace that card. be aware you only can do this three times in one year and ten times in your lifetime. But name changes and other exceptions do not count to these limits.
