You can get a replacement for free if you lose your card, but you may not need to get a replacement since knowing your social security number is what's important.
The easiest way to apply for a replacement is if you have an my Social Security account. Do you?
I don't.
Do you want to create one?
Not right now.
What if I can't get one of the required documents?
In that case, we'll ask you for another suitable document. The submitted documents must be current, not expired and show your name, identifying information, date of birth and, preferably, a recent photograph.
Is there a limit to how many times I can get a replacement card, and, are there exceptions to the limits?
yes, there are limits. You are limited to only 3 replacements a year and 10 replacement during your lifetime. There are exceptions like changes in immigration status, legal name changes or if you can prove that you need the replacement to prevent a significant hardship.
What if I haven't yet stablished my citizenship with you guys?
then you'll need to show us a proof of your U.S. citizenship. Documents like your birth certificate or your U.S. passport are the most common proof of citizenship received.
and as proof of identity?
