After you receive your SSN, we advise you not to carry the Social Security Card with you, but to memorize the number or make a note of it elsewhere and put the card in a safe place with your other important documents. We all need to be careful to avoid identity theft. Don't lose your card! Replacement is tricky.
Replacing a Lost Social Security Card
The SSA will replace your card (and will give you the same number) only if you are currently eligible to get one. However, you may continue to use your Social Security number if you know it and your card is not requested.
Check the document requirements under the category for your current eligibility. The SSN application has a question asking if you have ever filed for or received an SSN card before.
