Is it legal to laminate your Social Security card?
The Social Security Administration’s discourage the lamination of Social Security number (SSN) cards because lamination would prevent detection of certain security features. To deter potential fraud and misuse involving SSNs, Social Security currently issues SSN cards that are both counterfeit-resistant and tamper-resistant. (For example, the card contains a marbleized light blue security tint on the front, with the words "Social Security" in white; intaglio printing in some areas on the front of the card; and yellow, pink, and blue planchets--small discs--on both sides. ) Social Security cannot guarantee the validity of a laminated card. You may, however, cover the card with plastic or other material if the material could be removed without damaging the card.
Social Security recommends that as a security precaution, you carry your Social Security card only when you expect to need it, for example, to show to an employer or other third party. Otherwise, you should keep your card in a safe place (e.g., at home with your important papers or in a safe deposit box).
