Interesting fact:

"The Intelligence Reform and Terrorism Prevention Act (IRTPA) of 2004 (Public Law (P.L.) 108-458) placed limits on the number of replacement Social Security cards an individual can receive. Beginning with cards issued on or after December 17, 2005, individuals may only receive three Social Security cards per year and 10 in a lifetime, with certain exceptions, such as correcting errors or name changes."
