How can I verify that my son's social has not been used to file on someone else's taxes?

I lost his card earlier in the year and I need to verify that it is not used.

Neither the IRS nor the Social Security Admin will provide that information directly, for security reasons.

The easiest way to find out is to e-file with his number.  If there has already been a return filed with that SSN your return will be rejected.  You will then have to PRINT and MAIL your return, and the IRS will sort out the problem.  In the meantime if your return is rejected you should contact the local police and report it as identity theft.
