<prompt> Human: On Saturday, I received a letter from the IRS saying my social security number may have been used to gain employment. Ive been employed at the same company for the last four or five years. The letter outlined what I need to do and I plan to take action later today, but I was wondering if anybody else had run into the same issue and what became of it.  <response>: My mother got this letter as well about three weeks ago. the IRS just told her that she doesnt need to take any action yet as they are looking into it. Would just keep an eye on your credit report as well just in case.
