i responded to a thread about a taxpayer having issues with her a w-2 she got. I informed her to contact the Social Security Administration. The problem was the w-2 was never sent to the SSA but she got her copy. It's the SSA that's supposed to get the W-2s and forward the info on to the IRS. Therefore I suggest you contact the SSA to see if their records match your w-2.
the alternative is to register on the IRS website and review your w-2 transcript but it's likely not to match otherwise there would be no issue with the iRS.
