If you do not get the full name, address and EIN from the employer then you can use the wage transcripts for the infomation to complete the tax return HOWEVER you will have to mail in the return and attach those transcripts to the form 1040. You will NOT be able to efile the return AND you will simply need to ignore the error messages for the missing/incorrect information you do or do not enter.
FYI ... if you need to file a state return those federal transcripts don't have any state information on them .... so back to the employer or the SS administration to get a proper copy of the W-2 form.
