She would still need SS number. Can you contact SS office and tell them your wife have a job and the HR require to have a SS number. One can work for 3 months before HR inquire about SS number. Make a connection with store or restaurant folks and get a PT job letter from there, fax that report to the office- it’s emergency now . SS office are still doing non contact work and they are still open. If you get SS number, then ASAP file tax. If you filed for the year 2019 and it get accepted, you should be in the system and there would get 2900. I have not heard exact date when the next stimulus is coming! Have anyone?Since you are married, it’s a fraud to file ‘Non filer’ even after she got SS number.
