I have the W2 transcript I received from IRS to process my back taxes because Iost my W2s for 2016. They sent redacted info regarding my Social Security Benefits statement and it shows the SSA-1099 Federal Identification Number (FIN) NOT EIN as xxxx4813. No one can seem to get me the full number. I even googled it. How do I obtain FIN for Social Security Administration. Apparently they have one because the IRS has the last 4 shown on the W2 transcript. Can anyone help
