What is the federal identifacation number of aetna ins ?

[xmasbaby0]

We do not have a way to find that for you.   What are you trying to do?   Do you have some sort of document from Aetna to enter?   What is it?

If you have a need for the FEIN of Aetna, then it will already be on whatever tax reporting document they sent you. It's generally in the format XX-XXXXXXX

if it's needed for tax reporting Aetna's EIN should be on the document you have.

Tax ID number is the same as an EIN (employer identification number) and I found this on their website...
