The EIN is sometimes listed as the IRS Number. In
Mergent Online, the IRS Number is listed at the top of the company profile.
For public companies, you can also find the EIN (or IRS Number) printed on the first page of 10-Ks, 20-Fs and other SEC filings. You can find these on Mergent Online and LexisNexis Academic as well as for free on Edgar.
