Free EIN / Tax ID Search

I was looking online for a free EIN / Tax ID search and kept coming up with paid results.  There are 2 problems with paid results.

1. It's not free
2. It's not the government's web site, so it's likely not accurate for newer businesses

The solution is to get it directly from IRS.gov here: http://www.irs.gov/app/ePostcard/

Another great benefit here is that you can link directly to a search via the search results URL: http://www.irs.gov/app/ePostcard/search.do?nameSearchTypeStarts=false&names=&nameSearchTypeAll=false&city=&state=All...&country=US&ein1=11&ein2=1111111&dispatchMethod=search&submitName=Search

Simply replace the EIN1 and EIN2 variables in the URL from 1's to whatever the Tax ID is that you're looking up.
