"I have now seen the 3rd case in the last 4 months in which a PR paid money to get an EIN. Two people paid $260 each, and one paid $245."
That's CRAZY -- the IRS gives out these EINs for free -- just go right to IRS.gov.
Look at the photo above. That's the IRS home page (IRS.gov).
The link to the page you need for getting an EIN for free is right on there as the third option down in the right-hand column. You just click the box says "Apply for an Employer ID Number" and that takes you to the page shown in the photo below.
The important thing is to go right to IRS.gov - if you search for "online EIN" or other variations on that idea, you'll probably wind up at one of the scam sites and may not realize it.
