You shouldn't publicly post your EIN on your web page. It is similar to a business SSN, while it is not truly private, there is more you can lose by having it publicly display then just redacting it all-together.

Non profit EINs are public knowledge. Perhaps they are non-profit?

No, all EIN's are public per se, but they are used as an SSN for getting credit, etc. They are on annual reports, sure but that requires some work vs just having it on the website.

There is zero risk for a nonprofit to publish their EIN widely. It's already on Guidestar and Charity Navigator and usually discoverable with a simple Google search.

There is also a ton of value. It makes people who donate more confident that their donations made through corporate gift matching or donor advised funds are going to the right place.
