Filing Authorization and EIN

Is it a REQUIREMENT for the filing authorization to show the EIN? We've always put it on the form routinely along with the Plan name, number, and Plan Year, but I'm not sure if it is actually a requirement. Just curious...

I don't think so (hope not because our authorizations don't use it).

I'm pretty good at being very careful about setting things up...and then completely forgetting the details about how/why. 

Thanks Bird - I couldn't find (when looking fairly quickly) anything on the e-file information/FAQ's, 5500 instructions, etc., that indicated it was required. It's just been done that way here since, approximately, 300,000 B.C., give or take a few years, so I thought I'd check. Certainly doesn't cause any harm...

FWIW, we don't show the EIN on ours either.
