Unfortunately, probably not. How do they know it was company letterhead?

Maybe some service akin to a credit check is required.

The listed contact may not be who ARIN [or other local RIR] thinks it is.
Since the RIRs contain the information required to answer those
questions, you'd expect them (or their data) to be involved in the
process of answering them.
They really don't. Thus far, when space is assigned, the RIRs have no way
to later authenticate that an organization using the space is the same one

2 of my 4 upstreams take whatever I put in the routing registry. The
other two require an email be sent requesting prefix filter updates. I
was just told by one, that they'll accept whatever I request, only
questioning it if someone complains to them about it. The other, I
haven't asked, but I assume they work similarly. On the bright side, all
of them are at least filtering.
