Patti, I pulled this up from http://manual.ccbill.com/ (under the Webmaster Signup Page).

I've highlighted their requirement.

Basically, what i was told (where they say the principle must have an address in the same region) is that the principle must have a US address (it can by anywhere in the US) or an EU address (it can be in any country belonging to the EU). Otherwise, I need to appoint somebody (like a resident agent at companiesinc.com for instance) to act on my behalf. And, as I found out, that person gets listed as the primary on the accout, while I'm listed as something secondary (like the technical) and so that person would full control and authority over what happens to that account, including changing passwords, where checks, go, etc.
