I believe I remember CMP forum added this requirement almost a year ago to its members before you could post to keep out spammers or fake posts.Probably the FBI looking for address to swat! They will call it a Treasonous insurrection.
"The CMP" if you have submitted your paperwork to be able to purchase from them would have all your info.
You can always go to their site and send them an email to verify. They are typically quick to respond.
