I agree but From what I understand the process is much different for registered mail and requires certain personnel, keys, or record tracking at different points of its transportation process to ensure compliance
A person does not have to sign for certified mail, I ask who is the mail from if I do not know the person I do not sign it, NO law says that I have to sign for anything
I refuse to sing for any certified mail or Registered mail that I get without me knowing who it is from first, If I do not know the person I will not sign for it, NO law says that I have to sign for it
