What type of mail is designated specifically for government business?

Official Mail is specifically designated for government business to ensure that correspondence related to governmental activities receives the necessary level of security and proper handling. This category of mail is used by government agencies to communicate with each other and with citizens, facilitating official communication that often pertains to important or sensitive matters.

Using Official Mail signifies that the correspondence is part of an official function of a governmental agency, ensuring it is processed, tracked, and delivered in accordance with regulations that govern governmental communications. Other types of mail, such as Certified Mail, Priority Mail, and First-Class Mail, are general mailing options that do not carry the same designation or specific regulations for government-related correspondence.
