Capitalization

Many postal terms, especially those naming specific products, systems, and equipment, tend to be written as fully capitalized proper nouns in official communications, such as directives, news releases, management letters, and memoranda. Capitalization also occurs for terms that name specific committees, offices, projects, programs, and trademarked or registered items and brands. Likewise, general terms combined with a capitalized qualifier such as a personal or place name or an administrative designation are capitalized (e.g., Postmaster Smith, Miami International Service Center, Eastern Area). Some terms are simply capitalized to distinguish them from an otherwise general term, such as Headquarters and the Material Distribution Center.
