Household Diary Study: The Postal Service currently owns and operates 34,613 post office locations (including branches) throughout the U.S…. In spite of a declining frequency of visits over the past several years, the use of post offices for mailing services continues to dominate the mail service industry. Fifty two percent of all U.S. households patronize a post office at least once a month, while just 13 percent visit a private mailing company.
