The USTA is the governing body for tennis in the United States. It is a member of the International Tennis Federation (ITF), which is the ultimate governing body for tennis worldwide. The USTA is comprised of 17 sections, each representing one or more states. Some of these sections have created districts that represent specific geographic areas within the section. Some umpire associations may require an annual fee while others have automatic membership without fees. All certified tennis officials must be members of the USTA. No additional membership fee is required to belong to the National USTA Officials Council, of which you will become a member once you are certified. Your USTA section might have an officials council you would need to join and a membership fee could be involved but these organizations vary from section to section.
