Filing a trade name registers a business name for public record. A trade name is similar to a "doing business as" ("DBA") name, and is not legally required but is an acceptable business practice. A trade name does not grant exclusive rights to a business name, nor is a trade name similar to a corporation or limited liability company ("LLC"). If you want to file a corporation or LLC, you need to file with the Arizona Corporation Commission.
Filing a trademark registers a logo or slogan to be displayed on goods or services for public record. Trademarks also are referred to as service marks. These, too, are not required to be filed, but is an acceptable business practice.
