In the United States, there is no legal authority that grants coats-of-arms like one would find in some other countries, such as England, Scotland or South Africa. This being so, an organization is free to create and adopt a design of its choosing, which can then be registered with the federal government as a mark of the organization.

Any design is likely to be much more attractive, however, if some time is spent studying the basic rules of heraldry.
