There are no heraldic authorities in the U.S. so as such one doesn't need to register arms in the U.S. In the U.S. arms can be assumed and used. South Africa also does not require a registration of arms, one can assume their arms as well, but a registration with the bureau provides the armgier with a written record of their arms as well as the expertise of the bureau's office in designing arms that do not infringe upon someone else's.
