Vanity Call Signs

Any licensed amateur radio operator may request a "vanity" call sign. This may be any available call sign as long as it is authorized both to the operator's geographical region and to the operator's license class. In general, a call sign must be unassigned for a minimum of 2 years before it is available for re-assignment.
