|A "vanity" call sign is like a "vanity" automobile license plate. It is an Amateur call sign that, subject to availability, is personalized to the license holder's wishes. You must meet certain license class criteria in selecting your call sign and list the exact prefix, numeral and suffix for each selected call sign. You may select several call signs of the appropriate format and the first available one on your list will be assigned to you. Some call sign formats (1-by-2 and 2-by-1) are in short supply.
