There are many references on prefixes. Some old and some new, but all may be of value. The ITU (International Telecommunications Union) headquartered in Geneva, Switzerland is the international organization within the United Nations System that is responsible for allocating call sign blocs. You can access their list of prefixes at http://www.itu.int/cgi-bin/htsh/glad/cga_callsign.sh?lng=E This is a list of the basic allocations from which the ham radio prefixes are derived. Virtually every prefix can be resolved by referring to this list.
