The Italian Philatelic Press Association (also (Unione Stampa Filatelica Italiana or USFI) is a group of Italian journalists, writers and other professionals dedicated to philately. The first general meeting of USFI was held on 8 May 1966 in Italy. In 2006, Italy, Vatican City, San Marino and the Sovereign Military Order of Malta issued commemorative stamps in honor of the 40th anniversary of the association.
