When the Federal Republic of Germany was formed the Deutsche Bundespost (German federal post office) became the governmental agency with the monopoly for postal services; the name was adopted in 1950, prior to that year, it was called "Deutsche Post". The issue of the FRG was released on September 7, 1949 (Scott #665-666). In 1961 the two-digit postal code was replaced with a four-digit code; this was replaced after the reunification.
