Bund Philatelistischer Prüfer (the BPP, German for "Association of Philatelic Examiners") is the leading guild of philatelic examiners and expertisers in Germany. Although antecedents can be found earlier, the BPP was founded in December 1958. The BPP is a member of the Bund Deutscher Philatelisten (Confederation of German philatelists). Members of the BPP are stamp expertisers who have areas of expertise in which each is accredited (for example, a member may be accredited to only give opinions and certificates on stamps from a particular issuing entity or for only a period of history).
