[1] 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).

Starting in 1994, the certification procedure was registered with the Association of German Chambers of Industry and Commerce ("IHK").

[3] Since 2006, the BPP has expanded its cooperation with the corresponding Austrian (VÖB) and Swiss (SBPV) associations.

In 2008, the BPP issued a four-volume series on the history of German philatelic examination and expertising, which was awarded the winner's prize, and at the stamp exhibition "London 2010 International Stamp Exhibition" with a gold medal.
