Netherlands definitive stamps

Netherlands definitive stamps comprise regular postal issues produced for use across the postal region of the Kingdom of the Netherlands in Europe. The country's postal history began in 1852 with the release of its first adhesive stamps, which depicted King William III. Over the subsequent decades, the Dutch Post Office maintained postal operations through standard regular issues, including widespread numeral and portrait series that formed the basis for ordinary mail delivery.

The operational history of these definitives spans several key historical periods in the Netherlands. During the Second World War, the country was occupied by Germany, during which time stamp issues continued and semi-postal stamps were released. Following national liberation on 5 May 1945, previous stamps remained in use until a new series was introduced on 1 April 1946. This transitional series had originally been issued in Britain in 1944 by the Dutch Government in Exile for use on Dutch Navy vessels serving with the Allies. Since that time, postal services have maintained regular releases, including several long-running definitive stamp series, variable value stamps introduced in 1989, and specialized issues for the International Court of Justice in The Hague from 1934.

Definitive stamps from the Netherlands display varying design and production characteristics across different eras. Many issues prominently feature portraiture of the monarch or bold numeral designs. In addition to regular sheet formats, the Dutch Post Office has issued over 150 stamp booklets since their initial appearance in 1902. For the earliest issues from the reign of William III onwards, technical variations involving printing plates, perforations, and paper watermarks serve as the primary distinguishing features between printings.

Particular series can also be recognised by their subject matter, notably royal portraits starting with King William III or standard numeral motifs.
