Various combinations that could be considered politically unacceptable—mainly due to implications relating to Nazi Germany—are disallowed or otherwise avoided. The district Sächsische Schweiz uses the name of its main town, Pirna, in its code "PIR", to avoid the use of "SS", the name of the nazi group; similarly "SA" is also unused. This is why automobiles for the government and parliament in Saxony-Anhalt are registered with LSA (Land Sachsen Anhalt). In 2004 in Nuremberg, an automobile owner was refused a number plate beginning N-PD because of the connection to the political party, the NPD.
