state offices: The President uses the licence plate 0-1, the Chancellor uses 0-2, the Foreign Minister uses 0-3 and the First State Secretary of the Foreign Office (i.e. the deputy Foreign Minister) uses 0-4. The President of the Parliament uses 1-1. This reflects the fact that the Parliament's President is not part of the executive branch but still ranks higher in (symbolic) importance than the Chancellor. These vehicles are tax-exempt and need not to be insured since the German government acts as insurer. The military uses old style non-reflecting plates. The German flag is shown, instead of the blue EU strip. Military plates use the letter Y instead of a city code, as no German city has the initial Y. The Y is followed by a dash and a six-digit number (or five digits for motorcycles), for example Y-123 456. These vehicles are tax-exempt and need not to be insured since the German government acts as insurer. There is also no mandatory technical inspection required but the Armed Forces carry out a regular internal inspection on these vehicles similar to the official inspection.

In some , such as North Rhine-Westphalia, the state code is also used by the police. Some branches and institutions of the federal government use the abbreviations of their names instead of a city code. The (German Federal Agency for Technical Relief) uses its abbreviation THW, so the plates read THW-80000, for example. All numbers on THW plates start either with the digit 8 or 9. The (Federal Administration of Waterways and Navigation) uses BW followed by a digit identifying the region of the office (from 1=north to 7=south). Before the (German Federal Railways) and the (German Federal Mail) were privatised, they used the abbreviations DB and BP (e.g. DB-12345, BP-12345). The federal police uses the code BP for instead of a
