Swiss vehicle registration plates start with a group of two letters, indicating the canton of registration (followed here by their main towns to aid location), or one letter for official vehicles.  [With thanks to Torsten Haemmerle]  Plates ending in U are dealer's plates; plates ending in Z are temporary imports; plates ending in V were rental vehicles (issue discontinued).
