Siegburg and Meckenheim: registration for the Rhein-Sieg district
The Rhein-Sieg district surrounds Bonn and has two sites for registration and licences: Siegburg east of the Rhine and Meckenheim to the west.
Vehicles from Troisdorf, Sankt Augustin, Hennef, Bornheim, Königswinter and the rest of the 19 towns and municipalities of the Rhein-Sieg district are handled by the district’s road traffic office (Straßenverkehrsamt). The Federal Motor Transport Authority’s directory lists the main office in Siegburg, Kaiser-Wilhelm-Platz 1, and a branch in Meckenheim, Kalkofenstr. 2; it lists both as licensing offices too. The code issued is SU, for Siegkreis. BN appears for the district only as phased out, because Bonn is an independent city with its own registration office. With 380,586 cars on 1 January 2026, the district is one of the large ones, rank 6 of 398, and with 629 cars per 1,000 residents it has more than the national 592. Fees are the same at both sites: €30.00 for a used car in person, before plates and seals, as of October 2026.
