↑ Prefixes for vehicle registration were introduced in 1906, but often changed due to the political changes after 1945. Vehicles were registered under the following prefixes: "I A" (1906– April 1945; devalidated on ngày 11 tháng 8 năm 1945); no prefix, only digits (since July till August 1945), "БГ" (=BG; 1945–1946, for cars, lorries and busses), "ГФ" (=GF; 1945–1946, for cars, lorries and busses), "БM" (=BM; 1945–1947, for motor bikes), "ГM" (=GM; 1945–1947, for motor bikes), "KB" (i.e.: Kommandatura of Berlin; for all of Berlin 1947–1948, continued for Tây Berlin until 1956), "GB" (i.e.: Greater Berlin, for Đông Berlin 1948–1953), "I" (for East Berlin, 1953–1990), "B" (for West Berlin as of ngày 1 tháng 7 năm 1956, continued for all of Berlin since 1990).
