Telephone numbers in East Germany

Upon the division of Germany after World War II into West Germany and East Germany, telephone numbers in East Germany were administered independently from the telephone network in the west, despite their common telecommunication history.

East Germany was assigned telephone country code 37 by the International Telecommunication Union (ITU) by bilateral agreements in ITU Notification 980 of 10 March 1966.

Telephone calls between East and West Germany required international dialling with the international call routing prefix 00 and country code for calls from West Germany to East Germany, and 06 49 from East Germany to West Germany.
