  Interesting to know
  After WW2 Germany got divided into East and West
  1964 when the international Direct Dialing System was established
  West Germany got the country code +49
  East Germany the country code +37
  
  After German Reunification following the fall of the Berlin wall
  1993 it was easy to integrate the former East German cities / villages
  into the West German Phone System.
  
  Even though reunification seamed most unlikely in the late 1960s
  when the German National Direct Dialing system became actif,
  an employee of Deutsche Bundespost,
  (former PTT englobing Post Serices, Telekom and Postbank)
  had blocked all numbers starting with 3
  (+49 311 was the area code for West Berlin)
