Numberway lists a variety of options to find a person or business in Germany, such as Das Telefonbuch, GoYellow and Gelbe Seiten. To find a local business in Germany use Das Örtlich.
Das Telefonbuch is the official phone book in Germany. To find a person or business, enter a name into the "wer/was" box. Optionally, a city may be entered in the "wo" box to narrow the search. Das Telefonbuch provides an autocomplete function that helps correct spelling.
GoYellow and Gelbe Seiten are the German business directories. Correct spelling is necessary when searching for a specific town or city and, unlike Das Telefonbuch, neither GoYellow or Gelbe Seiten have an autocomplete function.
