Directory enquiries
When the Deutsche Bundespost had a monopoly on phone services, you used to ring 118 to find out a German phone number. Since decentralisation however, directory enquiries are provided by a wide range of companies, who charge very different prices for their services. Modern directory enquiries can supply you with more information than just a landline number. Depending on which provider you contact, you can also find out mobile phone numbers, fax numbers, postcodes and even names and addresses of anyone who has placed their details in the telephone directory. All of these companies have telephone numbers that start with 118, and you can find out more about their different services and tariffs by clicking here.

How to give and receive telephone numbers
German telephone numbers are usually said in pairs. This is not true however for the dialling code, so (0475) 24 88 79 would be given as null vier sieben fünf - vierundzwanzig achtundachtzig neunundsiebzig.
If there is an odd number of digits in a German phone number, the first digit is usually isolated and the followed digits are then spoken in pairs, for example 2 34 47 95.
