Area code zones in Germany

The telephone numbering plan of Germany is an open numbering plan, with a variable number of digits in the area code (German: Vorwahl) as well as in the subscribers' directory telephone number. Area codes in Germany have two to five digits. The prefix digit 0 (trunk prefix) must be dialed when calling between numbering plan areas within Germany. When calling via fixed-line networks within the same area, the area code is not required. In general, shorter area codes are assigned to larger cities, and longer area codes to smaller localities. Subscriber telephone numbers are usually inversely in size: those in larger cities have seven or eight digits, while those in smaller places may have as few as three digits. Area codes are grouped into eight geographic dialing regions determined by the first digit (2–9). Area codes beginning with 2 are found in the west, those with 3 in the east, those with 4 in the north, those with 5 in the north central part, those with 6 in the south-central part, those with 7 in the southwest, those with 8 in the south, and the 9s are found in the southeast.

Prefixes starting with 1 are special numbers, such as mobile telephones (15, 16, 17), shared-cost services (180), televoting numbers (13), and 10 for dial-around services. The former codes of 130 for freephone numbers and 190 for premium-rate numbers are moved to 800 and 900 to meet international standards. 700 is used for personal national phone numbers.

The ITU country code in the E.164 international numbering plan is 49. Outgoing calls to international destinations are dialed with the prefix 00, followed by the destination country code, area code, and telephone number.
