Geographic numbers in the New States were assigned area codes starting with 3, in some cases followed by the former East German area code (without the initial 0) or a code similar to it. Thus, Leipzig, for example, which had used East German domestic area code 41, was assigned the new area code 341 in the unified telephone system. On the other hand, some area codes were changed: for example, the small town of Zossen used to have East German area code 323, but the new area code is 3377. Area code 30, formerly used by West Berlin, was assigned to the entire reunified Berlin.
