德国电话号码

比较杂乱，位数不一
@wikipedia

Area codes in Germany (German Vorwahl) have two to five digits, not counting the leading zero. The leading zero must be dialed when calling from within Germany and must be omitted when calling from abroad. When calling via fixed networks within the same area, the area code is not required.

Mobile numbers are allocated area codes starting with 015, 016 and 017. The numbers have a total length of ten or eleven digits: Numbers starting with 017 or 016 are ten digits except 0176 and 01609 which are 11 digit like the numbers starting with 015. Since the advent of Mobile number portability, mobile phone number prefixes can no longer be relied on to determine the current operator of a particular mobile phone – only the original operator.
