+**Dial-in availability**
+Some phone providers may reject calls to this dial-in number because of its length.
-**Please note:** Dial-in from networks of some telephone providers does not work because the number is too long.
+Under the ITU’s E.164 recommendation, German phone numbers are generally limited to 13 digits, excluding the country code (+49) and the domestic dialing prefix (0). Providers handle longer numbers differently, so the simplest way to check is to try calling from the line you plan to use.
-According to a recommendation of the International Telecommunication Union, telephone numbers in Germany can be up to 13 digits long. Some providers stick strictly to the rules, others are flexible. In this case, the only thing that helps is to try it out.
