How to dial a phone number in Viljandimaa Estonia?
From outside Estonia, a caller would dial their international call prefix (typically 00 in Europe and 011 in North America), followed by 372 (the country code for
Estonia), then 43 the 2-3 digit area code of the place you're calling (Viljandimaa) minus the trunk code '0', and finally the local number minus the trunk code '0'. All local telephone numbers dialled within Estonia must use the leading '0' and the area phone code, even when calling locally.
