How to dial a phone number in Helsinki Finland?
From outside Finland, a caller would dial their international call prefix (typically 00 in Europe and 011 in North America), followed by 358 (the country code for
Finland), then 9 the 2-3 digit area code of the place you're calling (Helsinki) minus the trunk code '0', and finally the local number minus the trunk code '0'. All local telephone numbers dialled within Finland must use the leading '0' and the area phone code, even when calling locally.
