How to dial a phone number in Formosa Argentina?
From outside Argentina, a caller would dial their international call prefix (typically 00 in Europe and 011 in North America), followed by 54 (the country code for
Argentina), then 3717 the 2-3 digit area code of the place you're calling (Formosa) minus the trunk code '0', and finally the local number minus the trunk code '0'. All local telephone numbers dialled within Argentina must use the leading '0' and the area phone code, even when calling locally.
