How to dial a phone number in Kasai-oriental Congo Democratic Republic?
From outside Congo Democratic Republic, a caller would dial their international call prefix (typically 00 in Europe and 011 in North America), followed by 243 (the country code for
Congo Democratic Republic), then 4 the 2-3 digit area code of the place you're calling (Kasai-oriental) minus the trunk code '0', and finally the local number minus the trunk code '0'. All local telephone numbers dialled within Congo Democratic Republic must use the leading '0' and the area phone code, even when calling locally.
