Burundi Area Country Phone Code
+257
How to dial a phone number in Burundi?
From outside Burundi, a caller would dial their international call prefix (typically 00 in Europe and 011 in North America), followed by 257 (the country code for Burundi), then the 2-3 digit area code of the place you're calling minus the trunk code '0', and finally the local number minus the trunk code '0'.
