+// countries which have the concept of Area Code, the National (significant) Number contains the
+// area code. It contains a maximum number of digits which equal to 15 - n, where n is the number of
+// digits of the country code. Take note that National (significant) Number does not contain
+// National(trunk) prefix. Obviously, as a uint64, it will never contain any formatting (hypens,

+// In some countries, the national (significant) number starts with a "0" without this being a

+// There have been plans to migrate fixed-line numbers to start with the digit two since December
+// 2000, but it has not happened yet. See http://en.wikipedia.org/wiki/%2B39 for more details.
+//
+// This field can be safely ignored (there is no need to set it) for most countries. Some limited
+// amount of countries behave like Italy - for these cases, if the leading zero of a number would be
+// retained even when dialling internationally, set this flag to true.
