* Indicates that daylight savings time is not observed.

"Split" refers to a service area served by one area code being subdivided into two or more areas, with the original area code serving one of the subdivisions and new areacode(s) serving the other(s).

"Overlay" refers to a service area being served by two or more area codes simultaneously. usually i write "X overlaid on Y" to mean that X is a new areacode that will service an area that previously was serviced solely by Y.

The advantage of a split is that for intra-service area dialing, only 7 digits are required, but some existing users will be forced to change their web site, stationery, business cards, etc. in contrast, an overlay only affects new customers, so is less of a burden; however, neighbors may have to dial 11 digits to call each other.

Unassigned area codes: Any area code listed as an unassigned area code is an invalid area code when it was last checked. If you're receiving a call from an unassigned area code, it is likely a telemarketer is spoofing the phone number, making it appear as if they are someone else and so the call is not blocked.
