“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.
The split/overlay information is not exhaustive. Older dates are removed.
