Note: A "Region" is defined as a state (in the USA) or a province (in Canada) or a country (if outside of North America). Some regions have no abbreviation, e.g., the country Barbados, and they are listed at the beginning of this table as a region "--". A "Split" (in the "Description" column) is when an area code used to be the code in that entire region and that region is now divided into two (or more) different area codes BUT the region within that "split" area code no longer has the "old" area code number. An "Overlay" is when two (or more) area codes reside within the same defined region. If a region has multiple area codes, for example the province of Alberta (AB), the first of that region is displayed in color, e.g., "AB", and all other area codes in that same region have the region identifier in black, e.g., "AB".
