NANP Area Code History: 1946

When designers first went to the drawing board with a numbering system, this was their "first draft copy". While a few of the codes correspond to those today, this plan emphasized simplicity of assignment. Geographic areas (being assigned multiple NPAs) were assigned consecutive codes and some attention was paid to population. All of Canada being forced into the 900s, however, was not particularly popular and also left little room for expansion. This plan was later modified into what became the final assignments in October, 1947.

* - Canadian Maritime Provinces
RED - Unassigned for future use
GREEN - Part of the Original Assigned Codes
GRAY - To remain unassigned for local service use
