Looking at a state’s area codes can tell you quite a bit about how the area has grown. The North American Numbering Plan, which was devised in the 1940s, has to serve more than 20 countries in North America, including the United States and Canada. As the populations of participating areas grow, the North American Numbering Plan has to add area codes to keep up with increasing needs for phone numbers.
Florida got its first area code (305) in 1947, the same year that most states got their initial area codes. Unlike most states, though, Florida quickly needed a new one. By 1953, the state gained 813 to cover the Tampa area. Florida got yet another area code (904) in 1965. These developments reflect the increases in the state’s population.
Florida added a significant number of area codes during the 1990s. Between 1995 and 1999, it gained over half a dozen new area codes. This sudden increase shows more than a growing population; it also occurred because a lot of businesses were moving to Florida and required phone numbers. Of course, telephone companies were also preparing for the onslaught of cell phone numbers that would develop as mobile technology became more affordable.
