Find any 904- phone number in Florida
The 904 area code is one of the many area codes that make up the North American Numbering Plan (NANP). This numbering plan is used to assign area codes throughout the United States and Canada, with the 904 code specifically covering the north eastern region of Florida. It is the most populous area code in the state, covering much of Jacksonville and surrounding areas, as well as downtown Jacksonville, St. Augustine, Mandarin, and middleburg.
The 904 area code was put into effect in 1965 when the North American Numbering Plan (NANP) went into operation. The NANP was created in 1947 in order to simplify phone number formats and make it easier for callers to remember phone numbers by having a set pattern for each state or country. This system made it easier to assign area codes and to provide more local numbers for businesses and individuals to utilize. Areas codes are typically assigned in a way that results in equal population distribution across a given area, and as that population grows, additional area codes are added to keep the system functioning.
