History & Background of Area Code 904
Area code 904 was introduced in 1965 after splitting from Florida's original 305 area code. Initially, it covered the entire northern half of Florida, stretching from the Atlantic coast to the Gulf Coast. As Florida's population and demand for telephone numbers increased, the 904 service area was gradually reduced through several geographic splits. Today, area codes 904 and 324 serve Northeast Florida together.
- 1947: Florida operated under a single area code, 305, when the North American Numbering Plan (NANP) was first introduced.
- 1965: Area code 904 was created from area code 305, becoming Florida's third area code and covering the entire northern portion of the state.
- 1995: Area code 352 was introduced, separating Gainesville, Ocala, and surrounding communities from the 904 region.
- 1997: The Florida Panhandle, including Tallahassee and Pensacola, moved to the newly created 850 area code.
- 2001: Area code 386 was created, transferring Daytona Beach and nearby communities out of the 904 service area and concentrating 904 around Jacksonville and the First Coast.
- February 26, 2024: Area code 324 was introduced as an overlay to 904, allowing both area codes to serve the same geographic region without requiring existing customers to change their phone numbers.
- Today: Area codes 904 and 324 operate together across Northeast Florida, serving Jacksonville, St. Augustine, Fernandina Beach, and surrounding communities. The region also celebrates "904 Day" each year on September 4 (9/04), recognizing Jacksonville's local identity and community pride.
