About 904 Area Code
Area code 904 serves Jacksonville and the First Coast region of northeastern Florida. Created in 1965 during a split from the original 305 area code that covered the entire state, 904 includes major population centers such as Jacksonville, St. Augustine and Fernandina Beach. The code extends across Duval, St. Johns, Nassau, Clay and Baker counties, supporting local voice and SMS-capable numbers used by businesses, healthcare providers, military installations and community organizations throughout coastal and inland communities.
The 904 region combines diverse economic drivers including logistics (JAXPORT, CSX railroads), financial services (Bank of America, JPMorgan Chase), healthcare (Mayo Clinic, Baptist Health), military operations (Naval Station Mayport, NAS Jacksonville) and tourism anchored by St. Augustine. Local businesses use 904 numbers for customer support, appointment scheduling, delivery coordination and service inquiries. Geographic numbers deliver stronger answer rates than toll-free alternatives because they signal local presence and community connection.

How Does Local 904 Phone Numbers Work?
