The numerical designator ‘904’ identifies a specific geographic region within the North American Numbering Plan (NANP). This three-digit code serves as a prefix for telephone numbers assigned to subscribers within a defined area, enabling the telecommunications network to route calls efficiently. For example, a valid phone number in this region would begin with 904, followed by a seven-digit local number.
Its implementation facilitated the growth of communication networks by providing a structured method for allocating telephone resources. The creation of this code allowed for efficient expansion and management of telephone services as populations and technological demands increased. Understanding its historical context reveals its role in supporting economic and social development within the designated region.
