What the City Association Means
Hamilton is within the broad 07 geographic numbering region.
The five codes identify broad numbering regions rather than precise cities, and the NAD register allocates smaller code blocks to specific Local Interconnect Calling Areas. Number portability and nomadic or IP-based services can separate a geographic number from the user’s current physical location. Code 03 spans both mainland South Island time and the Chatham Islands’ 45-minute offset.
