Area Code 2947 – Terrey Hills

Overview of Area Code +61 2 947

The +61 2 947 prefix is a geographic allocation within the Australian numbering plan, specifically assigned to the Terrey Hills exchange area in New South Wales. Terrey Hills is a suburb in the Northern Beaches region of Sydney, located approximately 20 kilometers north of the central business district. This prefix falls under the broader 02 National Destination Code (NDC), which covers New South Wales and the Australian Capital Territory. The 947 prefix is part of the local exchange serving Terrey Hills and its immediate surroundings, including parts of Belrose, Duffys Forest, and Frenchs Forest.

Dialing Formats and Caller Instructions

For callers within Australia, the local dialing format is (02) 947X XXXX, where the full national significant number is 10 digits (including the leading trunk prefix '0'). For international callers, the correct format is +61 2 947X XXXX, omitting the leading '0' of the NDC. When dialing from overseas, you must replace the '+' with your country's international access code (e.g., 011 from the US or Canada, 00 from most European countries).

Geographic Coverage and Administrative Jurisdiction

Terrey Hills is located within the Northern Beaches Council local government area. The exchange serves a mix of residential, commercial, and rural properties, with a population density typical of Sydney's outer suburbs. The area is known for its bushland surroundings and proximity to Ku-ring-gai Chase National Park. The prefix 947 is one of several local exchange codes in the 02 NDC, and it is not an overlay code; rather, it is a unique exchange identifier within the Terrey Hills telephone exchange.

Numbering and Regulatory Context

As a geographic number, the 947 prefix is tied to a specific physical location, and the Australian Communications and Media Authority (ACMA) manages its allocation. Local number portability allows customers to retain their numbers when moving within the same exchange area, but the geographic nature of the prefix means that calls are routed based on the original exchange location. This is important for businesses that rely on local presence, as the number indicates a Terrey Hills or Northern Beaches location.

Practical Usage and Considerations

For local callers, dialing a 947 number from within the same region typically requires only the eight-digit local number (947X XXXX) if the call is within the same charging area. However, due to the widespread adoption of full national dialing, it is always safe to use the full 10-digit format. For businesses, having a 947 number can enhance local credibility and customer trust. It is also important to note that while VoIP services can be assigned geographic numbers, the physical location of the caller does not affect the routing of calls to a 947 number; the number is permanently associated with the Terrey Hills exchange.
