📍 Geographic Location of Perth
Overview of +61 8624
The Australian telephone number range +61 8624 is a geographic allocation within the Perth Numbering Plan Area (NPA), governed by the Australian Communications and Media Authority (ACMA) under the national numbering scheme. This prefix corresponds to the National Destination Code (NDC) 8, which designates Western Australia, followed by the local exchange area code 624. The full subscriber number is structured as +61 8 624X XXXX, where the leading '6' after the NDC is part of the local number.
Geographically, +61 8624 numbers are assigned to landline services in the Perth metropolitan region, specifically covering central business districts and surrounding suburbs. The area code 8 is one of Australia's largest geographic NDCs, spanning the entire state of Western Australia, but the 8624 range is concentrated in the state capital, Perth. This includes localities such as Perth CBD, Northbridge, East Perth, West Perth, and adjacent neighborhoods. The administrative jurisdiction is the City of Perth and the broader Western Australian government.
Dialing Formats and Instructions
For local callers within Australia, the number is dialed as (08) 8624 XXXX using the national significant number format. The leading '0' is the trunk prefix used for domestic calls. For international callers, the number is dialed as +61 8 8624 XXXX, omitting the leading '0'. For example, a number in this range might be +61 8 8624 1234.
When calling from a mobile phone in Australia, it is standard practice to include the area code even for local calls, as mobile numbers are non-geographic and require full national dialing. For callers from overseas, the plus sign (+) represents the international access prefix, which varies by country (e.g., 011 from the US, 00 from most European countries).
Overlay and Number Portability
The Perth region has not implemented an overlay code; the 8 NDC remains the sole geographic code for Western Australia. However, number portability allows subscribers to retain their 8624 numbers when changing service providers, including moving to VoIP or mobile services, though the number's geographic association remains for routing purposes.
These numbers are primarily used for fixed-line PSTN and VoIP services, supporting both voice and fax. Businesses and residents in Perth often use these numbers for local presence, and callers should be aware that calls to 8624 numbers are typically charged at standard local rates, depending on their own telephone plan.
