Geographic Overview
The Australian area code +61 8620 is a geographic numbering allocation serving the City of Wanneroo, a local government area in the northern metropolitan region of Perth, Western Australia. This code falls within the broader 8xxx range assigned to the Perth metropolitan area, with specific prefixes allocated to individual exchanges or exchange clusters.

Dialing Formats

Internationally, callers must use the country code and drop the trunk prefix, resulting in +61 8 8620 XXXX. The full national significant number is 9 digits (including the area code '8' but excluding the trunk prefix), and the local subscriber number is 8 digits (8620 XXXX).
Caller Instructions
- Local callers (within Australia): Dial 08 8620 XXXX. This applies to both fixed and mobile calls.
- International callers: Dial your country's exit code (e.g., 011 from the US/Canada, 00 from most other countries), then 61 8 8620 XXXX.
Overlay and Numbering Considerations
The 8 area code covers the entire Perth metropolitan area, including Wanneroo, and does not currently have an overlay code; all numbers within the region share the same area code. However, due to the growth of VoIP and mobile services, geographic numbers like +61 8620 are increasingly used for non-geographic purposes, but the numbering plan still identifies them as fixed-line services. When dialing, always include the area code even for local calls, as this is mandatory in Australia.
Regulatory and Technical Notes
The allocation of +61 8620 is managed by the Australian Communications and Media Authority (ACMA) and is assigned to licensed carriers. Number portability allows customers to retain their number when changing service providers, but the geographic association remains with the original exchange. For businesses, using a local number like +61 8620 can enhance local presence and trust, especially when serving the Wanneroo community.
