📍 Geographic Location of Burnie
Geographic Overview
The Australian area code 03 643 is a geographic National Destination Code (NDC) serving the city of Burnie and its surrounding regions on the northwest coast of Tasmania. Burnie is a major port city and the fourth-largest city in Tasmania, situated approximately 300 kilometers northwest of the state capital, Hobart. The code covers the Burnie City Council area, including suburbs such as Acton, Park Grove, Romaine, and Shorewell Park, as well as nearby towns like Somerset and Wynyard. This allocation is part of the broader 03 numbering plan, which encompasses the entire state of Tasmania and parts of Victoria, but the 643 prefix specifically identifies the Burnie exchange area.
Dialing Formats
For local callers within Australia, the number is dialed in its full national format: 03 643X XXXX (where X represents the subscriber digits). The leading '0' is the trunk prefix used for domestic calls. When calling from outside Australia, the international format must be used: +61 3 643X XXXX. The country code for Australia is +61, and the leading '0' of the national prefix is omitted. For example, a Burnie landline number might be 03 6434 5678 locally, or +61 3 6434 5678 internationally.
Caller Instructions
Australian callers should always include the area code when dialing Burnie numbers, even if calling from within the same region, as local number portability and mobile network integration make it mandatory. International callers should replace the '0' with the +61 country code. If you are using a mobile phone, you can simply enter +61 3 643X XXXX in international format. For landline calls from overseas, check with your provider for any additional international dialing prefixes.
