📍 Geographic Location of Hobart
Geographic Overview
The Australian area code 3624 is a geographic National Destination Code (NDC) assigned to the city of Hobart, the capital of Tasmania. This code forms part of the broader 3-digit area code 3, which covers the entire island state of Tasmania. Specifically, the 3624 prefix is allocated to the central business district and surrounding inner suburbs of Hobart, including areas such as North Hobart, West Hobart, and Sandy Bay. As a geographic number, it is tied to the physical location of the fixed-line telephone service, typically provided via PSTN or fixed VoIP.
Dialing Formats
For callers within Australia, the number is dialed in the national format: 03 624X XXXX (where X represents the subscriber's unique digits). The leading '0' is the trunk prefix used for domestic calls. For international callers, the number must be dialed using the country code and without the trunk prefix: +61 3 624X XXXX. For example, a local Hobart number might be +61 3 6245 6789. When dialing from within Hobart itself, the full national number (including the area code) is still required, as Australia uses a closed numbering plan.
Administrative and Regulatory Details
The allocation of geographic numbers in Australia is managed by the Australian Communications and Media Authority (ACMA). The 3624 prefix is part of the Tasmanian numbering region, which is administered under the national numbering plan. This code is not an overlay; it is the primary code for Hobart and has been in use since the introduction of the current 8-digit numbering scheme in the 1990s. There are no plans for an overlay in this region, as the current numbering capacity is sufficient.
Caller Instructions
For local callers within Australia, simply dial the 10-digit national number starting with 03. For international callers, replace the leading '0' with the Australian country code +61. Ensure you have the correct international exit code for your country (e.g., 00 from most European countries, 011 from the US/Canada). It is important to note that calls to 03 numbers from mobile phones are typically included in standard national call allowances, but charges may vary depending on your carrier and plan.
Usage and Services
Numbers with the 3624 prefix are primarily used for residential and business fixed-line services. They are also used by government offices, educational institutions, and healthcare facilities in the Hobart area. Due to number portability, a number with this prefix may be transferred to a different service provider or even used for VoIP services, but it remains geographically associated with Hobart for regulatory and emergency services purposes.
