📍 Geographic Location of Brisbane
Geographic Allocation and Coverage
The Australian telephone numbering plan, administered by the Australian Communications and Media Authority (ACMA), designates the prefix +61 7 323 as a geographic number within the National Destination Code (NDC) 07, which serves the state of Queensland. More specifically, the exchange block +61 7 323 is allocated to the central business district (CBD) and inner northern suburbs of Brisbane, the state capital. This block is part of the broader (07) 3xxx xxxx range that historically served the Brisbane metropolitan area. Suburbs covered by this prefix include Brisbane City, Fortitude Valley, Newstead, Bowen Hills, Spring Hill, and Herston. The area is a major commercial and administrative hub, hosting government offices, corporate headquarters, and cultural institutions.
Dialing Formats and Procedures
For callers within Australia, the number is dialed in its national format: (07) 323x xxxx. The leading 0 is the trunk prefix used to access the national PSTN. For international callers, the number must be dialed as +61 7 323x xxxx, omitting the trunk prefix. For example, a local Brisbane number might be (07) 3234 5678, which internationally is +61 7 3234 5678. When dialing from a mobile phone within Australia, the same national format applies, and the call is routed as a standard geographic call, not a mobile call.
Numbering and Overlay Considerations
Each geographic number in this range is a standard 10-digit national significant number (NSN) when including the trunk prefix, or 8 digits after the NDC. The numbering plan does not currently impose overlay codes for the Brisbane CBD; the (07) NDC remains the sole area code for the entire state of Queensland. However, number portability allows subscribers to retain their numbers when moving to a different service provider, but the geographic significance of the prefix remains tied to the original exchange location. This means that a number with the 323 prefix may be used by a business that has relocated, but the number still identifies as a Brisbane CBD line.
Caller Instructions and Practical Notes
For local callers within Brisbane, dialing the 8-digit local number (323x xxxx) is sufficient if the call originates from within the (07) area. For callers outside Queensland but within Australia, the full national number (07) 323x xxxx must be used. International callers should use the international format +61 7 323x xxxx. It is important to note that calls to this prefix are typically charged as standard fixed-line rates, depending on the caller's plan. Businesses and residents in this area may also use VoIP services, but the number remains a geographic number and is subject to the same dialing rules.
