As part of the larger 02 geographic numbering zone, this code is assigned to fixed-line PSTN and VoIP services within the Goulburn exchange area.

Dialing Formats

The subscriber number is typically 8 digits long, with the first four digits (2388) identifying the exchange and the remaining four digits being the local line number.
Administrative and Regulatory Context
The Australian Communications and Media Authority (ACMA) administers the national numbering plan, and geographic numbers like 02 2388 are tied to a specific physical location. However, with the rise of VoIP and number portability, these numbers may be used by services not physically located in Goulburn, but they remain subject to the same regulatory framework. The code is not an overlay; it is a distinct exchange code within the 02 area, and local calls within the same charging zone may be billed as local calls, depending on the service provider's plans.
Caller Instructions

- International callers: Dial your country's exit code, then 61 2 2388 XXXX (no leading zero).
- Mobile callers within Australia: Dial the number as 02 2388 XXXX; it will be treated as a standard fixed-line call.
Typical Usage
This code is used by residential and business fixed-line services, including local government offices, small enterprises, and private subscribers in Goulburn and its surrounding suburbs. It is not associated with mobile services, which use separate non-geographic prefixes like 04xx. For businesses, having a geographic number can enhance local presence and trust, though many now opt for non-geographic numbers for national reach.
