Overview of Area Code 3943 (Eltham, VIC)
Area code 3943 is a geographic National Destination Code (NDC) within the Australian telephone numbering plan, specifically allocated to the Eltham region in the state of Victoria. Eltham is a suburb located approximately 20 kilometers northeast of Melbourne's central business district, within the local government area of the Shire of Nillumbik. The 3943 prefix serves the fixed-line PSTN and VoIP services for Eltham and its surrounding localities, including Research, Lower Plenty, and Montmorency.
In the international dialing format, the full number is written as +61 3 943x xxxx, where the leading '0' of the domestic trunk prefix is omitted. Domestically, callers within Australia must dial (03) 943x xxxx, while international callers should dial +61 3 943x xxxx.
Geographic Coverage and Local Dialing
The 3943 code is part of the larger Melbourne metropolitan area code 03, which covers a significant portion of Victoria. The specific 3943 prefix is assigned to the Eltham exchange, which provides local telephony services to residential and business customers in the area. As a geographic number, the tariff for calls to 3943 numbers is typically based on the caller's location, with local call rates applying for calls made within the extended Melbourne zone.
For local callers within the 03 region, dialing the eight-digit local number (943x xxxx) is sufficient. However, due to the widespread adoption of full national dialing, many callers now dial the full 10-digit number (03 943x xxxx) even for local calls, which is also valid.
Overlay and Number Portability
Currently, there is no overlay code for the 03 area, meaning that 3943 numbers are exclusively used for geographic fixed-line services. However, since the introduction of Local Number Portability (LNP) in Australia, customers can retain their 3943 number when switching service providers, including moving to VoIP or mobile services, though the number remains associated with the Eltham geographic area for routing purposes.
