Check your bill first
Retailers must show the distributor's faults and emergencies number on every bill, so the network's name is almost always there. Look near the faults number or next to your National Meter Identifier (NMI), the 10 or 11 character number that identifies your connection. Our guide to reading your bill shows where to look.

Check by postcode
When you enter your postcode on Energy Made Easy or Victorian Energy Compare, the site shows plans for your network. Where a postcode is split between two networks, it asks you to choose, and your bill settles it. Your network can also confirm whether it supplies a particular address.
Why it matters
Prices differ more between networks than most people expect. The same retailer's cheapest plan can be hundreds of dollars a year apart in neighbouring networks. Once you know yours, see the cheapest plans in each network.
Common questions
Usually next to the faults and emergencies phone number, which retailers must include on every bill, or near your NMI. Some bills also name it in the supply details section.
Yes, near network boundaries. Postcodes and network areas do not line up exactly, which is why comparison sites sometimes ask you to choose your distributor.
No. The distributor is tied to the physical connection at your address. Switching retailer changes who bills you, not who owns the lines.
