Meter identification numbers: NMI, MIRN, DPI

Electricity and gas meter numbers help connect the right information to your account so you only pay for what you use.

National Meter Identifier (NMI)

Every connection to the national electricity network is given its own identification number - the National Meter Identifier (NMI). You'll need this number if you change your electricity retailer.

The NMI is used to:

  • identify your supply address
  • identify the meters and meter types at your connected address
  • make sure you're billed for the right amount of energy.

You'll find your 11-digit NMI under ‘Your electricity supply details’ on Page 2 of your electricity bill.

If you don't have a bill yet, you can get help finding your bill and set up how you receive your bills at Billing options.

Your NMI stays the same unless the location of your electricity network connection point changes. For example, if a building is demolished and a new meter is installed.

The NMI is associated with an electricity network connection point, so when you move you'll have a new NMI at your new location.

Meter Identification Reference Number (MIRN)

If you live in Victoria, Queensland and South Australia your gas meter number is called your Meter Identification Reference Number (MIRN).

Your MIRN can be found on Page 2 of your gas bill. It should also be on your gas meter. You can get help finding your bill and set up how you receive your bills at Billing options.

Delivery Point Identifier (DPI)

If you live in New South Wales, your gas meter number is called your Delivery Point Identifier (DPI). It can be found on Page 2 of your gas bill. You can get help finding your bill and set up how you receive your bills at Billing options.
