Step 1 — Where Is My NMI on My Bill?

Your electricity bill shows your NMI. Every retailer prints it somewhere on the bill, and the position differs between retailers.

Start on the first page. Look for a small block of account details near your account number.

Common section labels: "Your Details","Your Account Details", or "Your Electricity Supply Details".
Common field labels: "NMI","National Metering Identifier", or "National Meter Identifier".
Common positions: the top of the first page, or a details panel further down.
If the first page shows no NMI: read the meter details section on the later pages.

Bill layouts vary between retailers and change over time, so treat these labels as common patterns. For the other charges and codes on the same bill, see how to interpret your electricity bill.

Step 2 — Check the NMI Format: 10 or 11 Digits

An NMI is 10 or 11 digits long. When an NMI has 11 digits, the last digit is a check digit.

Length: 10 or 11 digits. Many bills print the first 10 digits only.
Most states: the NMI is numeric, for example 6200000000.
Queensland: some Queensland NMIs may start with two letters before the digits.
The meter number: a separate, shorter number printed on the same bill.

Step 3 — NMI Lookup in Your Retailer Portal or by Phone

If you have no paper bill to hand, sign in to your retailer account.

Sign in to your retailer website or mobile app.
Open the account, property, or meter details page.
Read the NMI from the supply details panel.
If the portal shows no NMI, telephone your retailer.
Give the operator your account number and your supply address.

Retailer portals differ, and some retailers show the NMI only on a past bill in your billing history. Check more than one page before you telephone.

Step 4 — Verify the NMI Number You Copied

A 10-digit or 11-digit number is easy to mis-type. Check every digit before you send the NMI to an installer or a retailer.

Read it twice: compare your copy against the bill, digit by digit.
Watch the letter O and the digit 0: most NMIs use digits only.
Watch the letter I and the digit 1: the same rule applies.
Test the check digit: enter the NMI into the NMI Checksum Digit Calculator.

If your bill shows 10 digits and a form asks for 11, the checker calculates the missing check digit for you.

Step 5 — What the Energy Made Easy NMI Lookup Tool Does

Energy Made Easy is the federal government website for comparing electricity plans. Its NMI Lookup Tool asks you to enter an NMI that you already have.

What it needs from you: an NMI you already found on your bill or in your retailer portal.
What it returns: a list of electricity plans available at your address.
What it does not do: it does not search for an unknown NMI.

Complete Steps 1 to 4 before you open any plan comparison tool. For what the number does once you have it, see what is an NMI useful for.

Whole-Home Energy Assessments From Your NMI Details

Once you have your NMI, keep it with your other property details. In a whole-home energy assessment, an assessor uses those details to right-size a solar, battery, or all-electric plan for your home.
