Finding your NMI and MIRN

What is a NMI?

Your NMI (National Meter Identifier) is the reference of your address in the electricity market. It's different to your meter number and stays linked to your property, even if your meter is replaced.

Your property has a National Meter Identifier. If you can tell us this number when you're signing up, it will help us match your address.

What is a MIRN?

Like the NMI for electricity, your MIRN (Meter Identification Reference Number) is the reference of your address in the gas market. Your gas meter also has a separate meter number which isn’t the same as your MIRN.

Where do I find my NMI and MIRN??

Your NMI is located at the top of your Arcline by RACV electricity bill on the first page. Your MIRN can be found in the same place on your gas bill.

If you're not already an Arcline by RACV customer, you'll be able to find your NMI or MIRN on your latest bill from your current energy retailer.

Why do the NMI and MIRN matter?

When we switch the billing for your property from your current retailer to Arcline by RACV, we need to get a perfect match in the industry operator's systems - knowing your NMI and/or MIRN helps us to do that.

Some retailers may potentially bill customers for the wrong NMI or MIRN. This means they've attached the wrong meter data to someone else's bill and in some cases they've switched the wrong customer.

That's why we use a combination of data sources to get the match right: your NMI or MIRN, address, meter configuration and your account information.
