What is a MIRN and where do I find it?

  • Residential natural gas

    Every natural gas meter in WA features a Meter Installation Registration Number, also known as a MIRN.

    This unique 11-digit number is assigned to your gas service by the ATCO Gas, who maintains WA’s natural gas network, and identifies your gas delivery point.

    You’ll find your MIRN on the back page of your gas bill – but it should also be featured on your property’s natural gas meter.

    If you’re having any problems finding your MIRN, we’re here to help on 13 21 80.
