What's a MIRN and where do I find it?
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 ATCO Gas, which 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.
