What Is My MIRN & DPI Number?
There are a lot of buzzwords and acronyms that come with utilities, which can trip up even the most energy-savvy individuals!
When diving into your recent gas bill, an acronym might pop up that keeps you stumped on what it stands for and why a series of numbers follow it, being your MIRN or DPI number. Thankfully, we know a thing or two about anything and everything to do with utilities, that includes gas and all its meter number wonders.

What’s a MIRN/DPI?
The Meter Installation Reference Number or Meter Installation Registration Number (MIRN) is the identifying number displayed on your gas meter. This number can be found on your gas bill if you reside in Victoria (VIC), Queensland (QLD), or South Australia (SA).
This number is separate from your regular meter number which is simply used to identify the type of meter used at the property.
The Delivery Point Identifier (DPI) is the gas meter number acronym used by those residing in New South Wales (NSW), which can be found on your estimated bill similar to the MIRN counterpart.
Your energy retailers will use the MIRN/DPI to measure meter data and provide an accurate gas meter read. Access to the MIRN/DPI also allows the service provider to identify the meter and own meter types at your supply address and tell your existing retailer about any transfer to a new gas connection with ease.
