What is a ‘NMI’ number and where can I find it?

NMI stands for National Metering Identifier. 

Your NMI: 

  • Will always start with the digits ‘800’ and is 11 digits in length 
  • Can be found on you ‘self-reading due’ reminder notification from Western Power (either email or SMS), and 
  • Can be found on your most recent Synergy bill, under the section ‘Your energy supply details’ on page 2. 

Don’t have a reminder or electricity bill handy? Please contact Synergy to be provided with your NMI
