What is a NMI?

NMI stands for National Metering Identifier – a unique 10 digit value for every grid connection point to your electrical supply. The NMI is used to match properties with the right energy account, so you are not billed for someone else’s usage.

In general, NMI's contain both the state and the distribution patch the connection point belongs to.  For example, Citipower (VIC) NMI blocks generally are from 6102000000 to 6103999999 or VAAA000000 to VAAAZZZZZZ and Energy Australia (NSW) NMI blocks generally are from 4102000000 to 4104999999 or NCCC000000 to NCCCZZZZZZ.
