A meter serial number (or 'meter ID') is an alphanumeric reference used in Great Britain to identify an electricity meter. Although meter serial numbers are intended to be unique, this can not be assured and duplicate serial numbers do exist. There are a variety of formats used over many years, but many meter serial numbers take the form A##AA###### (e.g. S06DS123456). The first letter indicates the manufacturer, the first two digits indicate the year the meter was calibrated and certified, and the second letter (or pair of letters) indicates the company that purchased the meter. The five/six digit sequence is a serial batch number. There may be a space separating the groups of numbers and letters. Electric meters in other countries besides Great Britain do not necessarily follow this standard.

Fronius Smart Meter Serial Number
This number is 21 digits long, consists only of numbers and uniquely identifies your supply point to the supplier. This identifying reference is important because the energy supplier can be sure to take over the correct property and bill the right meter if the MPAN is there. In Addition, before utilities accept and deploy Smart Meters, these devices must meet a number of national standards and comply with state and local codes designed to ensure proper operation, functionality and safety. In particular, Smart Meter and Smart Meter installations are typically designed to conform with and certified to comply with: 5. Anyone can add credit to a MeterPay Smart Meter - all you need to know is the Serial Number and Installation Post Code.
