Meter Point Administration Number
A Meter Point Administration Number, also known as MPAN, Supply Number or S-Number, is a 21-digit reference used in Great Britain to uniquely identify electricity supply points such as individual domestic properties. The system was introduced in 1998 to aid creation of a competitive environment for electricity supply companies, and assists consumers to switch their supplier as well as simplifying administration. Although the name suggests that an MPAN refers to a particular meter, an MPAN can have several meters associated with it, or none where it is an unmetered supply. A supply receiving power from the distribution network operator (DNO) has an import MPAN, while generation and microgeneration projects feeding back into the DNO network are given export MPANs. The equivalent for gas supplies is the Meter Point Reference Number and the water/wastewater equivalent for non-household customers is the Supply Point ID.
