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 residences. The gas equivalent is the Meter Point Reference Number. The system was introduced in 1998 in order to provide a competitive environment for the electricity companies, and allows consumers to switch their supplier easily 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 indeed none where it is an unmetered supply. A supply receiving power from the network operator (DNO) has an Import MPAN, while generation and microgeneration projects feeding back into the DNO network are given Export MPANs. An MPAN is commonly separated into two sections: the core and the supplementary data. The core is the final 13 digits and is the unique identifier. The supplementary data gives information about the characteristics of the supply and is the responsibility of the supplier. The full MPAN is required to be depicted on electricity bills (the boxes on the top and bottom line
