An MPAN is short for Meter Point Administration Number which is a unique number assigned to a property with an electric supply within the UK. It is usually found on the electricity bill issued by your supplier. This is sometimes called a Supply Number but it should not be confused by the meter serial number or the customer reference number.
The full MPAN is made up of a 21 long numeric number and can usually be found on a recent electricity bill as seen below.
The profile class simply is the type of supply for the meter and reflects the price and how the bill is calculated.
|00||Half-hourly supply (import and export)|
|02||Domestic Economy Meter of 2 or more rates|
|04||Non-Domestic Economy 7|
|05||Non-domestic, with MD recording capability and with LF less than or equal to 20%|
|06||Non-domestic, with MD recording capability and with LF less than or equal to 30% and greater than 20%|
|07||Non-domestic, with MD recording capability and with LF less than or equal to 40% and greater than 30%|
|08||Non-domestic, with MD recording capability and with LF greater than 40% (also all NHH export MSIDs)|
The MTC is a 3 digit code that reflects the various registers a meter may have, whether it be a Single Rate, Day Night split, or even a Seasonal Time of Day

|800 - 999||Codes common across the Industry|
The Line Loss Factor Class or LLFC is used to identify the related Distribution Use of System (DUoS) charges for the MPAN. The figure reflects both the amount of distribution infrastructure used to supply the exit point and the amount of energy lost through heating of cables, transformers, etc.
Mainland UK is divided into fourteen distribution areas as shown in the image below. For each area a single company, the distribution network operator, has a licence to distribute electricity. They effectively carry electricity from the National Grid to the exit point (each has a unique MPAN and a possibility of several meters) where the customers are. The owner of the distribution network charges electricity suppliers for carrying the electricity in their network. Their DNO licensed regions are the same geographic areas as the old nationalised electricity boards

The final digit in the Meter Point Administration Number is the check digit, and validates the previous 12 (the core) using a modulus 11 test. The check digit is calculated thus:
