What You'll Learn

Your MPAN is on your electricity bill
Your MPAN, or Meter Point Administration Number, is a unique 21-digit identity reference number for your electricity meter. It is sometimes referred to as an 'S number' or 'Supply Number' and begins with the letter 'S'.
The MPAN is used to identify your electricity supply point and is unique to your premises. It won't change if you switch suppliers. It is made up of several smaller numbers that contain different pieces of information. For example, the first two numbers after the 'S' refer to your meter's profile class, which indicates your typical electricity usage.
You will only need the last 12 or 13 digits of the MPAN. It is important to note that the MPAN is different from your meter serial number, which can be found on your meter box. The meter serial number can change if your meter is upgraded or replaced, while the MPAN remains the same.
