What is an MPAN?

Your Meter Point Administration Number (MPAN) is used to identify the electricity supply for your property. You might also hear it called your ‘supply number’, ‘M number’ or ‘endpoint’.

You can find your MPAN on your electricity bill.

It's 21 digits long and always begins with 'S'. You only need the last 13 digits.

You might be asked for your MPAN when you change electricity suppliers. It’s a good idea to check bills from your old and new suppliers to make sure it’s the same on both.
