MPAN checker

Paste a supply number and this will tell you which distribution network operator covers it, and whether the number itself is valid.

MPAN (supply number)

Enter the 13-digit bottom line. Spaces are fine, and you can paste the whole block from a bill.

How it works

The bottom line of an MPAN is thirteen digits. The first two identify the distribution area, which is how this finds your DNO. The last is a check digit calculated from the other twelve, so a mistyped or misread number can be spotted arithmetically — useful when you’re reading one off a photograph of a meter.

Independent DNOs — GTC, ESP, Last Mile and similar — operate their own ID ranges and aren't listed below. A valid MPAN with an ID outside 10–23 is almost certainly one of those.

Independent DNOs

Private networks, typically on newer housing estates and commercial developments. These change hands more often than the regional areas, so an unrecognised ID may simply be a newer licensee.
