What is an MPRN and where do I find it?
An MPRN — Meter Point Reference Number — is the unique number identifying a gas supply point, usually six to ten digits. It is on your gas bill, and it stays with the property when suppliers or occupiers change. It is the gas equivalent of an electricity MPAN.

Where to find it
- On a gas bill, often labelled MPRN, M number or meter point reference.
- From Find My Supplier or the Meter Number Helpline on 0870 608 1524, using the postcode and address.
- Not on the meter itself — the number on the meter is the serial number, which is a different thing. The serial number identifies the physical box; the MPRN identifies the supply point.

| Where | Gas bill | Electricity bill, in the "supply number" box |
| Tells you | Which gas supply point | Which supply point, plus profile class, metering and distribution area |

Why quotes need it
Without an MPRN a gas price is an estimate against a postcode. With it, the supplier can see the supply's characteristics and annual quantity and price the actual meter. It is also what you need to serve notice, register a change of tenancy or submit a VAT declaration, so it is worth keeping with your contract paperwork rather than digging it out each time.
