MPRN

The MPRN (Meter Point Reference Number) is the gas equivalent of an MPAN for electricity. Every gas supply point in Great Britain has a unique MPRN that identifies it in industry systems.

Key facts about MPRNs:

• 6 to 11 digits long (most commonly 10 digits)
• Unique to each gas supply point
• Does NOT encode region information (unlike electricity MPANs)
• IGT (Independent Gas Transporter) MPRNs start with 74, 75, 76, or 77
• Found on gas bills and meter documentation

Structure differences from MPAN: While an electricity MPAN contains encoded information (DNO region, LLFC, Profile Class, etc.), an MPRN is simply a unique identifier. To determine the GDN region, LDZ, or any other information about a gas supply point, you need to look up the MPRN in industry databases or use the postcode.

Where to find your MPRN:

• Gas bills (usually near the meter serial number)
• Welcome pack from your gas supplier
• The gas meter itself (sometimes)
• By calling your gas supplier

Validation: MPRNs can be validated by checking:

• Length (6-11 digits)
• All numeric characters
• Exists in Xoserve's central database
