MPAN Checker – What Is Your MPAN And Why Is It Important?

MPAN – What is it and Why is it Important?

An MPAN number is a Meter Point Administration Number and they act as labels for electricity meters in the UK. They are also sometimes called Supply Numbers or S-Numbers

There is an equivalent for gas, too, known as MRPN or Meter Point Reference Number.

You can use your MPAN to check and discover a lot of things about your energy supply. For this our MPAN Checker is used to assist the process.

Enter your 21-digit electricity MPAN below:

Below you will find a guide to why checking your MPAN is important, what information it can provide you with, and how we help you figure everything out!


It is a 21-digit reference used to identify individual electricity meters. They were introduced in 1998 to help simplify administration for energy suppliers and make it easier for customers to switch their supplier.

Mpans Explained

The number is separated into two sections: the core and the top-line data.

  • The core is the final 13 digits. This is the unique identifier of your meter.
  • The top-line data explains characteristics of the supply you are provided with.

Thanks to the ease of our MPAN calculator we are able to remove the need for you to have to make sense of these numbers.

However, for your intrigue, below is a breakdown of what your MPAN number means:

Section Meaning
Profile Class This gives the supplier an indication of the property’s typical energy consumption. Domestic properties will be either in profile class 01 or 02
Meter Time Switch Code This refers to how many registers (sets of meter numbers or dials) your electricity meter has. Examples of this are single rate registers, day/night split register or a seasonal time of day register.
Line Loss Factor These numbers indicate the Distribution Use of System charges that your supplier is expected to pay for using the networks and cables in your area
Distribution ID These numbers identify the regional distribution company for your electricity supply. This company is responsible for the management of the wires that deliver electricity to your home.

This number can be useful to you if you need to figure out who operates the electricity network in your area.

Meter Point ID This number is unique within the distribution area, it identifies the specific meter.
Check Digit A sum calculated from the Distributor ID and Meter Point ID to verify both numbers.


You will need your MPAN number when you’re switching energy supplier or moving home; your new supplier will often ask for this number as part of the switching process.

Below you can see the differences between the two processes.

If you’re… Then
Swapping Suppliers You will be asked your current MPAN. Your MPAN won’t change because the MPAN number is associated with property and is not dependent on the energy supplier used.
Moving House You’ll need to provide the MPANs of both the old and the new property. Your local DNO will be able to tell you the necessary information regarding your new property.

You can also phone the National Grid’s Meter Number Helpline on 0870 608 1524.

It is also important to check your MPAN number in order to ensure it is valid and that you are paying for the correct energy supply.


Your MPAN can be found on your energy bills. If you do not have an energy bill for the property, as in if you have just moved in, instructions on what to do can be found above.

The MPAN comprises of different elements which relate to your energy supply. Your MPAN number can be validated and this is achieved by generating a checksum from 12 of the Core Identifier digits. This number is then compared to a check digit which is the final digit of the MPAN.

The MPAN Checker carries out these complicated steps for you in order to make it an incredibly easy process; we do all the work for you!

The steps we carry out are below:

  1. Note the final 13 digits from the MPAN, this is the Core Identifier
  2. Remove the final digit. This is the check digit and will be used later
  3. For the remaining 12 digits, multiply the first number by 3
  4. For the second digit, multiple it by the number 5 (the next prime number after 3)
  5. Repeat this process for each of the remaining 10 digits EXCLUDING the number 11 (7, 13, 17, 19, 23, 29, 31, 37, 41, 43)
  6. Calculate a checksum by adding up all these products (each of the 12 digits multiplied by successive prime numbers)
  7. Generate a check digit by using the checksum modulo 11 modulo 10
  8. Compare the calculated check digit to the last number of your sum total MPAN from step 6. If they match you have a valid MPAN number.

If you receive an invalid result from the MPAN checker it could mean several things:

  1. The coding could have returned the wrong result,
  2. The Profile Class and Distributor ID you entered may not be valid,
  3. You may not have completed the form correctly.

All you need to provide is the entire 21-digit number, broken into the groups illustrated in the first section of this guide.

Answering Your MPAN Questions

What do the digits on an MPAN mean?

The Meter Point Administration Number (MPAN) is a vital identifier used in the electricity supply industry to uniquely distinguish supply points. Each MPAN is made up of a combination of digits, providing valuable information about the supply and its characteristics.

The MPAN consists of two main components: the MPRN number, which stands for Meter Point Reference Number, and the electricity supply number, also known as the electricity MPAN. In some cases, it may also include gas MPRN numbers for properties with both electricity and gas supplies.

The MPAN number is divided into segments that represent different aspects of the supply. It includes a meter number, meter point administration number, and profile class, all of which help energy suppliers manage and bill the supply accurately. The digits within the MPAN correspond to specific details like distributor ID, meter serial number, and electricity supply point, enabling efficient communication between suppliers and distributors.

When switching energy suppliers, knowing your MPAN and MPRN numbers is essential. These numbers are typically found on your energy bill or, if unavailable, by contacting the helpline for assistance. As you move to a new property or change suppliers, the MPAN will remain the same, ensuring continuity and a seamless energy transfer.

Understanding the digits on an MPAN can be beneficial in assessing your energy consumption and making informed decisions to optimize your energy usage. As a customer, having access to this unique number helps you find the best energy deals, manage your energy bills efficiently, and ensures a smooth transition between suppliers.

If you require an additional MPAN, it’s essential to understand the process and implications involved. An MPAN, or Meter Point Administration Number, is a unique identifier assigned to each electricity supply point. It plays a crucial role in accurate billing and energy management.

If you need an additional MPAN, it usually means you are installing a new electricity supply point or adding more meters to your existing location. This is common for businesses that expand or property developers building new structures.

To obtain an additional MPAN, you must contact your electricity supplier or the Distribution Network Operator (DNO) responsible for your area. They will guide you through the application process and provide you with the necessary information, such as the new MPAN number and related details.

Keep in mind that an additional MPAN will be associated with a new meter, and each meter will have its unique identifying numbers, including the supply number and meter number. These numbers help differentiate the usage and billing for each meter at the premises.

Having multiple MPANs is common for commercial properties with separate units or multifunctional buildings. Each MPAN allows for individual energy monitoring and billing for each section.

When might I need my MPAN?

You might need your MPAN in various situations related to your electricity supply and energy management. The MPAN, which stands for Meter Point Administration Number, is a unique identifier assigned to your electricity supply point. Here are some instances where you would need your MPAN:

  1. Switching Energy Suppliers: When you decide to switch energy suppliers, your new provider will require your MPAN to ensure a smooth transition and accurate billing.
  2. Setting Up a New Electricity Supply: If you’re moving to a new property or setting up a new electricity supply point, you’ll need your MPAN for the registration process with the utility company or Distribution Network Operator (DNO).
  3. Managing Your Energy Bills: Your MPAN is essential for accurate billing and tracking your energy usage. It helps suppliers associate your energy consumption with the right meter and supply point.
  4. Contacting Your Supplier: When contacting your energy supplier regarding any issues or inquiries related to your electricity supply, they will often ask for your MPAN to access your account information.
  5. Meter Readings and Maintenance: Your MPAN is used to identify your meter, enabling accurate meter readings and maintenance operations by the DNO or metering company.
  6. Identifying Your Supply Point: The MPAN uniquely identifies your electricity supply point within the national energy database, allowing for efficient management and record-keeping.

What’s the difference between an MPAN and an MPRN?

The main difference between an MPAN and an MPRN lies in their respective purposes and the utilities they identify. An MPAN, or Meter Point Administration Number, is a unique identifier used specifically for electricity supply points. On the other hand, an MPRN, or Meter Point Reference Number, serves the same function but is exclusively used for gas supply points.

Both the MPAN and MPRN are crucial for accurate billing, energy management, and communication with energy suppliers. The MPAN is utilized by electricity suppliers to track usage, apply tariffs, and manage billing for individual electricity meters. It consists of various segments, including the supplier’s information, meter details, and profile class.

Similarly, the MPRN is essential for gas suppliers to identify and manage gas supply points effectively. Like the MPAN, the MPRN comprises specific segments, such as the distributor ID, meter serial number, and gas supply point details.

While the MPAN and MPRN share similarities in their structure and function, they are specific to their respective utilities—electricity and gas. Customers need to be aware of the distinction between these two unique numbers to ensure proper handling and management of their energy supplies.

Should I give out my MPAN number?

Your MPAN is an essential identifier for your electricity supply, and it is generally safe to provide it to your energy supplier or relevant authorities when required. Your MPAN, which stands for Meter Point Administration Number, helps ensure accurate billing and effective energy management. It contains vital information such as your supplier details, meter reference, and profile class.

While sharing your MPAN is generally safe, exercise caution when sharing personal information along with it. Your MPAN itself does not contain sensitive details like payment information or personal identification, but it is essential to protect it from unauthorized access.

When dealing with switching energy suppliers or addressing billing issues, you may need to provide your MPAN. This ensures a seamless transition to your new supplier and accurate billing for your energy usage.
