Finding your EAN code in Belgium
An EAN code is an eighteen-digit identifier for a single electricity or gas supply point in Belgium. It belongs to the connection, not to you and not to your supplier, and it begins with 54. A home connected to both energies has two separate codes, one per meter, and confusing them switches the wrong contract.
Steps
Look at the technical block of an energy invoice
The code sits in the header or in the technical section of the bill, labelled EAN code or supply point number. It has eighteen digits and starts with 54, often printed in groups to make it readable.
Check which energy each code belongs to
If the home has electricity and gas, two distinct codes exist and they look almost identical at a glance. Read the label next to each one before quoting it, because giving the gas code for an electricity contract sends the request to the wrong meter.
Read the label on the meter itself
Most Belgian installations carry a sticker on or beside the meter showing the EAN code. This is the most reliable check when several meters are grouped in a shared technical room and the handwritten flat numbers cannot be trusted.
Ask the distribution network operator if you have no bill
A newcomer, or anyone moving into a home whose meter was inactive, has no invoice to read. The distribution network operator for your commune can supply the code on the basis of the address and the meter serial number.
Why an address is not enough
An address is ambiguous in ways that a database cannot resolve. A building holds several flats, a house can have two meters, and the same property is sometimes numbered differently in the population register and in the network operator's records.
The EAN code removes all of that. It designates one physical connection, uniquely, in the systems of every network operator and supplier in the country. That is why every supplier switch and every move is processed on the code rather than on the street name.
The failure mode is worth understanding. A wrong code does not produce an error message; it produces a perfectly valid switch of somebody else's meter. Untangling that involves two suppliers, one network operator and a neighbour, and it takes weeks.
When you will be asked for it
When you change supplier: the incoming supplier needs it to identify the supply point it is taking over, and will not process the request without it.
When you move house: it links the readings on the energy transfer document to the correct meter, at both the old and the new address.
When you request an intervention from the network operator, for a defective meter, a change of connection capacity or the installation of a digital meter.
When you use an official regulator comparison tool, since some of them retrieve your real consumption profile directly from the code instead of asking you to estimate it.
Digital meters and shared buildings
The rollout of digital meters differs by region and is coordinated by the network operators, not by suppliers. Replacing a meter does not change the EAN code, because the code identifies the connection point rather than the device attached to it.
In apartment buildings the meters are usually grouped in a cellar or technical room. Do not rely on a flat number written in marker pen by a previous occupant: match the code on the official label, or have the network operator confirm which code is yours.
If you cannot resolve the ambiguity, ask the network operator to identify the connection from the meter serial number. That number is stamped on the device itself and cannot be reassigned by anyone in the building.
Frequently asked questions
Where do I find my EAN code without an invoice?
Ask the distribution network operator for your commune, which can retrieve it from the address and the meter serial number. In most installations the code is also printed on a label fixed on or beside the meter itself.
Does the EAN code change when I switch supplier?
No. It identifies the physical connection and stays attached to the supply point whatever the supplier or the occupant. It only changes if the installation itself is modified, for example when a connection is split or created.
Do electricity and gas have different codes?
Yes. Each energy has its own supply point and therefore its own eighteen-digit code. They look similar, so check the label beside each code before passing it to a supplier or entering it in a comparison tool.
What does a Belgian EAN code look like?
Eighteen digits beginning with 54, usually printed in groups for legibility. The 54 prefix identifies Belgium in the European numbering scheme for energy supply points, which is why every Belgian code starts the same way.
