The Zählpunkt Number

The Zählpunkt number is the unique ID of your metering point in the Austrian energy network. You need it to connect your Smart Meter to energiedaten.at.

What Is the Zählpunkt Number?

The Zählpunkt number is a 33-character code that always starts with "AT" — for example AT0010000000000000000000000123456. It does not identify the physical device, but the logical metering point in the EDA network.

Where to Find Your Zählpunkt Number

On your electricity bill: Look for the label "Zählpunktnummer", "ZP-Nummer", or "Metering Point ID". It is usually on the second or third page of the bill.

In your grid operator's customer portal: Log in to the online portal. Under "Meine Zählpunkte" or similar, you will find all Zählpunkt numbers for your installation.

On the Smart Meter display: Many Smart Meters show the Zählpunkt number directly on the display. Scroll through the menu items until you see a 33-character number starting with "AT".

Common Confusion: Zählpunkt Number vs. Meter Number

The Zählpunkt number (33 characters, starts with AT) identifies the metering point — this is what you need here.

The meter number is the serial number of the physical device (shorter, often alphanumeric). It appears on the meter's nameplate and is not required for the EDA connection.

Two Zählpunkt Numbers?

If you both consume electricity from the grid and feed electricity back in — for example through a photovoltaic system — you have two separate Zählpunkte: one for consumption and one for feed-in. Both have their own 33-character numbers.

You can connect both Zählpunkte in energiedaten.at. More about this: Consumption and Feed-in.
