Find out your Flarm-ID

Often pilots want to Opt-In or Opt-Out but they don't know where to get their Flarm-ID(RadioID) or ICAO24 Address from.

This page should help to find out your Flarm-ID or ICAO24 Address.

Flarm-ID

Classic Flarm

To be clear the Radio-ID is not the Serial number of the Unit.
The ClassicFlarm Serial number can be found on the case. Starting with the Hardwareversion like F5… F6… F7…followed by 4 numbers.

Sticker at the Bottom of Case

If your Flarm is an IGC-Valid-Logger you might have a chance that there is a sticker at the bottom of your device telling you what the Flarm-ID is.

Download IGC Files and CSV File to Micro-SD-Card

If your Flarm is equipped with a Micro-SD-Card slot then you can insert a card and startup your Flarm to download the IGC Files. Together with the downloaded IGC files there will be a flarmdev.csv file.
Open it in any text editor (or Excel) and find an entry for each Downloadprocedure.
Search for the last line and look at ID=

Readout from IGC File

Download some IGC Files from your Flarm. Use Micro-SD-Card or XCSoar (connected via cable or Bluetooth) or just download them from the OLC-Server.
If you open the IGC-File in a text editor you can scroll down a bit till you find the Line starting with LFLA and ID
