Until 1960, only one of them, the AGGL, was a member of the WAGGGS. The AGGL and the Lëtzebuerger Guiden (predecessor of the LGS) formed the joint Bureau des Liaison in 1958, and in 1960 the WAGGGS World Conference transferred the membership to this umbrella federation.
The LGS is also a member of Scouting in Luxembourg (formerly Luxembourg Boy Scouts Association).
