The Ibrox club were barred from voting in recent debates on the future of the Scottish game following their formation as a newco in the wake of last summer's liquidation crisis.
New clubs joining the Scottish Football Association at that time were forced to serve five-year spells as associate members before they were given full voting rights.
But the SFA's 93 member clubs voted to scrap associate memberships at the governing body's Annual General Meeting earlier this month, meaning Rangers are now able to rejoin the rest of Scotland's 41 league clubs to have their say on major issues.
Rangers' chief executive Craig Mather said: "This is the status Rangers should have and we look forward to playing a full and leading part in the rebuilding of Scottish football.
"That's what all of us; everyone who cares about the game should be working towards. It is also important that Rangers' voice be heard because this club is too big and too important to be ignored.
"Stage one has been completed but the journey continues and we hope to meet and make many more friends along the way. However, now that we are full members we will be determined to make our own views on the game's future known.
"Everyone knows Rangers have had to tread carefully but we will now be moving forward with greater purpose and determination on and off the pitch as well as within the corridors of power."
Rangers have been handed an away tie against Albion Rovers in the first round of the Ramsdens Cup. The match is scheduled to be played on July 27.
