Do gta online players have to complete gta v story missions?

Grand Theft Auto Online is a multiplayer mode that operates alongside Grand Theft Auto V. Players can access GTA Online after installing the base game, but the online experience does not require completion of the single‑player storyline to begin playing. While the base game itself includes a narrative that can be finished, the online mode offers a separate progression system featuring missions, heists, and other activities that can be undertaken independently of the main story. As no source confirms a mandatory link between finishing the storyline and gaining access to online content, it is safest to assume that the requirement is not enforced. Players who choose to play online can therefore start without having completed the single‑player missions.
