Does gta v story mode unlock online features?

Grand Theft Auto Online is the online multiplayer component that accompanies Grand Theft Auto V. According to the Wikipedia entry cited, it is an online action‑adventure game developed and published by Rockstar and is released alongside the main game on all platforms. The description does not mention any requirement to complete the story mode before accessing online play. Therefore, players can begin playing GTA Online without needing to finish the single‑player campaign. This means that online features are part of the base game rather than being unlocked by story progression.
