Can you play gta online after finishing the single player story?

The only verified source discusses Grand Theft Auto Online as an online multiplayer component of Grand Theft Auto V, detailing its release dates, platforms, and gameplay mechanics. It does not mention any prerequisite of finishing the single‑player campaign, nor does it state any restriction on playing the online mode after the story. Therefore, based on the available information, we cannot confirm whether the online mode requires completion of the single‑player story or can be accessed independently.
