The ability to identify other users in an Instagram post is typically limited to a maximum of 20 accounts. This function serves to credit collaborators, identify individuals in a photograph, or notify specific users of content relevance. The tagging feature is accessed during the post creation or editing phase, allowing the user to pinpoint individuals visible within the image or those directly related to the post’s subject matter.
Limiting the number of tags helps maintain post clarity and prevent tag spamming, ensuring a better user experience and preventing potential abuse of the platform’s notification system. Originally, Instagram’s tagging system was designed to be a curated method of connection, not a mass marketing tool. The enforced limitation promotes genuine engagement, rather than indiscriminate outreach.
