Instagram does not allow users to see exactly who shared their post. However, if the post is shared to someone's public Story and they tag you, you will get a notification with their username. For professional (Business or Creator) accounts, you can see how many times your post was shared through Instagram Insights, but the specific accounts that shared it are not revealed. Additionally, for public accounts, you may see who reshared your post to their Story via the "View Story Reshares" feature, but this is limited and does not show shares via private messages or private Stories.
Key Points:
- You cannot see a list of usernames who shared your post via Direct Messages or private shares due to privacy.
- If someone shares your post to their public Story and tags you, you get a notification.
- For Business or Creator accounts, Instagram Insights shows the number of shares but not the individual sharers.
- The "View Story Reshares" option lets you see who shared your post to their Story if their account is public and the Story is active (24 hours).
- Shares via private Stories or DMs remain private and are not disclosed.
This means the ability to see who shared your Instagram post is very limited and mostly depends on public sharing with tagging or Story resharing visibility on professional accounts.
