When people with private profiles tag posts, they won’t appear publicly on hashtag pages.

Numbers are allowed in hashtags. However, spaces and special characters, like $ or %, won’t work.

You can only add hashtags to your own posts. You can’t tag other people’s photos/videos.

You can use up to 30 hashtags on a post and 10 on Instagram Stories.
