Facebook's Help Center explains how hashtags work but sets no limit: write # with a topic or phrase as one word, numbers allowed, no punctuation or symbols such as $ and %. Clicking a hashtag opens a feed of posts that include it, and people can search for one.
Facebook gives no advice on how many to use. Hashtags are part of the post text, so they count toward its 63,206 characters, and reels published through Meta's API carry them in the description.
Facebook sets no number. A few clear topic tags read better than a long list, and they all count toward the post.
No spaces, no punctuation and no symbols such as $ or %. Numbers are fine.
Clicking a hashtag shows every post that uses it, so one branded tag can collect a campaign in one feed.
Who can see a hashtagged post follows the post's own audience setting.
Write the post for people, then add hashtags. Facebook gives no sign that more hashtags bring more reach.
Save the few tags you use most so each post gets them without retyping.
The rules come from Facebook's Help Center and Meta's Reels API reference, read on October 17, 2026. Facebook publishes no hashtag limit and no advice on how many to use, so the page gives no number.
