To know if someone has blocked you on Snapchat, several clear signs can help you determine this:
- You cannot find their username or profile when you search for it in Snapchat. If their profile doesn't appear at all, it is likely they have blocked you.
- Your previous conversations with the person disappear or you cannot send messages; messages may remain stuck on "Pending" or show an error like "Failed to send your message. Tap to try again."
- They no longer appear in your Friends List, and you cannot see their Bitmoji, Snap Score, or stories.
- If you use another Snapchat account (yours or a friend's) to search for the same username and the profile appears there but not on your main account, this strongly indicates that you have been blocked.
- Checking recent chats: if a conversation disappears suddenly without you deleting it, it could mean you are blocked.
In short, if the person’s profile is invisible or unsearchable from your account but visible from another, chats disappear or cannot be sent, and they’re removed from your friends list, you are probably blocked on Snapchat.
