Have you ever sent a message and wondered why there’s no reply? Or why a friend’s profile looks different? Many people face this on apps like WhatsApp or Instagram. In this guide, you’ll learn how to know if someone blocked you. We’ll cover the main signs on top platforms. This helps you spot blocks without guessing. It’s normal – about 17% of U.S. adults have unfollowed or blocked someone due to shared content, per Pew Research. Don’t worry; we’ll keep it simple and show you what to do next.
Why People Block Others
People block for many reasons. It might be to avoid arguments or protect privacy. On apps, blocking stops contact. It hides profiles, messages, and updates. But it’s not always personal. Sometimes, it’s about space. Knowing the signs lets you move on fast. Let’s start with WhatsApp, a top messaging app with over 3 billion users.
How to Know If Someone Blocked You on WhatsApp
WhatsApp is popular for chats and calls. If blocked, you see changes. Check these signs step by step. They often happen together for sure proof.
Bold key steps:
- Check last seen and online status. Open the chat. Look under their name. If it says “last seen” or “online” before but now nothing, it might be a block. But some hide this in settings.
- Look at profile picture. Tap their name. If the photo is gone or stuck on an old one, that’s a clue. Blocked users don’t see updates.
- Send a message. Type something. See the ticks. One gray tick means sent but not delivered. Two ticks mean delivered. Blue ticks mean read. If it stays at one tick forever, likely blocked.
- Try a call. Hit the phone icon. If it rings but never connects, or goes straight to busy, check for block.
- Add to a group. Make a new group. Try to add them. If you can’t, that’s strong proof.
These signs match WhatsApp’s help center. For example, messages show one check mark if blocked. Test with a friend to compare. If all match, you’re probably blocked. Remember, phone off or no internet can mimic this short-term.

How to Know If Someone Blocked You on Instagram
Instagram focuses on photos and stories. Blocks hide everything. Here’s how to spot one.
Bold key terms:
- Search for their profile. Use the search bar. Type their username. If nothing shows, or it says “user not found,” check for block. Deactivated accounts look similar.
- Check from DMs. Open old messages. Tap their name. If it says “Instagram User” with no photo or posts, likely blocked.
- See post count. If you find the profile but see “No Posts Yet” and zero followers, while others can view it, you’re blocked.
- Try to follow or message. Hit follow. If it fails or messages don’t send, that’s a sign.

How to Know If Someone Blocked You on iMessage
iMessage is for Apple users. It uses blue bubbles for iPhone chats. Blocks change this.

- Look at bubble color. Send a text. Blue means iMessage. Green means SMS. If it switches to green suddenly, possible block.
- Check delivery status. Under your message, see “Delivered” or “Read.” If nothing shows, or it says “Not Delivered,” test for block.
- Make a call. Dial them. If it rings once then voicemail, or no ring, they might block you.
- Send from another number. Use a friend’s phone. If it goes blue and delivers, you’re blocked on yours.
From Apple communities, like this discussion, no “Delivered” often means blocked. But Do Not Disturb or no signal can cause it too.

Facebook connects friends. Blocks remove all ties.
