What happens when someone blocks you
When someone blocks you on a messaging app, you lose the ability to send them messages through that app. Your messages will not go through, and you will not receive a notification telling you that you have been blocked — you will only discover it when your messages stop getting responses or when you try to send one and see an error.
Different apps handle blocking differently. On some platforms, your past messages remain visible to you but not to them. On others, the entire conversation disappears from your view. The person who blocked you can still see your old messages if they choose to unblock you later, but they cannot see anything you send after the block takes effect.
Blocking is not the same as muting or silencing notifications. A muted contact can still receive your messages — they straightforward will not hear alerts about them. A blocked contact receives nothing.
Key Takeaways
- Blocked messages do not go through on the app where you were blocked, so trying again on the same platform will not work.
- You can reach someone who blocked you through a different messaging app, phone call, email, or in person if you have another way to contact them.
- Creating a new account on the same app to contact someone who blocked you may violate that app's terms of service and could result in both accounts being suspended.
- If someone has blocked you, they have chosen not to receive messages from you on that platform, and respecting that choice is important.
Using a different messaging app or contact method
The most straightforward way to reach someone who blocked you is to use a different platform. If they blocked you on WhatsApp but you have their phone number, you can text them through SMS. If they blocked you on Instagram, you can try Facebook Messenger, email, or a phone call. Each platform and method is separate, so a block on one does not carry over to the others.
Before you contact them through another channel, consider why they blocked you. If the block was intentional and recent, sending a message through a different app may feel like you are circumventing their choice. Many people block specifically because they do not want further contact, and reaching them another way can feel like harassment to them, even if that is not your intent.
If you have a legitimate reason to reach them — you share children, you work together, or there is an urgent matter — a single message through an alternative method is reasonable. Keep it brief, explain why you are contacting them through a different channel, and do not follow up if they do not respond.
Why creating a new account is not a solution
Some people try to contact someone who blocked them by creating a new account on the same app. This almost never works and often makes the situation worse. Most messaging apps can detect when the same person creates multiple accounts, especially if the new account tries to contact the same blocked person shortly after the block.
Creating a new account to bypass a block violates the terms of service of virtually every major messaging platform. WhatsApp, Instagram, Facebook Messenger, Telegram, and Signal all prohibit this. If the app detects what you are doing, both your original account and the new one can be suspended or permanently banned.
The person who blocked you may also report the new account as spam or harassment, which speeds up the app's action against you. Even if the app does not catch it when ready, you risk damaging your reputation and any chance of future contact if they discover you created a fake account to reach them.
When you genuinely need to contact them
If you have a real reason to reach someone who blocked you — a shared child, a business matter, a family emergency — use the most direct method available outside the app. A phone call, a text message to their phone number, or an email is more appropriate than trying to work around the block.
When you do contact them, be direct about why you are reaching out. Do not pretend you did not know they blocked you or act surprised. Say something like: "I know you blocked me on Instagram, but I need to talk to you about [specific reason]. Can we discuss this?" This shows respect for their choice while explaining why you felt you needed to reach them anyway.
If they do not respond to your alternative contact method, that is a clear signal that they do not want to communicate with you. Continuing to try after that crosses into harassment, regardless of your reason for wanting to contact them.
Understanding why someone might block you
Blocking is usually a deliberate choice, not an accident. People block for many reasons: they want to end a relationship or friendship, they feel unsafe, they are overwhelmed by messages, or they straightforward do not want contact anymore. Understanding the likely reason can help you decide whether reaching out through another method is appropriate.
If the block came after a conflict, the person may need time before they are willing to talk. Respecting that time, even though it is frustrating, is the only way to leave the door open for future communication. Trying to force contact through another channel often hardens their position.
If you are unsure why you were blocked, you can ask a mutual friend if they know, but do not ask them to relay messages or convince the person to unblock you. That puts them in an uncomfortable position and rarely works.
What to do if you think the block was a mistake
Sometimes blocks happen by accident — a pocket dial, a misclick, or confusion about how the app works. If you think this might have happened, wait a few days before trying to contact them through another method. If it was truly accidental, they may unblock you on their own once they realize.
If you do reach out, keep your message light and give them an straightforward way to respond without committing to a conversation. Something like "Hey, I think I might have been blocked by accident — let me know if that was intentional or not" is better than a long explanation or apology they did not ask for.
Do not assume the block was a mistake just because you do not understand why it happened. Most blocks are intentional, even if the reason is not clear to you.
Respecting boundaries after a block
A block is a boundary. The person who blocked you has told you, through their actions, that they do not want messages from you on that platform. Respecting that boundary, even if you disagree with it or do not understand it, matters more than your desire to reach them.
If you contact them through another method and they do not respond, that is a second boundary. Continuing to try after that is not persistence — it is ignoring what they have clearly communicated.
Moving forward without contact is hard, especially if the relationship ended badly or you feel there is unfinished business. But the other person's right to not hear from you outweighs your need to say something. If you need to process the situation, talk to a friend, family member, or therapist instead.
Frequently Asked Questions
Can I see if someone blocked me or if they just deleted their account?
Not always. On some apps like Instagram, you can search for their profile — if it does not appear and you know the exact username, you were likely blocked. On others like WhatsApp, there is no reliable way to tell the difference between a block and a deleted account without trying to message them. If your message does not go through and you get an error, you were blocked.
If someone unblocks me, can they see the messages I sent while I was blocked?
No. Messages sent while you were blocked do not exist in their message history. If they unblock you, they will only see messages you send after the unblock. Your old messages from before the block are still there, but anything sent during the block period is gone from their view.
Will they know if I try to message them while blocked?
They will not receive a notification that you tried to message them. Your message will fail to send on your end, usually with an error message. They will have no record that you attempted contact unless you tell them or try to reach them through another method.
Is it illegal to contact someone who blocked you?
Sending one message through an alternative method is not illegal. Repeatedly contacting someone after they have made clear they do not want contact can become harassment, which is illegal in most places. The line depends on how many times you contact them, how aggressive the messages are, and whether you are causing them distress.
What if I blocked someone by mistake and want to unblock them?
Go to your blocked contacts list in the app and find their name, then select unblock. On most apps, this is in Settings under Privacy or Blocked Users. Once you unblock them, they will not be notified, but they will be able to message you again. You can also see their messages from before the block.
