When you're blocked on an iPhone, your iMessages usually won't show "Delivered", but sometimes they might, especially with newer iOS versions or temporary glitches, meaning the message reached Apple's servers but not the device; the key signs are no "Delivered" status, calls going straight to voicemail, or green SMS bubbles (if iMessage fails), but the most reliable check is persistent non-delivery or calling after a delay, as the recipient never sees it.
Check the message status
For iPhone users running iOS 16.5 or later, the message will say Delivered even if you've been blocked. If you're using iOS 16.4 or earlier and your last message has Delivered below it, rest assured you haven't been blocked. If your message says Not Delivered, don't panic.
You can suspect someone blocked you on an iPhone if calls go straight to voicemail (maybe after one ring) and iMessages don't show "Delivered" or "Read" receipts, but these signs can also mean their phone is off; the most reliable test is trying to call them using a different number or *67 to hide your caller ID, and if it rings normally on their end but goes to voicemail from your real number, you're likely blocked.
On iPhones running iOS 16.5 or later, the space below your last text will say Delivered whether you're blocked or not on iMessages. If your phone is running iOS 16.4 or earlier and you see Delivered beneath your last text, you're not blocked.
It's important to note that the sender won't be notified that their message was blocked or undelivered.
Your text messages don't deliver
If your text messages aren't going through, it could mean the intended recipient has blocked your number. Most devices and messaging platforms indicate undelivered messages with a “Not Delivered” status message or a symbol, like a red exclamation point.
If it still says “Delivered,” a few things might be going on: You may not be blocked, and they're just ignoring or not seeing your messages. They might have turned off call notifications or set up Focus modes (like Do Not Disturb), which would send calls straight to voicemail but not affect message delivery.
What Happens If You're Blocked on iPhone
Muting helps you ignore someone without preventing them from doing anything. Blocking someone prevents them from messaging you, commenting on your observations, identifying your observations, and otherwise interacting with you on iNaturalist.
If you're blocked by someone, your calls will go straight to voicemail, and your voicemail messages will head to the “Blocked” section immediately. The other person won't receive your calls, won't be notified you called, and won't see a badge for your voicemail.
Check the chat bubble color
This is only true if both of you use iMessage on iPhones. This isn't a foolproof method. You may see a green bubble in the following situations: If the other person switched to an Android phone, their bubble may have turned green.
You can suspect someone blocked you on an iPhone if calls go straight to voicemail (maybe after one ring) and iMessages don't show "Delivered" or "Read" receipts, but these signs can also mean their phone is off; the most reliable test is trying to call them using a different number or *67 to hide your caller ID, and if it rings normally on their end but goes to voicemail from your real number, you're likely blocked.
Messages that are sent or received won't be delivered. Also, the contact won't get a notification that the call or message was blocked.
Apple support confirms that if you are blocked, it will NOT say delivered.
If a person blocks you on iMessage, then they won't get any of your texts at all.
If you've been blocked, your messages won't show a “Delivered” status or a read receipt, and you may notice the iMessage “blue-to-green” change. If your messages switch from blue (iMessage) to green (SMS), it signals that Apple's servers are no longer delivering your messages to that person's device.
You've likely been blocked if your call goes straight to voicemail. No Delivery notification beneath your last sent iMessage can mean you're blocked.
iMessage won't deliver on iPhone
iMessage includes delivery statuses and read receipts, so you can see whether your message went through. If your texts consistently show no delivery, it may be a sign you've been blocked. If your message goes through, you'll see Delivered beneath it.
Will I receive old texts sent while they were blocked? Blocked messages will not come through when unblocked. While someone is blocked, any sent text messages will be blocked by Messages. You won't be able to retrieve them.
An easy way of knowing you've been blocked is to send a message with read receipts on. If the message doesn't say delivered that means you're blocked. Calling is slightly different, it rings a couple times and goes to voicemail. You can leave a message which they will get but they won't receive a notification for it.
If you text someone who blocked you, you won't see an alert that you've been blocked, but they won't get your text. If you usually see "Delivered" when you text them but don't see it now, or their message bubbles are suddenly green instead of blue, you may be blocked.
According to Apple Support, there is no definitive indicator that confirms you've been blocked via iMessage. Certain signs, like messages not showing “Delivered,” may suggest it — but they can also occur for other reasons like signal issues or device settings.
