You know someone blocked you on WhatsApp by observing multiple signs: messages only show one grey tick (sent, not delivered), you can't see their "Last Seen/Online," their profile picture doesn't update (or disappears), WhatsApp calls won't go through, and you can't add them to a group. If you see all these signs, it's highly likely you've been blocked, though some privacy settings can mimic these effects.
To know if someone blocked you on WhatsApp, look for a combination of signs: messages only show one gray tick (sent, not delivered), you can't see their profile photo or online status/last seen, WhatsApp calls fail to connect, and you can't add them to a group, but remember no single sign is definitive, though seeing all of them is a strong indicator.
How to check if someone has blocked you on WhatsApp? Look for multiple signs together: no 'last seen' or 'online', profile photo not updating, messages stay with one grey check, calls don't connect, and you can't add them to groups.
Here are the main signs that someone may have blocked you: You can't see their profile picture or updates. Messages you send show only one gray checkmark, not two. The last seen and online status are missing.
When you block someone, messages, calls, and status updates sent by the contact won't show up on your phone and won't be delivered to you. Your last seen, online, status updates, and any changes made to your profile photo won't be visible to contacts you've blocked.
To know if someone blocked you, watch for calls going straight to voicemail after one ring, texts showing "Not Delivered" (or no read receipts/checkmarks on apps like WhatsApp), and potential changes on social media; the most definitive test is calling from another number, where it rings normally for you but goes to voicemail on your original number, indicating a block.
If a person has blocked you, you will not be able to see their message read confirmation (double blue check mark). You will still be able to see message sent confirmations (single gray check mark). You can't see the contacts' statuses. You don't see updates to a contact's profile photo.
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.
If you could see their WhatsApp profile earlier, but now it's replaced by a blank white avatar, the person may have deleted your number on WhatsApp. Remember that the blank avatar also shows up when someone has blocked your WhatsApp number.
Answer. When sending WhatsApp messages, if a user has blocked your phone number in the WhatsApp app (see below), then your messages will not be delivered. In the Twilio Console or via API, you can view the status for each message you send.
If you text someone who blocked you, they won't receive your text. In most cases, you won't see anything special on your end—no notifications that you've been blocked, and the message won't fail. The text will look like it went through, but the person you're texting won't know you've texted them.
Unblock someone
Tap the contact name or phone number you want to unblock. Tap Unblock {contact} or Unblock {phone number}. You and the sender will now be able to send and receive messages, calls, and status updates.
Only seeing one tick on your WhatsApp message rather than two generally means that your message has left your phone and reached WhatsApp itself, but has not reached the recipient's phone yet. They might be in an area with poor signal (such as on a plane), have their phone turned off, or (maybe) have blocked you.
When someone blocks you on WhatsApp, their status updates will no longer be visible to you. Status updates include photos, videos, and text that disappear after 24 hours. If their updates have suddenly stopped appearing, it could be a sign that you've been added to their blocked contacts.
First things first: people do not receive notice when you block them. As soon as you block someone on iPhone, they lose the ability to text or call you. Except the blocking happens at the level of your device. The person you blocked will not realize you blocked them when they try to call you.
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.
A blocked person can't reach you via text. Technically, they can still send an SMS message to your phone number, and they'll see the regular delivery status at their end, just like with any other texts they send.
Signs you may have been blocked
Here are a few signs that someone may have blocked your number: You don't get a delivery confirmation. If you have an iPhone and text another iPhone but don't see a “Delivered” notification, someone may have blocked you. (Android phones don't automatically show these messages.)
If you can't see the person's profile photo, you are likely blocked on WhatsApp. If you're blocked, you will be unable to see profile updates such as new photos and current status. You'll also be unable to send messages, call them, or add them to group chats.
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.
To know if someone blocked you, watch for calls going straight to voicemail after one ring, texts showing "Not Delivered" (or no read receipts/checkmarks on apps like WhatsApp), and potential changes on social media; the most definitive test is calling from another number, where it rings normally for you but goes to voicemail on your original number, indicating a block.
You've likely been blocked if: Their WhatsApp profile photo is blank/reset to the default graphic and you can't see their status or last seen details, it's a strong sign you've been blocked.
