Quick Answer
Yes, blocking someone’s phone number on an iPhone will block them on WhatsApp as well. WhatsApp uses your phone’s contacts and numbers, so blocking a number in your iPhone settings will carry over to WhatsApp automatically.
Detailed Answer
When you block a phone number in your iPhone settings, it prevents all calls, messages, and notifications from that number across all apps. This includes WhatsApp, because WhatsApp relies on your phone’s contacts and numbers to connect you with your contacts on the app.
So if you block or delete a phone number in your iPhone contacts or settings, that person will also be blocked or deleted from WhatsApp automatically. They will no longer be able to call or message you on WhatsApp.
Here are some more details on how blocking on iPhone and WhatsApp works:
Blocking on iPhone
To block a number on iPhone:
1. Go to Settings > Phone > Blocked Contacts
2. Tap Add New and enter the phone number you want to block
3. Tap Block Contact when prompted
This will block the number from calling, texting, or contacting you on any app on your iPhone.
Blocking on WhatsApp
To block someone on WhatsApp specifically:
1. Open your WhatsApp chat with the person
2. Tap their name at the top of the chat window
3. Scroll down and tap Block Contact
This will only block them on WhatsApp, not on your entire iPhone.
If you block their phone number on your iPhone, they will also be blocked automatically on WhatsApp. The reverse is not true – blocking only on WhatsApp will not block their number system-wide on your iPhone.
Unblocking
If you decide to unblock someone:
– On iPhone: Go to Settings > Phone > Blocked Contacts and delete their number
– On WhatsApp: Go to WhatsApp Settings > Account > Privacy > Blocked Contacts and unblock them
Unblocking their number on your iPhone will also unblock them on WhatsApp.
Why Blocking on iPhone Affects WhatsApp
Blocking a phone number on your iPhone blocks it across all apps because of how WhatsApp integrates with your phone’s systems:
– WhatsApp uses your phone’s contacts and numbers to connect you with others using the app.
– When you first set up WhatsApp, it accesses and uploads your phone’s contacts to match you with other WhatsApp users.
– WhatsApp does not store contacts separately – it relies on your phone’s contacts app and system level blocking.
So if you block a number in your iPhone settings, WhatsApp cannot access it anymore to match with users, and will show that user as blocked on WhatsApp as well.
Does Blocking Delete WhatsApp Messages?
Blocking or deleting a contact on iPhone or WhatsApp will not automatically delete your previous WhatsApp messages and chat history with that person.
Your existing WhatsApp chats and message history will still be stored in WhatsApp when you block someone.
To delete past WhatsApp messages and conversations, you need to clear your chat history with that contact before blocking them.
Here’s how to delete WhatsApp messages with someone before blocking:
1. Open your WhatsApp chat with the contact
2. Tap and hold on a message
3. Tap Delete at the top
4. Choose to delete all messages
This will clear your message history with this contact, then you can block them and they won’t be able to message you again.
How to Know if You’re Blocked on WhatsApp
If someone has blocked you on WhatsApp, here are some signs you may notice:
– Your messages to them will remain undelivered and unread
– You cannot see their profile photo or last seen status
– Any calls you make to them on WhatsApp will not go through
– You’ll be removed from any WhatsApp groups you had in common
Being blocked on WhatsApp essentially removes you from the contact’s account and prevents any interactions.
The other person will not get any sort of notification that you are blocked. It will seem like they have deleted you from their contacts.
Pros of Blocking on iPhone vs. WhatsApp
Here are some pros of blocking directly on your iPhone versus only blocking on WhatsApp:
| Blocking on iPhone | Blocking only on WhatsApp |
|---|---|
| Blocks the person system-wide across all apps | Only blocks the person on WhatsApp itself |
| More effective at preventing unwanted contact | Person could still contact you via calls, texts, other apps |
| Block carries over if you switch phones | Block only applies on that device’s WhatsApp |
In most cases, blocking directly on your iPhone is more thorough and prevents the person from contacting you across all communication channels.
But in some cases, you may only want to block someone on WhatsApp specifically without affecting your other communication with them. This allows for more granular control.
Recovering Blocked Messages on WhatsApp
If you blocked someone on WhatsApp and want to recover your previous chat history and messages with that person, here are some options:
– **Unblock the contact** – This will restore your chat history with them so you can view past messages.
– **Use a WhatsApp backup** – WhatsApp backups saved to iCloud or Google Drive will store your chat history, even with blocked contacts. You can restore from a backup to view blocked messages.
– **Use third-party tools** – Some tools like iMyFone D-Back can extract WhatsApp data from phone backups and recover deleted and blocked messages.
– **Retrieve from phone files (advanced)** – On Android devices, WhatsApp stores chat histories in internal storage files that can sometimes be extracted even if the contact is blocked.
But keep in mind – if you deleted the chat history before blocking the contact, those messages may be permanently deleted and irrecoverable. Blocking alone does not delete messages retroactively.
Questions People Also Ask
Does blocking on WhatsApp delete the chat?
No, blocking a contact on WhatsApp does not itself delete your chat history or past messages with that person. Your WhatsApp messages with them will still be stored in your chats, but you will no longer receive new messages after blocking them.
Can I retrieve blocked WhatsApp messages?
Yes, you can retrieve blocked WhatsApp messages by unblocking the contact to access your chat history, using a third-party data recovery tool, or extracting WhatsApp data files directly if you have an Android device. Past messages are recoverable if not manually deleted before blocking.
Does WhatsApp notify when you’re blocked?
No, WhatsApp does not directly notify you if you’ve been blocked by someone. But you’ll see signs like messages remaining undelivered, profile photo gone, and calls not going through. The block is invisible from the other user’s end.
Can you tell if someone blocked you on iPhone?
Yes, if someone blocked your number on their iPhone, you’ll get an automated message saying your messages are not delivered, calls go straight to voicemail, etc. The main signs of being blocked on iPhone are failed calls/texts and iMessages not turning blue.
Will blocking someone on iPhone remove chat history?
No, blocking a number on your iPhone will not automatically or retroactively delete your chat history or messages with that person on WhatsApp, iMessage, or other platforms. The chat history remains intact unless manually deleted.
Conclusion
In summary, blocking a phone number on your iPhone settings will carry over to block that person on WhatsApp as well. This is because WhatsApp relies on your phone’s contacts and blocking capabilities. Blocking in your iPhone settings provides a system-wide block across all apps and communication channels. Blocking only on WhatsApp just affects that app specifically. Your existing WhatsApp chat history will not be deleted when blocking someone, so past messages can still be recovered if needed.
