How to understand that a person has changed their phone number in WhatsApp - in detail?
To determine if someone has changed their phone number on WhatsApp, you can look out for several indicators:
- Updated Contact Information: If the contact details of a person have been updated recently in your phone's address book, it may indicate that they have changed their phone number. Check the last modified date to see if it coincides with any recent messages or calls from this person.
- New Number Notification: WhatsApp sometimes sends a notification indicating that the contact has changed their phone number. This message typically appears at the top of the chat window and mentions the new number. Pay attention to these notifications, as they provide direct evidence of a number change.
- Changed Profile Picture or Status: A sudden change in profile picture, status, or other visual elements on WhatsApp can sometimes hint at a number change. People often update their profiles when setting up a new phone or account.
- Unusual Chat Behavior: If you notice any unusual behavior in the chat, such as messages appearing out of order or delayed delivery times, it could suggest that the person has switched to a different number. WhatsApp may need some time to sync messages with the new contact information.
- Group Message Changes: In group chats, if you see a change in how a participant's name is displayed (e.g., from "John Doe" to "New Number"), it might indicate that John has changed his phone number. Group chat members may also receive notifications about the number change.
- Verification Codes: If someone sends you verification codes or messages related to setting up a new WhatsApp account, it is a strong sign that they have switched to a new phone number.
By carefully observing these signs, you can determine if a person has changed their phone number on WhatsApp and take appropriate action, such as updating your contacts list.
