Part 3: How to Check If a Number is on WhatsApp? (Other 5 Ways)

While FamiGuard WhatsApp Last Seen offers a comprehensive and efficient solution for WhatsApp number verification, there are alternative methods that can be employed to determine if a number is active on WhatsApp. These methods vary in their approach and effectiveness, catering to different scenarios and user preferences.

1. Sending Messages

One of the most straightforward methods to check if a number is active on WhatsApp is by sending a message to that number. If the message is successfully delivered, it indicates that the number is associated with an active WhatsApp account. However, if the message fails to deliver, it could signify that the user has either updated their contact information or has been inactive on WhatsApp for an extended period.

2. Adding the Number as a New Contact

Another viable method involves attempting to add the number as a new contact within the WhatsApp application. To do this, follow these steps:

Step 1. Open WhatsApp and navigate to the "Chats" tab.

Step 2. Tap on the + icon at the top-right corner > "New contact".

Step 3. Enter the phone number you wish to verify.

If the number is associated with an active WhatsApp account, you will see a green checkmark and a message confirming that "This phone number is on WhatsApp".

Conversely, if the number is not registered on the platform, the app will display a message indicating that "This phone number isn't on WhatsApp. Invite to WhatsApp".

3. Checking the Last Seen Status

For numbers already added to your contacts, you can observe the "Last Seen" status in their respective chat windows. If the "Last Seen" information is visible, it indicates recent activity on the WhatsApp account associated with that number. However, it's important to note that some users may have chosen to hide their "Last Seen" status, rendering this method ineffective in those cases.

4. Using Safari

You can leverage the Safari browser to check if a number is active on WhatsApp. Simply open Safari and enter the following URL, replacing the "XXXXXXXXXX" with the phone number you wish to verify (including the country code):

https://wa.me/XXXXXXXXXX

If the number is associated with an active WhatsApp account, Safari will prompt you to open the WhatsApp app and initiate a chat with that contact. However, if the number is not registered on WhatsApp, you will receive an error message indicating that the link is invalid.

5. Making a WhatsApp Call

Another method to check if a number is active on WhatsApp is trying to make a voice or video call to the number. If the call status appears as "Ringing", it suggests that the user is currently active on WhatsApp or has an active internet connection. In contrast, if the status displays as "Contacting", it may indicate that the user is inactive or has not been using WhatsApp for some time.
