Method 2 : Verify WhatsApp Numbers manually
1. Using the WhatsApp App
Step 1: Open WhatsApp
Launch the WhatsApp app on your Android or iPhone.
Step 2: Start a New Chat
Tap the "New Chat" icon (message bubble or plus symbol).
Step 3: Add or Search the Number
Option A: Add the phone number as a new contact with the full international code (e.g., +1, +91, +44).
Option B: Or type the full number directly into the search bar.
Step 4: View the Result
If the number is registered on WhatsApp, you’ll see their profile, online status (if visible), and options to message or call.
If not, you’ll see an “Invite to WhatsApp” option instead.

Cons of Manual WhatsApp Number Checking
One number at a time:You can only check WhatsApp registration for one phone number at a time, making this method slow and impractical for bulk number verification.

Alternative Solutions
To find someone on WhatsApp, you generally need to already have their phone number saved as a contact on your phone. You can then search for them within WhatsApp using that saved contact information. You can't search by name or number on WhatsApp if the number isn't already saved in your contacts.
Here’s how to find someone on WhatsApp:
Open WhatsApp and go to the "Chats" tab.
Tap on the "New Chat" icon (usually a speech bubble icon).
Search for their name or number in the search bar.
Select the contact from the list that appears.
Start a conversation.
If you don't have their number saved as a contact, you'll need to add it to your phone's contacts before you can find them on WhatsApp. If you are in a group chat, you can usually see the participants listed, which may include the person you are looking for. You can also use third-party tools like Truecaller to identify unknown calls and messages on WhatsApp.
