One of the most significant limitations of WhatsApp is its inability to allow users to check whether a specific phone number is registered for the service unless that phone number or contact is saved in the iPhone's address book.
However, the good news is, starting from WhatsApp version 2.19.30, users can now search and check any phone number's registration on WhatsApp. In the article below, Mytour will guide you on how to check if a phone number is registered on WhatsApp.
How to Check if a Phone Number is Registered on WhatsApp
Follow the steps below to verify if any phone number is registered on WhatsApp:
Step 1: Open the WhatsApp application on your iPhone.
If you haven't installed WhatsApp yet, you can access it here to download and install the app: Download WhatsApp
Step 2: Find and select Chats in the tab area located at the bottom corner of the screen.
Step 3: Select the New Chat button located at the top right corner as shown in the image below.
Step 4: Select New Contact near the top corner of the screen as shown in the image below.
Step 5: Enter the complete phone number along with the country code to check if that phone number is registered for WhatsApp service.
Step 6: Select Cancel to exit this option or add the name and other details, then press Save to add the new contact.
If detailed information about this user is already stored in the address book app, a message will appear on the screen stating that the contact is already in the address book.
