How to Check if a Phone Number is on WhatsApp

You can check if a phone number is registered on WhatsApp using either the WhatsApp app or a web browser. Follow the steps below to verify:

Using the WhatsApp App

1. Open the WhatsApp App and go to the Chats screen.

2. Tap the "+" button and select "New Contact."

3. Enter the phone number you want to check.

• If the number is registered on WhatsApp, you’ll see a green checkmark with the message: "This phone number is on WhatsApp."

• If the number is not registered, you’ll see: "This phone number is not on WhatsApp. Invite to WhatsApp."

• If the number is already saved in your contacts, you’ll see a green checkmark with the message: "This phone number is already in your contacts. View contact."

Using a Web Browser (Chrome/Safari)

1. Open your browser and type https://wa.me/ followed by the country code and phone number you want to check. For example, if you're checking the number 12345678, type: https://wa.me/85212345678 (where 852 is the country code for Hong Kong).
2. Press Enter. A prompt will appear saying: "Open this page in WhatsApp?" Tap Open.

• If the phone number is not registered on WhatsApp, you’ll see the message: "The phone number isn’t on WhatsApp."

• If the number is registered, the WhatsApp chat screen will open. You can start a chat with the person (without saving the number) or simply exit the screen.
