4 Ways to Check if A Phone Number is On WhatsApp or Not

Looking to know whether a contact is on WhatsApp or not?

This guide is for you.

I have shared three ways to check if a contact is on WhatsApp or not.

#1 method is a semi-automatic way to check if a contact is on WhatsApp or not.

#2 method is fully automatic.

#3 method is manual, which you might already know!

Let’s get started!

Method #1: Know whether A Phone Number is on WhatsApp.

This method requires you to install a Freemium chrome extension called WA Web Plus.

WA Web Plus chrome extension works with WhatsApp web. You might have to connect your WhatsApp with WhatsApp web.

All you have to do is,

Log into your WhatsApp web account.

Open the WA Web Plus chrome extension.

And you can start using WA Web Plus. You don’t even need to sign up to use WA Web Plus.

Step 1: Search for WA Web Plus Extension on Google

The very first result will show the WA Web Plus chrome extension.

Click on it and check if the extension is from WAWebPlus.com

Install it once it’s installed. Pin the WA Web Plus extension.

Step 2: Log in to your WhatsApp web account.

Step 3: Click on the WA Web Plus chrome extension. Go to Business Tools >> Click on Broadcast.

Verify if a contact is on WhatsApp or not

After that, you’ll see Select Target Contact. Under this section, you’ll see “Import From List.”

Click on it and paste the number that you want to check.

Make sure you add the prefix 91 with the number.

+91 is India’s dialing code. For example, if the number is 9673402844

After adding the prefix 91, it will look like 919673402844

It’s a random number. Don’t think of calling me. 🙂

Step 4: Tick the verify button. And WA Web Plus will remove the contacts if it is not on WhatsApp.

As you can see, this number is available on WhatsApp. By the way, I randomly created this number. 🙂

You can use this semi-automatic method to check thousands of contacts and verify if it’s on WhatsApp or not.

Method #2: A fully automated way to know if a contact is on WhatsApp

This method automatically lets you know if a phone number is on WhatsApp. To use this method, you would need access to some tools.

1) Pabbly Connect

2) 360 Dialog

3) Google Sheets

This method is for businesses who want to automatically check and segregate the contact if it is on WhatsApp or not.

Watch this video to understand the workflow.

An overview of this workflow:

1. Data will be sent from Google sheets to 360 Dialog. This will happen through Pabbly Connect software.

2. Then the number is available on WhatsApp or not that data will be sent back to Google sheets

3. 360 Dialog will verify the number.

With the help of this automation, you can verify thousands of numbers.

This method is recommended for businesses that have a large database of contacts and don’t know if the contact is on WhatsApp or not. If you have a business and want to do WhatsApp Marketing. Read my guide on WhatsApp Marketing in 2022

Let’s move on to the manual method.

Method #3: The manual way

This method you might already know. It’s a basic method.


This is the link. When you click on it, you can message the person on WhatsApp if the number is on WhatsApp.

https://wa.me/(Add your number here)?text=hello

See the example above.

The link will be the same; all you have to do is, change the number you want to check.

Ensure you include a dialling code in the prefix of the number.

91 is India’s dialling code. After that, you can type in the number.

Once you’re done, copy the link and paste it into your browser search box.

If the number is on WhatsApp, you’ll be able to message. Else it will give you an error like “The Phone Number is Invalid.”

This method you might already know.

Step 1: Save the contact in your phone

Step 2: Open WhatsApp
