How to check if a phone number is on WhatsApp

One of the biggest annoyances with WhatsApp used to be that you couldn’t see whether a particular phone number was registered with the service unless it was saved in the Contacts app on your iPhone. That changed with WhatsApp version 2.19.30. Now you can easily see if any phone number is on WhatsApp before messaging it, and iDB shows you how.

This feature is handy when you want to see if a person whose phone number you know is using WhatsApp or not. Before WhatsApp 2.19.30, you had to first save a number in the Contacts app for WhatsApp to be able to determine if it’s on the service.

So the next time you meet someone and manage to get their phone number, you can check if they’re on WhatsApp before saving them as a contact. Follow along with us as we show you how.

1) Open WhatsApp and be on the Chats screen. 2) Tap the new chat button from the top-right. 3) Tap New Contact. New Contact in WhatsApp on iPhone 4) Type or paste the full phone number you want to check.
