How to Find People on WhatsApp Without Knowing Their Number

Do you need to find someone on WhatsApp but do not know their cell phone number? Well, truth be told, finding a person on WhatsApp is a bit different from seeing a person on Facebook or Instagram. Because of privacy and security measures, this instant messaging app doesn’t allow you to search for others directly on its platform unless you already have their phone number or someone from your mutual friends or connections shares the necessary WhatsApp account with you.

In this review, we will explain how to find people on WhatsApp and the easiest methods for achieving this purpose.

How to Find People on WhatsApp?

Before we start, it is necessary to point out that finding a person on WhatsApp if you don’t know their number is different on Android and iOS-operated devices. However, there are a few tricks that you can start with, regardless of your cell phone’s OS.

Look Through Group Chats

Are you and the target person members of a specific WhatsApp group? If the answer is “yes”, you can use it to find their cell phone number there. How to find people on WhatsApp group chat?

  1. Open the WhatsApp app and navigate to the group where you both participate. To simplify the process, kindly tap the group name at the top.
  2. Then scroll down through the list of participants till you find the contact you are searching for.
  3. Tap their name and view their contact details (note: it will only be possible if their privacy settings allow it).

Check Their Facebook Profile

Want to message someone on WhatsApp but don’t have their number? Try checking their Facebook profile. If you’re lucky, their cell phone number might be public.

Here’s how to do it:

  1. Open Facebook and search for the person.
  2. Click their profile, then go to “About” and “Contact and basic info”.
  3. It’ll show up there if they’ve shared their number.

Try People Finder Tools

Need a phone number? Try tools like True People Search, PublicRecord.com, or BeenVerified. Enter the person’s name or address, and you’ll get a list of possible matches. Find the right one, click for details, and you might get their number. You can then use it to search for them on WhatsApp too.

Use “Invite to WhatsApp” Feature

If you have the target person’s number in your contacts and want to know whether they use the same number on WhatsApp, there is a simple way to check it. How?

  1. Go to your WhatsApp contact book.
  2. Search for a desired contact.
  3. If they do not have WhatsApp on that number, you will see an Invite to WhatsApp option when trying to message them.

Ask Your Friend to Help

Do you have mutual friends? Then it can be handy. Simply ask your friend to share their contact information with you. It’s as easy as eating a bar of chocolate. However, if you do not want them to ask you why you need this phone number, you should use alternative methods as described below.
