How To Find Who Called You | 5 Tricks

There are some ways to find out who called you, or at least have some idea who might be behind the unknown number. These methods include using search engines, web tools, or mobile apps. Let’s take a look.

1. Google the Number

Like every other solution these days, the quickest option to check for an unknown number would be to Google it. Just type the number in the search bar, or try different variants with or without the country code and the country’s name.

Here are some examples:

  • “+12025886500”
  • “12025886500”
  • “12025886500 united states”
  • “12025886500 us number”

If you are lucky, you may be able to find some information related to the unknown number – a name, address, or perhaps the associated social media account.

The best part about this method is that it’s straightforward and free; if this doesn’t work out it won’t cost you anything.

2. Use a Reverse Phone Lookup Site

So Google didn’t help you find the unknown number. No worries, there are many reverse phone lookup sites that can help you find the whereabouts of an unknown number. Most of them are free to use too!

Just enter the required number, and if there’s a match, the site will give you the related information.

Here are some of the best reverse phone lookup sites out there.

3. Use a Mobile App

You can also find out who’s calling you from an unknown number using mobile apps. Here are a few for your reference:


Trapcall lets you know who is behind that blocked, marked, or unknown number calling you. You can get information about the caller’s identity to take appropriate action.

Reverse Lookup

The Reverse Lookup app can perform a search on any number to help you know its identity. You can know about the caller’s ID, country, carrier, ZIP code, and phone type, among others.

For now, however, you can only look up numbers from Canada and US.


Whoscall is a caller ID lookup app to help identify unknown numbers and distinguish them from verified numbers. You can also block spam callers and telemarketing calls through this app.

This app is available for both iOS and Android.

4. Add as contact, and search on chat apps

Another way to find out who the unknown caller is to add them to your contacts and search for them through messaging apps on your phone.

To do that, save the unknown number as a contact in your phone and give it a random name like “unknown caller 1” or “who called me”, etc.

Now go to your instant messaging app like WhatsApp or Telegram. If they are using the said app, you might be able to see the contact’s name and see their profile picture on the app.

That might throw you a clue who just called you, whether it’s a friend whose contact you might have accidentally deleted or just some random person.

5. Send a text message to the person

If everything else fails and you are still determined to find the identity of the person behind the unknown number, then you can send a text message to the caller.

Before sending a text message to the unknown number, here are a few things you should consider:

  • Be direct but polite – A direct but polite message like “Sorry I missed the call. Who is this?” will help you get to the bottom of things, if the unknown caller replies, that is.
  • Do not reveal yourself first – It’s wise not to reveal your name (who you are) or send photos of yourself before figuring out who’s behind the unknown call. Instead of telling them who you are right away, find out about the one who’s calling you, and only reveal yourself if you actually know the person.
