Are you getting annoying calls from an unfamiliar number? Do you need to look up a who is calling you? There are ways to find out who owns a mobile phone number for free and all you have to do is go on the internet.

Here are eight possible ways to search who is calling your phone number.

1. Facebook

Did you realize that you can look for individual on Facebook by entering a phone number? By entering a phone number on the Facebook search bar, you may be able to find the profile of the person to which the number belongs to.

Unfortunately, most people have changed their privacy settings so that people can’t find them on Facebook that way or they don’t add their number to their profile at all.

Additionally, it is not guaranteed that you will get the most up to date, accurate data and that person may not have that number anymore. So even if on the off chance you do find a person’s profile that is connected to the number you researched, that person may not be associated with that phone number anymore.

2. Answering The Phone or Calling Back

Regardless of what the circumstance is, it's never a good idea to answer an unknown phone number or call back on your cell phone. If it’s important, they will leave a voicemail.

Here are a few reasons that you should never pick up the phone when you are not sure whose number it is:
  • It could be a scammer who has perfected the art of being a con artist.
  • It may be a telemarketer, and if you pick up they know your number is an active one and they will put it on their list.
  • It could be an ex or someone who is fixated on you and wants to hear your voice.
  • It could be a predator seeking a victim to prey on.
  • It could be from a one-ring phone scam.

It’s safe to say that it's not the best idea to answer an unknown call because you never know who is on the other end.

4. How to Use Google to Find Phone Numbers

Google used to have a phonebook service, but it was taken down when people started wanting their information removed from the service. Therefore, Google isn’t the best choice for someone to look up another person’s number.

Even on the off-chance that Google has any information in regards to who has been calling you, it may not be reliable or up to date.

5. Research The Area Code

The area code listed on the phone number that keeps calling you may give you more insight into what kind of call it is than you realize. Foreign area codes are most of the time scammers.

Toll-Free numbers like 800 or 844 are usually telemarketers. Always beware of toll-free numbers and calls coming from outside of the US. Also look at this list from Forbes to see the some international area codes that are unsafe.

Additionally, the area code will give insight into where someone lives. In the illustration below, you can see that 5.7 million cell phone numbers start with 917. If you look up that area code from a cell phone number, you will discover that the caller lives in New York City.


This phone number database is built by its users. People share information on a call they receive. If other people have had a call from the number that is contacting you, they can report it on the website for you to view at your leisure.

This method will only work if the number is calling other people and at least one other person has reported the number to you.

Additionally, even if they report the number they might not have any more information than you already have on the number.


Pipl does have a free phone search, but it doesn’t seem to have the most accurate, up-to-date data.

When entering my cell phone number, I was given old information about myself including my maiden name, (but not my married name) an old landline number (which was disconnected a few years back), a former address, and they had my age wrong by 16 years.


Whitepages claims to be free, but after it compiled my report, the website asked me to pay for the information is found on the number I provided.

It did not offer me the name, or even address of the person who owned the number. Something it did offer me for free was that it was a low-risk number and the general area of the owner’s location. I knew at that point that the number I searched was low risk, so that information was valuable. However, any other information that I wanted I had to pay for.
