How To: Reverse Check a Phone Number

Reverse Check a Phone Number

Prank Calls, Masked Numbers

Who is calling your phone or your child's? Pranksters use a lot of tricks to make sure they can get on your nerves. Being able to trace prank calls is important because you're not going to learn much from your Caller ID, since most prank callers use an unlisted number - such as, a cell phone number. Many also use special code *67 to mask the number so your Caller ID will show "Blocked Number" or "Private Number".

There are a lot of mild cases of so-called phone bullying which can be easily handled by using the steps described below. But if things turn to the worse, like in the case of this Washington's family, you may end being one on one with the bullies and even the police won't be able to help you track them down.

Step 1 Check the Number's Originis

If the number that keeps calling you pops up on your Caller ID, you can check its registered location, service provider and line type by doing a phone reverse lookup. To further find out to whom the number may belong, you can type it into Google, Facebook, public Yellow Pages. You can use a few private directories to carry out a mini investigation on the phone owner. Debt collectors, telemarketers and solicitors usually call from toll free numbers and they call many people - not just you, so someone somewhere has already posted information about that number. Sites such as and WhoCalled are two great complaint boards containing many land line numbers of pesky callers.


Private reverse directories do charge access fees but most of them operate full refund guarantees if they cannot locate any information about an unpublished number.

Step 2 Take a Different Route

If the above step produced no results, you are ready to take another action - contact the police or a private detective. In the case of sensitive issues or mild pranks, you may feel like you don't want to engage the police in your situation so a better alternative is to contact a private investigation agency. While fees are usually high and vary in the range of $50-$100, there is a higher chance of the number being traced accurately through the agency's connections with law enforcement. More serious cases which especially involve underage children, have to be reported to the police.

Step 3 Unmasking the Number

In most cases pranksters go long ways to block their outgoing numbers so you do not have any information at all about the call. They also use computer generated voice to make sure you do not get any clue about the person who is behind this. Unblocking the number is possible in two ways. One way to trace phone calls is by using a service provided by the majority of telephone providers. The service, known as Call Trace, is easy to use. When you receive a prank call, you immediately hang up on the caller. After a minute, pick the receiver back up to make sure the line is clear (you'll hear the dial tone again), then press *57. 

One problem with this approach is the number or name of the caller won't be given to you. Even though the prankster has violated your privacy and the peacefulness of your home, the telephone provider is not allowed to violate their privacy by letting you know who the culprit is. If the calls persist, the provider will turn over the information to the police but never to you. Also, this method may not always work for cell phones.

Telephone companies offer another service known as Last Call Return. When you get a call, you can hit *69 and you'll get the last number that called your phone. You can then use phone reverse search to track down the caller and his or her address. This method, as well, may not always work for cell phone numbers.

If you use a cell phone, try this little trick. Log on to your cell phone web account that lists all the numbers that called your mobile phone. Blocked numbers often appear in these records unmasked. So, by checking the records against the exact time when you received the call from an unknown number, you may well see the number that appeared as Blocked on your Caller ID.

You can also try toll free number forwarding which allows to unblock blocked numbers via forwarding calls to a toll free number. The working trick here is that numbers cannot be masked when calling a toll free number. You can set the forwarding yourself by acquiring a cheap toll free number or you can use a service like TrapCall to do the job for you.


  • "Phone spoofing is the practice of causing the telephone network to display a number on the recipient's Caller ID that is not that of the actual originating station (sometimes the number may appear to be your own)." Wikipedia. This means that your phone has been hacked and you need to change it and take precautionary measures. A hacker could have broken into your cell phone account online or hacked the software of the cell phone provider to spoof your phone. You will need to change your phone, get a new number and account and keep it confidential. Also take the old phone to the police to check.

i am so confused please answer my quest...i got a call from a number which is with me is it possible/

someone used your number as their ANI or caller id.

I got a call with no number. The ID said Anonymous and under it was UUU. I have no idea why this worries me except that the young american person who called (I'm american too) said, "You don't recognize my voice anymore, grandma?"

Naturally this will eat at me.. but there are two grandmas here, myself and my mother. Between us we have only 3 grandsons. Mine is sleeping, or was before I knocked on his door asking if he pranked me, and my mothers - 1 in is prison, the other is older and never calls. This was a young guy.. sounded either sick, drugged up, but he wasn't laughing or anything. He kept saying, "You don't recognize your grandsons voice?

I said "this is XXX (my first name) and, what is yours?" I then heard two beeps - like someone pressed the wrong keys on a phone - and the person hung up. This is driving me insane.

But if it was my mom's grandson he would have known my name and realized he had the wrong grandma.

Yet he got under my skin and I will admit I am a tiny bit freaked out - wondering - what if my moms prisoner grandson got a cell somehow (it happens in prisons) and was trying to communicate? Logic dictates that he'd have known it was me...

Yet I am pretty upset - and worried.

If this was a prank call - it's one of the best i have ever seen. thankfully this is a landline he called on so I'm not worried about the possibility mentioned above about hacking into a cell.

Anyway.......... any ideas? :-/

I'm being harassed by a group or person that is spoofing people's numbers to call me.

Is there a way to trace or hack trace with Kali Linux the original number being used?

Perhaps even hacking the spoofcard companies trying to find a match to these numbers in their database?

you need help with hacking via kali-linux? other os will work too

never fear, zer0 is here

first step is to go on your linux distro and download phoneinfoga, like so:

run these commands in order:

curl -sSL | bash

sudo install ./phoneinfoga /usr/local/bin/phoneinfoga

./phoneinfoga version

once phoneinfoga is installed, you should be good from there (as long as you're familiar with linux)

hope i could help.
