How to Search for the Owner of a Phone Number

By Shara JJ Cooper

You may want to find out the owner of a phone number for a variety of reasons. Maybe they called your house and didn't leave a message. Or maybe someone gave you their number but you can't remember their name. Whatever the reason, you should be able to find the owner of a phone number either by doing an online search or using a resource at the library.

Search Online

Step 1

Find the last phone number of someone who called you by pressing *69 on your phone after you receive the call. This only works for the last call that came into your phone line and you will need to do it on a touch-tone phone. On a rotary phone you can dial 1169. Different phone companies have different phone codes but *69 is the most common one. If you need to find the phone number of someone who called you previously you can call your service provider. They should be able to provide you a list of the numbers that called your line.

Step 2

Open a browser window on your computer and go to www.yellowpages.com. Select "find a person > by phone number." Enter the phone number. You will need to know the area code or region in order to find the phone number.

Step 3

Click "find" and wait for the website to finish loading the new information. If the phone number is listed it will show you the name of the owner as it is listed in their registry. Depending on how much information is available, you may also see their address, service provider and whether or not the phone number is a land line or cell.

Library Search

Step 1

Call your library and see if they have a "Criss Cross" directory. This book is used to search people by phone number or address. It was used before the information became so readily online.

Step 2

Go to your library and find the "Criss Cross" directory. This directory is available for reference use only so you will not be able to leave the library with it.

Step 3

Search for the phone number, first using the area code, then the prefix and finally the last four numbers to find the owner's name. These directories are not updated as regularly as online databases so this will only be accurate if the number is from someone who has an established number.

Tips & Warnings

  • If you can't find out who owns a phone number you can search the area code and prefix (middle three numbers) to find out what area they are calling from. Many online databases are available with this information. Depending on the area you may even be able to narrow the caller down to a few blocks.
  • You can add a caller ID service to your phone number that will allow you see the identity of the people who call you before you answer the phone.
