How to Find a Cell Phone Number from an Email Address

By Colleen Collins

Perhaps you only have an email address, and would like to have that person's cell phone number as well. Unfortunately, there are no general repositories that contain all known email addresses or cell phone numbers, so to find a cell phone number linked to an email address requires some investigative work on your part. Fortunately, there are multiple free, reverse email look-ups to help in your search. If none of those look-ups provide a number, consider hiring a professional private investigator who specializes in cell phone searches.

Step 1

Send an email. The easiest way to find out if the owner of an email address has a cell phone number is to simply send an email. If you're not sure whose email address it is, introduce yourself and explain your reason for making contact and why you are requesting the cell phone number.

Step 2

Check the email address in Google. Because Google is the most comprehensive public search engine available, use it to conduct a reverse email search. Enter the email address in the Google browser, press the "Search" button, then review every result; these might include websites, blogs or social media sites. For example, if a blog displays that email address, check its text for an associated cell phone number.

Step 3

Run a deep web reverse email search. Pipl is a free, deep web search engine, which means its web crawlers find content more traditional web crawlers miss. Go to, click the "Email" link, enter the email address and press the "Search" button. Pipl displays online sites and documents where that email address displays -- as in Step 2, check the content of those sites and documents for any cell phone numbers linked to that email address.

Step 4

Conduct a search in social networks. Kgbpeople offers a free, comprehensive search in social networks, as well as search engines, online photos and videos and personal profiles. Go to, enter the email address in the "Name:" field at the top of the page, select the country in the pull-down menu and press the "Search" button. Select one of the four tabs at the top of the screen -- Social networks, Search engines, Photo and video, or Personal -- then review the results for a cell phone number associated with that email address.

Step 5

Search all Craigslist ads. Because over 50 million people in the U.S. use Craigslist, it's a handy place to conduct a reverse email search. Go to, enter the email address in the field and press the "Search" button. In the results, review the ads for a cell phone number connected to that email address.
