It might take some investigating, but it's possible to find a phone number using an email address.

Maybe the only contact information you have for a person is an email address, but you'd like that person's phone number, too. You can be straightforward and simply send an email message to that person requesting his phone number, or you can conduct some reverse email searches, and with a little investigative work, see if a phone number is linked to that email address.


Step 1

Send an email message. The easiest, most straightforward way to find the phone number is to simply send an email and ask. If it's an email address for someone you don't know well, politely re-introduce yourself and explain why you'd like that person's phone number.

Step 2

Conduct a deep web search. The web crawlers of a deep web search engine find information that general-purpose search engines miss. Pipl, a deep web search engine, searches websites, blogs, online documents, member directories, personal profiles and more. Go to, click the "Email" link, enter the email address, and press the "Search" button. Any instances of that email address display as links--click each link and review the contents for a phone number associated with that email address.


Step 3

Search social networking sites. One free, comprehensive social networking search is YoName, which lets you search in 26 social networking sites at one time. It's possible a person might list her email address, as well as her phone number, in such a site. Go to, select the "People Search" button in the middle of the web page, enter the email address, and press the "Yo!" button. This search involves some investigation (for example, if the email address displays in a MySpace site, click on that link and search that site for a phone number connected to that email address).


Step 4

Search all Craigslist ads. Sometimes people list their email addresses and phone numbers in Craigslist ads. To conduct a comprehensive, free search of all Craiglist ads, go to, enter the email address, press the "Search" button, and review the results. If that email address displays in an ad, click on that link and review the ad for a phone number.



Step 5

Conduct a news search. Sometimes a media article might contain contact information (email address, phone number) for a person, so it's useful to conduct a reverse email search in a media search engine such as Mool, which searches 4,500 broadcast media, newspapers and national magazine websites. Go to, click the "Media" link toward the bottom of the screen, enter the email address, and press the "Search" button. If that email address appears in a media link (such as in an online newspaper article), click that link and review the information for a phone number associated with that email address.


Step 6

Hire a private investigator. Investigators have resources, including proprietary databases, where they can conduct further research to find possible phone numbers associated with an email address. To find a qualified investigator, contact the professional private investigators association in your state. To find state associations, so to, and under "PI Links" in the top blue bar, select "State Associations–USA."
