"What's his phone number again?" How to find people with online directories.

In these days of cell-phones and unlisted phone numbers, it can be difficult to find contact information for people. The first thing to realize about searches like this is that they take time: you may have to check multiple sources and try contacting multiple phone numbers or addresses. Here is a list of directories and websites that you can use to search for people; you should search in as many of them as possible and try different spellings of names.

(Note: some websites will try to give you a little bit of free information and then ask you to pay before they show you more. Keep in mind that the additional information might or might not be what you need.)

  • ReferenceUSA: A Multnomah County Library-provided resource. Use the "U.S. Standard White Pages" section to search a database of U.S. residents. The data is not always up-to-date.
  • Dex Knows: A phone and address directory for people and businesses. Can look up by name, phone number, or address.
  • Yahoo! People Search: A directory to people which can be searched by name or phone number.
  • Switchboard: A nationwide business and residential directory.
  • Canada 411: A directory to find people and businesses in Canada.
  • Pipl: A website that searches various directories and websites to try to find people. Many of the results will only give a little bit of information for free, but it can still be useful.
  • Facebook: A social networking website where users create profiles. Users can choose whether they want their profiles to be findable via this search page.

Good luck! And if you get stuck, please contact a librarian and we'll be happy to help!
