How to Find a Phone Number in the USA

In the old days, if you wanted to look up a person's phone number, you had to know what city they lived in so you could find the correct telephone book. When Internet white pages came along, it was still necessary to select the individual's state before you could search. But now there are several online resources that allow you to search for a person anywhere in the U.S., even without knowing which city or state they live in.

...
Online telephone directories can search the entire country.

Step

Search for the person's name at Superpages.com. Enter the first and last name in the respective search fields, leave the city and zip code fields blank, and select "All States" in the state pull-down menu.

Step

Unlike most other online phone books, Superpages has the option to search all states at once, so a nationwide search for a phone number takes just seconds.

Step

Search at Jigsaw.com for a workplace phone number by entering the person's name in the search box, and clicking the magnifying glass icon.

Step

Jigsaw is a business contacts database that includes millions of workplace listings nationwide. Name, title, company and address information can be retrieved at no charge, but there is a fee to retrieve phone number and email information.

Step

Search for the person's name at Intelius.com by entering the first and last name in the respective search fields and selecting "All States" in the state field. As with listings at Jigsaw, Intelius returns preliminary information at no charge, but there is a fee to retrieve a full listing with a phone number.
