411.com and Whitepages.com are two domains for online directories owned by Seattle-based company Whitepages, Inc. These websites function identically, only differing in name and aesthetics. Whitepages.com also offers a few more features, and most tabs on 411.com link to a page on Whitepages.com.
The only major difference between the sites is their color schemes. Whitepages displays names in gray and white, while 411 displays them in turquoise. The company maintains other domains online and also develops cell phone apps, including a well-known Caller ID app for Android and an app version of its main website.
Both websites contain identical search features. Users can search the directories by entering a name, business name or address, which brings up a list of relevant entries. Users can also search phone numbers to identify a caller. Whitepages offers users access to its paid service Whitepages Pro, which helps businesses avoid fraud, prevent automatic callers and identify callers more easily.
Alex Algard founded Whitepages in 1996. As of 2015, it is the largest database of Americans' contact information and contains the phone numbers and addresses of over 90 percent of the country's adult population. People can contact Whitepages to have their information taken out of its directories.
