AnyWho users can obtain cellphone numbers using the website's White Pages functionality that allows users to search for an individual person using a name or address. The AnyWho White Pages website keeps a database of individuals and their phone numbers, both cellphone and landline numbers, from the United States. As of 2015, information found on AnyWho's White Pages tool is provided by Intelius, Inc.
All of the Intelius, Inc. information that makes up the White Pages database are marked as either Publicly Available Information, Commercial Records and Public Records. The AnyWho website also states that none of the information found on its White Pages database are taken from billing records kept by AT&T.
Individuals can request for their information to be removed from the White Pages by either contacting their local phone company to obtain an unpublished telephone number or by following the AnyWho Listing Removal instructions. Once a person fills out the removal request, AnyWho then proceeds to submit the request for data removal.
In addition to its White Pages functionality, AnyWho also provides users with a Yellow Pages service that allows them to find a listed business. Businesses that need to either remove or update their listing are directed to contact YP.com.
