Connecticut's Department of Administrative Services offers a list of links for free telephone directory assistance resources that can be accessed online or by telephone. The online resources include 411, Yellowbook, Whitepages and Anywho. The free version of 411, 1-800-373-3411, provides the main free telephone resource for free telephone directory assistance.
The 411 website offers a free nationwide people and business information look up and reverse phone number and address look up. Yellowbook provides nationwide business category and business and people phone number look up. Whitepages specializes in people look up services and gives nationwide people and business phone number look up and phone number and address reversal look up services.
Anywho utilizes both the Yellow Pages and the White Pages services in providing people and business, phone number reversal and area code and zip code look up services. This service also includes a map search and a directions provider through the Yellow Pages service. Other sites, such as Superpages.com, offer a few of the same services but do not provide all-in-one look up services. Many of the original free telephone resources for free telephone directory assistance, including the original 411, are now available online, which leaves very few remaining free dial up telephone assistance services.
