Phone directories encompassing the Calgary, Alberta area are available through a number of online resources such as Canada411.ca and Whitepages.ca. Users may search these websites using a person's first and last name along with their city, province or postal code to determine the individual's phone number.
These online directories also provide reverse look-up services, allowing an individual to search a phone number to determine the identity of a caller. In many cases, these directories also provide individuals' and businesses' addresses. Moreover, they often have connections with sites such as Ancestry.ca, which provide birth, death, marriage and divorce records.
In addition to Web delivery, Yellow Pages directories are available as a mobile application for Apple, Android, Windows and BlackBerry devices.
In 2010, Yellow Pages, the main producer of Canadian phone books, ceased distribution of the print version of its White Pages residential directories in major cities, including Calgary. As of 2015, the company has begun to scale back its Yellow Pages commercial directory distribution, making both copies available only upon request to residents in most areas. This came after a period of opt-out delivery, during which the company had focused on the expansion of its online presence as a digital marketing company.
