In print telephone directories, the white pages are literally white pages that display the names, street addresses and phone numbers of residential and business customers.
Publishers typically list names line-by-line in two columns in alphabetical order in A to Z categories by last name followed with complete or initial first names. Readers can only find listings for customers who haven’t opted out of having their names displayed in publicly distributed directories. White pages typically don’t feature any sort of advertising beyond the publisher’s details.
Business white pages differ slightly from residential white pages in that they often display another color along the page edge. Publishers also highlight certain companies with a different ink color or additional details such as office hours and a company’s tag line.
The Yellow pages refer to a phone directory with the details about different businesses. The details included in the directory are phone numbers of an organization, location, and the nature of business that the organization conducts.
Companies can buy space and advertise too within their particular categories. The names on the directory are arranged by category, for instance, Architecture, Attorneys, etc., as opposed to alphabetically by business name.
Yellow Pages carry all the contact information of a company as long it is listed.
On check-caller.com you can leave your feedback about a call number and mark it as safe or unsafe. This information is immediately displayed on the detail page of the number. These specifications are often more useful than the indication of a name.
But check-caller.com combines both: an active community, which lives from the feedback of their users and their help to design the web page and also an actual phone list with over 160.000.000 names and companies.
