A telephone directory is a printed or digital listing of telephone numbers and associated contact information for individuals and businesses. It typically includes names, addresses, and phone numbers, organized alphabetically or by category. Telephone directories help people find and connect with others easily. In the past, physical telephone directories were commonly distributed to households, but with the rise of the internet, many people now use online directories. These digital platforms often provide additional features, such as maps and user reviews, making it easier to locate services or individuals, like plumbers or restaurants.
