A phone directory, also known as a telephone directory or telephone book, is a comprehensive listing of telephone subscribers in a specific geographic area, such as a city, region, or country. It typically includes the names, addresses, and phone numbers of individuals, households, and businesses. Phone directories serve as valuable resources for people looking to find contact information for others, connect with businesses, and make phone calls.
They are often organized in alphabetical order, making it easy to look up a person or business by name and find their associated phone number and address. In the digital age, many phone directories have transitioned to online or electronic formats, making them easily accessible via the internet or specialized applications, thus rendering the traditional printed phone book less common.
