This service is traditionally accessed by dialing a specific short-code number. 

• Phone Number Lookups: The primary function of directory assistance is to provide callers with phone numbers that they are unable to find on their own. This can include residential, business, and government phone numbers.

• Connection Service: Often, after providing the requested phone number, the directory assistance operator can offer to connect the caller directly to that number.

• Charges for the Service: Most phone companies charge a fee for directory assistance calls. The fee structure can vary based on the provider and the type of service requested.

• Decline in Usage: With the advent of the internet and smartphones, the use of traditional directory assistance services has declined significantly. Most people now find phone numbers using online search engines or digital directories.

While the use of directory assistance has decreased with the rise of digital alternatives, it still remains a useful service for those without internet access or for quick, on-the-go inquiries.
