Which number is used virtually nationwide by carriers for directory assistance?

• A. 311
• B. 611
• C. 211
• D. 411

Answer: (D)

Directory assistance is the service used to look up phone numbers, and the standard nationwide way to reach it is by dialing 411. Carriers route 411 to a directory assistance operator who can provide a listed phone number or address. The other numbers serve different purposes: 311 is municipal information in many areas, 211 connects you with community or social services, and 611 is for reaching your carrier’s customer service or repair line. That universal purpose makes 411 the best answer.
