Which number is associated with local exchange carriers for business office use?

• A. 811
• B. 911
• C. 411
• D. 711

Answer: (A)

Special-purpose numbers connect you to services that support safe and efficient telecommunications work. The 8-1-1 number is used to reach the one-call utility location system. When a business plans digging, calling 8-1-1 prompts participating utilities to mark underground lines (such as gas, electric, water, and telecom) before work begins. This coordination through local exchange carriers helps prevent damaging lines, outages, and injuries, which is essential for any job site or facility project. The other numbers serve different functions: 911 is for emergencies, 411 is directory assistance, and 711 connects to Telecommunications Relay Service for people who are deaf or hard of hearing. So 8-1-1 is the one tied to utility location and safety in business operations.
