Which number is used by local exchange carriers for business office use?

• A. 911
• B. 811
• C. 411
• D. 711

Answer: (B)

The number designated for call-before-you-dig is the one used by local exchange carriers for coordinating with utility locate services. When planning excavation or digging, calling this number connects you to the utility locate centers so underground cables and pipes can be marked before work begins. This safety-focused function is why it’s specifically associated with business operations that involve digging or construction, making it the best fit for the question. Emergency services use another number, directory assistance is a different service, and the relay service for hearing or speech impaired is yet another, so those options don’t apply to coordinating underground utility locates.
