What does LATA stand for in the context of 9-1-1 routing?

• A. Local Transportation Area
• B. Local Transport Authority
• C. Local Transport Area
• D. Line Transport Area

Answer: (C)

In 9-1-1 routing, you’re dealing with geographic boundaries that determine how a call is carried from the caller to the PSAP. A LATA is the Local Transport Area—the geographic region over which the local carrier’s transport network operates to deliver the call toward the PSAP. This concept helps routing systems know which networks and paths to use for the transport portion of the call, so it reaches the correct answering point. The option Local Transport Area aligns with this routing boundary idea. The other terms describe organizations or nonstandard terms and don’t represent the routing geography used to direct 9-1-1 calls. (Note: in telecom, you’ll also see Local Access and Transport Area as a similar term, but the test choice here uses Local Transport Area.)
