A Local Access and Transport Area is the region a call is routed within before it becomes long-haul. The boundaries were drawn when the Bell System was broken up in 1984: a local carrier could carry a call inside its LATA, and a long-distance carrier had to take it across one. The division still shapes how calls are routed and rated today, which is why every prefix block on this site carries a LATA.
