US state LATAs The city or place name given with some LATAs is the name given to identify the LATA, not the limit of its boundary. Generally this is the most significant metropolitan area in the LATA. In some cases, a LATA is named after the largest phone exchange in the LATA that was historically served by an RBOC. For example, the largest city in the Pahrump LATA in Nevada is
Las Vegas. Since Las Vegas was not historically served by an RBOC, the LATA is named after the smaller town of Pahrump, which was historically served by Nevada Bell (now AT&T Inc.). Also, listing under a state does not necessarily limit the LATA's territory to that state; there may be overlaps as well as
enclaves. Areas that include notable portions of other states are explained, but not all LATA state overlaps may be detailed. LATA boundaries are not always solidly defined. Inter-carrier agreements, change proposals to the
Federal Communications Commission (FCC), and new wiring developments into rural areas can and do often alter the effective borders between LATAs. Many sources on LATA boundary information conflict with each other at detailed levels.
