Overview#Interexchange Carrier (IXC) is a United States legal and regulatory term for a telecommunication company, commonly called a long-distance telephone company.
Interexchange Carrier is defined as any carrier that provides services across multiple Local Access and Transport Areas (intraLATA). Calls made on telephone circuits within the local geographic area covered by one local network are handled only by that intraLATA carrier, commonly called a Local Exchange carrier. IntraLATA usually refers to rated or toll calls between LATA within state boundaries, as opposed to interstate, or calls between LATAs in different states.
Local calls are usually defined by connections made without additional charge whether the connected call is in the same LATA or connects to another LATA with no charge.
