This list shows which carrier handles calls placed to 800-XXX numbers. Choice of carrier routing on calls to 800-xxx numbers cannot be overridden with 10xxx routing. It should also be noted that on calls to 800 numbers, the called party either immediatly in some instances or on a delayed basis receives a record of numbers which called. This identification of the calling party cannot be overridden with *67 or the "line-blocking" associated with Caller-ID. 202 RCCP RADIO COMMON CARRIER PAGING 212 RCCP RADIO COMMON CARRIER PAGING 213
