The FCC's Truth-in-Billing  rules require telephone companies to provide clear, non-misleading, plain language in describing services for which customers are being billed. The company sending the bill must identify the service provider associated with each charge. If a bill contains charges in addition to basic local service, it must distinguish between charges for which non-payment will result in disconnection of basic local service, and charges for which non-payment will not result in disconnection. Telephone companies must also display, on each bill, one or more toll-free numbers that you can call to ask about or dispute any charge on the bill.
