The Carrier Recovery Fee is a charge associated with the payment of government-imposed fees and to recover the costs of compliance with government-imposed regulatory requirements. It is a not tax or charge required by the government but was implemented to allow telecommunication providers the ability to recover costs for national regulatory fees and programs, connection charges, and account fees.
The Anti-Spam Recovery Fee is a charge associated with the FCC's mandatory STIR/SHAKEN framework. The FCC requires that all providers certify in the Robocall Mitigation Database and that they have fully implemented STIR/SHAKEN to ensure that they are not originating illegal robocalls. The cost for this additional overhead is passed through to the customers.
