    Abstract: A method and device for providing prepaid 800 and/or 900-type caller services. A caller provides a call request to a telecommunications service provider that can include an 800 or 900 telephone number and an account number for a prepaid account associated with the 800 or 900 telephone number. A determination is made if the prepaid account is authorized for the desired 800 or 900-type call, and if the account is authorized, the caller is connected to the called party associated with the 800 or 900 telephone number. When the call is completed, charges associated with the call are determined and charged to the prepaid account or other party, as desired. The prepaid account is then adjusted to reflect the determined charges.
