Abstract: This invention relates to arrangements for providing pre-authenticated access from a caller to a service provider. The caller dials the number of the service provider and subsequently enters a personal identification number (PIN) or other suitable authentication data, and, if necessary, an account number. A data base in the communications carrier verifies that the caller has been authorized to access the service provider and that the PIN is correct for that caller and forwards the call to the service provider only if both checks are satisfied. Only preauthenticated calls are delivered to the service provider, and the caller need only remember one PIN for all the service providers accessed by this arrangement.
