A toll charge and rate inquiry service for portable numbers allows a telephone system user to access billing and toll telephone charge information prior to establishing a telephone call connection between the telephone system user and a called party. The telephone toll charge information is extracted from a portable telephone number logical matrix. A telephone system user using the toll charge and rate inquiry service for portable numbers can use the telephone toll charge information to determine prior to establishing a telephone call connection whether to complete the telephone call to the called party with a toll charge. Upon request, the user is automatically connected to the called party.
