Abstract

When a telephone caller charges a call to a commercial credit card an announcement which includes the name of the credit card issuer is supplied to the caller after the validation of the credit card. In a preferred embodiment, the issuer of the commercial credit card is identified, for purposes of announcing its name, by examining the prefix code of a credit card number supplied by the calling party. Also, in the preferred embodiment, not only the issuer of the commercial credit card but also the name of the telephone carder is supplied as part of the announcement given prior to connecting the calling station to the called station after validation of the credit card. An illustrative such announcement is "Thank you for using AT&T and for charging this call to your American Express card".
