Abstract
A method and an apparatus are disclosed to enable a public switching network to limit the geographical calling area of calls charged to a credit card. When a credit card call is originated, the called party number is included as part of the credit card validation request. The called party number is compared against numbers stored in a call restriction table previously entered by the owner of the credit card. The network accepts or denies credit card calls as a result of this comparison.
