1. A device, comprising:
a processor; and
a memory that stores executable instructions that, when executed by the processor, facilitate performance of operations, comprising:
determining, according to a consistency criterion, whether a second geographic area associated with an area code of a caller identification number of a call from a communication device is inconsistent with a first geographic area, determined using an indicator associated with the call, associated with a service network from which the call originated; and
in response to determining that the second geographic area is inconsistent with the first geographic area, sending a message to network equipment associated with the service network, wherein the message comprises a request to determine whether the caller identification number is registered for use of a service associated with a provider entity enabled via the service network.
