Techniques for ver ring identity and/or location of a customer. One embodiment involves receiving a customer-provided address from a customer in a communication via a computer network or telephone network. The customer is a person or entity paying to receive calls from a resident of a controlled access residential institution. The embodiment further involves accessing a computer system to identify location information associated with the customer, the location information derived from additional information within or about the communication and determining a reliability estimate of the customer-provided address by comparing the customer-provided address with the location information associated with the customer that was identified based on the additional information. The embodiment may involve notifying a telecommunications provider, the controlled access residential institution, or law enforcement based on the reliability estimate of the customer-provided address.
