Answer:
The user of a consumer report containing an extended Fraud Alert must contact the consumer in person or by using a telephone number or other reasonable contact method designated by the consumer. [605A(h)(2)]
You must also respond to ID Theft Ref Flags (a fraud alert is one of them). [334.90] Contacting the customer and denying the application are two acceptable responses. Refer to Appendix J for more information on acceptable responses.
