At a minimum, the following is needed: The name, address, telephone number, and signature of the interviewee (i.e., requester). The date of the telephone interview. A copy of the text or script used by the caller. An indication that a “code” word (e.g., mother’s maiden name) was established between the caller and the interviewee. A business reply card or similar record-collection device that obtains the signature of the requester.
