How Should Your Organization Use This Voice Fraud Policy Template?
This policy template is designed to be adopted by any organization with payment authorization workflows. Replace all bracketed fields with your organization's specific details. Have it reviewed by legal counsel before formal adoption. The policy should be signed by the CFO or executive director and distributed to all staff who handle payments, banking, or vendor relationships.
Voice fraud — including AI-generated voice clone attacks, vishing (voice phishing), and telephone-based social engineering — has become the fastest-growing financial crime vector targeting organizations of every size. The FBI IC3 documented $2.77 billion in Business Email Compromise losses in 2024, and voice-initiated fraud is now frequently layered on top of email-based attacks to add a layer of false urgency and authenticity. Organizations without a documented phone verification policy are operationally exposed: when staff receive a call that sounds like the CFO, a known vendor, or a long-standing client, there is no procedural answer to the question "how do I verify this?"
This template codifies four core controls — callback verification, verbal passphrase authentication, written authorization requirements, and staff training — into a single adoptable policy document. Customization typically takes 30 minutes. All fields requiring organization-specific input are highlighted in teal brackets throughout the document. Once adopted, pair this policy with the companion Voice Clone Attack Incident Response Checklist so your team knows exactly what to do if a fraud event occurs despite these controls. Legal counsel review is strongly recommended before formal adoption.
Section 1: Purpose
This policy establishes procedures to protect [ORGANIZATION NAME] from voice-based fraud, including AI-generated voice clone attacks, vishing (voice phishing), and social engineering conducted via telephone. Voice fraud is the use of a phone call — whether by a human or an AI-generated synthetic voice — to impersonate a trusted individual and induce an employee to take a fraudulent financial action.
The purpose of this policy is to ensure that no employee acting alone, under telephone-based pressure, or without out-of-band verification is able to authorize or process a payment, banking change, or other financial action solely on the basis of an inbound phone call.
Section 2: Scope
This policy applies to all employees, contractors, and agents of [ORGANIZATION NAME] who have authority to:
- Authorize or process wire transfers, ACH payments, or checks;
- Modify vendor or employee banking information;
- Release confidential financial or client information by phone; or
- Approve payroll changes.
This policy applies regardless of the dollar amount of the transaction unless a specific threshold is stated. Compliance is mandatory. Violations are subject to the enforcement provisions of Section 10.
Section 3: Payment Authorization Callback Policy
3.1 No wire transfer, ACH payment, or vendor payment above $[THRESHOLD — SUGGESTED: $2,500] shall be authorized based solely on an inbound telephone call, regardless of whether the caller's identity appears to have been verified by voice recognition or caller ID.
3.2 Before processing any payment change or new wire transfer received by phone, the receiving employee shall:
- Decline to take action during the call;
- Call back the requestor at a phone number on file (not a number provided in the call or its associated voicemail); and
- Verbally confirm the full payment details — payee name, account number, routing number, dollar amount, and purpose — before processing.
3.3 The callback number must come from [ORGANIZATION NAME]'s verified vendor or employee records system, not from caller ID or any number provided during the inbound call.
3.4 If the requestor is unavailable at the verified number, the transaction shall not be processed until the callback is completed. No exception shall be made based on urgency communicated during the original inbound call.
Section 4: Verbal Passphrase Protocol
4.1 [ORGANIZATION NAME] shall maintain a confidential verbal passphrase for use in payment authorization calls. The current passphrase is known only to [LIST AUTHORIZED ROLES — e.g., "the CFO, Controller, and designated backup"].
4.2 Any inbound call requesting a wire transfer, payment change, or banking modification must provide the current passphrase before the employee takes any action. Inability or refusal to provide the passphrase is grounds to immediately terminate the call and report it per Section 7.
4.3 The passphrase shall be changed [FREQUENCY — suggested: quarterly] and whenever an employee with passphrase access leaves the organization. Passphrase rotation shall be communicated in person or via a secure, pre-established written channel.
4.4 The passphrase shall never be communicated by email, text message, voicemail, or any other electronic channel that could be intercepted or observed.
4.5 The passphrase requirement does not replace the callback requirement in Section 3. Both controls apply independently. A caller who provides the correct passphrase on an inbound call has still not authorized a transaction; the employee must still call back on a verified number before taking action.
Section 5: Vendor Banking Change Procedure
5.1 Requests to change a vendor's banking information — including account number, routing number, payment method, or payment contact — shall not be processed based on a phone call or email alone, regardless of the apparent source.
5.2 All vendor banking changes require:
- A written request on vendor letterhead or from the vendor's verified email address (as maintained in [ORGANIZATION NAME]'s vendor records, not as provided in the change request);
- A callback to the vendor at the phone number maintained in [ORGANIZATION NAME]'s vendor records — not a number provided in the written request — to verbally confirm the change; and
- Dual authorization: approval from [ROLE — e.g., "CFO and Controller"] before the change is entered in the accounting system.
5.3 Vendor banking changes shall not be processed within [TIMEFRAME — suggested: 3 business days] of a pending payment to that vendor. If a payment deadline creates pressure to bypass this waiting period, the payment deadline shall be extended rather than the verification requirement waived.
5.4 A log of all vendor banking changes shall be maintained by [ROLE — e.g., Controller / AP Manager], including the date of the request, the verification steps completed, and the names of the dual authorizers.
Section 6: Employee Direct Deposit Change Procedure
6.1 Changes to employee direct deposit banking information shall not be processed based on a phone or email request alone, regardless of the apparent source.
6.2 Direct deposit changes require in-person or authenticated payroll portal submission by the employee, plus verification of employee identity at the time of submission.
6.3 If a phone or email request is received to change direct deposit information, the HR or payroll processor shall:
- Decline to process the change from the inbound request;
- Contact the employee directly at their known, on-file contact number to confirm they initiated the request; and
- Require in-person or authenticated portal-based resubmission before the change is entered.
6.4 If the employee cannot be reached at their on-file contact number, the direct deposit change shall not be processed until in-person verification is completed.
Section 7: Suspicious Call Reporting
7.1 Any employee who receives a call they believe may be fraudulent, impersonating, or AI-generated shall immediately:
- Decline to take any action requested during the call;
- End the call;
- Report the call to [ROLE — e.g., "IT Security / CFO / HR Director"] within [TIMEFRAME — suggested: 1 business hour]; and
- Preserve any voicemail, caller ID record, or call log associated with the call and provide it to the designated contact upon request.
7.2 [ORGANIZATION NAME] shall maintain a Voice Fraud Incident Log. All suspected voice fraud calls shall be entered in the log regardless of whether a financial loss occurred. The log shall capture at minimum: the date and time of the call, the phone number displayed, a summary of the request made, the name of the employee who received the call, and the disposition.
7.3 Employees shall not be penalized for reporting a suspicious call that is later determined to have been legitimate. A culture of reporting is a core control in this policy. Failure to report a suspicious call, by contrast, is a policy violation.
7.4 If a voice fraud call results in a financial loss or the disclosure of confidential information, [ORGANIZATION NAME] shall immediately contact its bank, file a report at ic3.gov (FBI Internet Crime Complaint Center), and engage legal counsel. The 72-hour window following a fraudulent wire is critical — see the companion Incident Response Checklist.
Section 8: Staff Training Requirements
8.1 All employees in scope (Section 2) shall complete voice fraud awareness training within [TIMEFRAME — suggested: 30 days of policy adoption].
8.2 Training shall be repeated [FREQUENCY — suggested: annually] and shall cover:
- How AI voice cloning works and why caller ID is not a reliable verification method;
- The callback verification and passphrase protocols established in this policy;
- How to identify and report suspicious calls under Section 7;
- Common social engineering pretexts used in voice fraud (urgency, authority, fear of consequences); and
- Review of real-world voice clone fraud scenarios drawn from [SOURCE — suggested: FBI IC3 Annual Report, FTC Consumer Sentinel reports].
8.3 Training completion shall be documented and records kept for [RETENTION — suggested: 3 years]. Completion records shall be available for review by auditors, insurers, and regulators upon request.
8.4 New employees in scope shall complete training within [TIMEFRAME — suggested: 14 days of their start date] and shall not be granted authorization to process payments or banking changes until training is documented as complete.
Section 9: Technology Controls
9.1 [ORGANIZATION NAME] [SHALL / SHOULD CONSIDER — choose one] deploy real-time AI voice authentication tools on its primary business phone lines to detect and flag synthetic or cloned voices on incoming calls before any financial instruction is acted upon.
9.2 The IT department shall maintain a log of all wire transfer authorizations, including the name of the authorizing employee, the verification method used (callback, passphrase, written confirmation), and the dual authorization approvers.
9.3 Caller ID shall not be treated as a verification method under any circumstance. Employees shall be trained that caller ID is trivially spoofable and that matching caller ID is not evidence of the caller's identity.
9.4 [ORGANIZATION NAME] shall review available voice fraud detection technology options annually as part of the policy review cycle described in Section 10.
Section 10: Policy Violation and Enforcement
10.1 Failure to follow this policy may result in disciplinary action up to and including termination, depending on the circumstances and applicable employment law.
10.2 Any employee who processes a payment in violation of this policy and thereby causes a financial loss to [ORGANIZATION NAME] may be subject to personal liability, subject to applicable law and the organization's fidelity bond or commercial crime coverage terms.
10.3 This policy shall be reviewed annually by [ROLE — e.g., CFO / Controller / Compliance Officer] and updated to reflect changes in the threat landscape, staffing, banking relationships, or regulatory requirements.
10.4 Exceptions to this policy require written approval from [ROLE — e.g., CFO] and shall be documented with a business justification and mitigating controls before the exception is granted.
Employee Acknowledgment
"I have read, understood, and agree to comply with the [ORGANIZATION NAME] Voice Fraud Prevention Policy. I understand that failure to comply may result in disciplinary action."
Retain completed acknowledgment forms for [RETENTION PERIOD]. Provide a copy to the employee upon request.
What Should You Do If a Voice Clone Attack Occurs Despite These Controls?
Even with strong prevention controls in place, voice clone attacks can succeed. If your organization experiences a voice clone attack or wire fraud event, the response protocol — including the 72-hour FBI Financial Fraud Kill Chain window — is the difference between recovering funds and absorbing the loss.
When a fraudulent wire clears, time is the determining variable in whether funds are recovered. The FBI Financial Fraud Kill Chain (FFKC) froze $561.6 million in 2024 and has a 66% success rate when activated within 72 hours. The moment you discover a fraudulent payment, you need a clear protocol — not a decision tree built under stress. Our Voice Clone Attack Incident Response Checklist gives your team the exact sequence of calls and filings to execute in the first hours after discovery, including the IC3 submission process, bank recall procedures, and evidence preservation steps.
If you want to understand your organization's exposure before an incident occurs, the Vicall risk assessment takes under five minutes and identifies which workflows have the highest procedural vulnerability to voice-initiated fraud.
Frequently Asked Questions
No federal law explicitly mandates a standalone voice fraud prevention policy by that name. However, contractual and regulatory obligations — including HIPAA, FFIEC guidance for financial institutions, and GLBA safeguards rules — create de facto requirements for organizations to document controls against social engineering and unauthorized payment authorization. Many commercial crime and cyber liability insurers now require documented phone verification procedures as a condition of coverage or premium eligibility. Even without a formal legal mandate, the absence of a documented policy substantially increases an organization's exposure in the event of a fraud loss.
At minimum, a voice fraud prevention policy should be reviewed and reissued annually. Beyond the annual cycle, the policy should be updated any time a material change occurs: a new payment processor or banking relationship is established, a key authorized approver (CFO, controller, HR director) joins or leaves the organization, the verbal passphrase is changed, or a new fraud incident or near-miss reveals a procedural gap. The threat landscape for AI voice cloning is evolving rapidly — the FBI IC3 and FTC publish updated guidance that should be incorporated into training materials at each annual review.
The voice fraud prevention policy should be approved and signed by the CFO or, for non-profit and government organizations, the executive director. Legal review is strongly recommended before formal adoption to ensure the policy's language is consistent with applicable state law, employment law, and the organization's existing contracts. The signed policy should be distributed to all employees in scope — anyone who handles payments, banking relationships, vendor management, or payroll — and retained in the organization's policy document library with signed acknowledgment forms.
A verbal passphrase is a shared secret word or phrase known only to authorized approvers within an organization — for example, the CFO, controller, and a designated backup. When an employee receives a phone call from someone claiming to be an executive or authorized party and requesting a payment or banking change, the employee asks for the current passphrase before taking any action. If the caller cannot provide it, the request is declined. The passphrase is changed quarterly and whenever an employee with passphrase access leaves the organization. It is never communicated by email, text, or voicemail. The passphrase requirement operates alongside — not instead of — the callback verification protocol.
