    What you must provide Evidence of recipient consent (Proof of Opt-in)

    If You Receive an Audit Notice

    1. Check the details—Plivo will provide:
      • Caller Number (your Plivo number)
      • Callee Number (the recipient)
      • Timestamp of the call (in IST)
      • Call UUID associated with the call on Plivo's platform
    2. Gather consent evidence—provide proof of opt-in showing the recipient agreed to receive calls from you.
    3. Submit the proof of opt-in—the details must be provided within 5 days.
    4. Remove the callee from your list—prevent future complaints by removing this number from your calling list.

    Warning: Using a different Plivo number to reach out to the same callee number will be considered a violation and can lead to service disruption.

    Consent Evidence Requirements

    Your evidence must clearly show the recipient agreed to receive calls from you.

    Required elements:

    • Company logo or name
    • Recipient's name
    • Recipient's phone number
    • Date consent was given

    Acceptable formats:

    • CRM screenshot showing the above details
    • Signed consent form
    • Digital opt-in record

    Note: Submit clear, high-quality images with all required elements clearly visible.

    Audit Process

    User complaint Telecom provider Plivo compliance team Customer

    1. A call recipient files a complaint with their telecom provider
    2. The telecom provider identifies Plivo as the originating service
    3. Plivo's compliance team identifies the responsible customer
    4. Customer provides consent evidence within 5 days
    5. Plivo's compliance team reviews and submits to the telecom provider
    6. Customer is notified when the audit is closed

    Consequences

    If you provide valid evidence within 5 days

    • Plivo reviews your submission
    • If additional details are needed, Plivo will contact you
    • Once the telecom provider closes the audit, you'll be notified

    If you submit insufficient evidence

    • Plivo will contact you to request additional or corrected documentation
    • You must respond promptly to avoid escalation within the initial 5 day window from the date of receiving the complaint
    • Failure to provide valid proof of opt-in for any complaint may lead to your account being temporarily suspended or permanently blocked.

    If you fail to respond within 5 days

    • If you fail to respond within 5 days, your account may be temporarily suspended or permanently blocked.
    • Multiple complaints may result in the business being blacklisted by TRAI.
    • For resellers, if compliance details are not correctly mapped to end businesses, the reseller will be required to provide valid proof of opt-in, and Plivo may take action on the entire account. ()

    Note: In accordance with Plivo’s Acceptable Use Policy, Plivo reserves the right to unrent numbers, block traffic, or disable services entirely, depending on the severity.

    Best Practices to Avoid Audits

    • Only call users who have explicitly opted in
    • Honor rejections - If a user doesn't answer or declines, don't call repeatedly
    • Refresh consent every 6 months - As per TRAI guidelines, any consent older than 6 months is not considered valid.
