What happened

Telecom Regulatory Authority of India (TRAI) · TRAI tightened India’s anti-spam rules, lowering complaint thresholds and regulating A2P calls. The changes

Key facts

  • 3 unique consumer complaints within 10 days
  • 5 reported incidents trigger further investigation
  • up to 5 paise per minute A2P termination charge
  • 15 days to file complaint appeals
  • 7-day limit on commercial communication after a customer inquiry
  • 6 hours to suspend misused headers or templates
  • 1 year disconnection and blacklisting for responsible telemarketers

Why this matters

In diligence, test targets’ A2P call exposure, declared-number compliance, consent architecture, complaint rates and third-party telemarketer contracts, as regulatory lapses could impair growth and create integration liabilities.

What to watch

  • TRAI enforcement notices, suspension volumes and complaint-threshold interpretations affecting A2P calling.
  • Whether major telecom operators introduce stricter registration, caller-ID authentication or per-call compliance checks.
  • Increase in customer complaints about missed delivery, return, OTP, loan-verification or support calls.
  • Rising cost or lead-time for declared-number provisioning and telemarketer onboarding.
  • Marketplace mandates requiring sellers, logistics partners and service vendors to use approved communication stacks.
  • Conversion-rate changes for phone-originated leads relative to WhatsApp, SMS, app and email campaigns.
  • Audit all customer-facing phone numbers, sender identities, telemarketer registrations and third-party calling vendors.
  • Separate transactional, service, delivery and promotional call journeys; define the evidence required to classify each interaction.
  • Build consent capture and withdrawal records at customer, channel, purpose and timestamp level.
  • Set automated controls to stop commercial follow-ups after the seven-day inquiry window unless fresh consent is captured.
  • Move high-volume outreach toward opt-in WhatsApp, app push, email and authenticated SMS while preserving fallback service paths.
  • Create real-time complaint, delivery-failure and number-suspension dashboards with escalation ownership.
  • Update vendor contracts to include TRAI compliance SLAs, audit rights, indemnities and rapid number-replacement procedures.
