⚡Quick answer
• No. SMS-based OTP support for all app registrations (WhatsApp, e-commerce, social media, etc.) has been discontinued for every existing service number.
• Exception: Only business-critical cases may be considered after formal review and a signed liability statement.
1. Why OTP service was discontinued
Government regulations and new risk-control measures classify OTP activity as high-risk because of:
• Increased monitoring by the Digital Intelligence Unit (DIU)
• High incidence of telecom fraud involving OTPs
• Frequent SIM, device, or location changes that trigger automatic red flags
Continuing OTP usage can lead to:
• Immediate number suspension
• Permanent service disconnection
2. About the DIU & fraud-risk triggers
The Digital Intelligence Unit (DIU), under the Department of Telecommunications (DoT), prevents telecom fraud through:
• AI-based SIM & identity analysis (e.g., ASTR)
• Fraud-detection tools & pattern monitoring
• Consumer-facing portals such as Chakshu and Sanchar Saathi
Impact on your number:
• OTP requests, SIM swaps, or rapid location changes can trigger pre-emptive suspension, even if no misuse occurs.
3. Requesting an OTP in business-critical cases
By default, OTP requests are rejected. For business-critical scenarios only:
- Send a formal email (template below).
- Attach proof of business criticality.
- Include a liability statement accepting full risk.
4. What happens if the client insists
We will:
- Explain all risks in writing.
- Collect written confirmation (liability statement).
- Proceed only after internal approval.
Note:
• Suspension risk remains extremely high.
• Recovery or reinstatement is not guaranteed.
5. Safer alternatives to OTP registration
• Use dedicated, compliant numbers for each app registration.
• Avoid shared or frequently migrated numbers.
• Plan registrations in alignment with telecom regulations.

6. Updated TAT for server/location change
Request Type | New TAT | Reason |
Server or location change | 24 hours (1 business day) | Frequent or rapid location switching is flagged as suspicious and heightens suspension risk |
7. New 2026 compliance triggers
• SIM Binding Rule: Changing a SIM with the same IMEI now raises alerts.
• Suspicious-activity detection:
– OTP usage
– UCC (Unsolicited Commercial Communication)
– Frequent device/location changes
These events are monitored via DoT systems.
8. Expected outcome of following this policy
By complying, you ensure:
• ✅ Reduced risk of number suspension
• ✅ Improved service stability
• ✅ Full compliance with government regulations
Important note for clients: These rules safeguard
• Your number from permanent suspension
• Your business continuity
• Adherence to evolving telecom regulations
