Can I still receive a WhatsApp OTP on my non-toll-free service number?

Can I still receive a WhatsApp OTP on my non-toll-free service number?

⚡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:

  1. Send a formal email (template below).
  2. Attach proof of business criticality.
  3. Include a liability statement accepting full risk.



4. What happens if the client insists 

We will:

  1. Explain all risks in writing.
  2. Collect written confirmation (liability statement).
  3. 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
