  • Payment reminders and transaction notifications
  • Account statements and balance updates
  • Service alerts and system notifications related to subscribed services

Regulatory certificateBusiness category certificate issued by applicable regulatory body (RBI, SEBI, IRDAI, or PFRDA)
DLT registrationPrincipal Entity registered on Tata DLT portal (Plivo has partnered with Tata; entities on other DLT platforms are not supported)

Provisioning Process

All processes outlined below must be completed by the BFSI entity.

Step 1: DLT Portal Registration

Register as a Principal Entity (PE) on the Tata Teleservices DLT portal. This establishes your organization as the authorized entity responsible for all voice communications through allocated 160-series numbers. After successful registration and approval, a Principal Entity Certificate is issued to your registered email address.
Refer to the Tata DLT Process Guide for detailed registration instructions.

Step 2: Number Allocation

Required Documentation

Submit the following documents to Plivo:
  • Principal Entity Certificate (issued by Tata Teleservices)
  • Approved India Compliance Application Alias
  • Voice Header Registration Declaration (filled and signed)

Plivo’s Allocation Process

Upon receipt of these documents, Plivo will:
  1. Reserve 160-series numbers to your account
  2. Provide Plivo’s Telemarketer ID (TM ID)
  3. Issue a No Objection Certificate (NOC) letter linking the allocated numbers to your PE ID

Step 3: Voice Header Registration

Register the Voice Header on the Tata DLT portal using the allocated 160-series number under your Principal Entity ID. During registration, select Plivo’s Telemarketer ID as provided in Step 2.

Required Documents for Upload

  • Business category certificate from regulatory body (RBI, SEBI, IRDAI, or PFRDA)
  • No Objection Certificate (NOC) letter issued by Plivo

Step 4: URN Submission to Plivo

After submitting the Voice Header registration, provide the following to Plivo:
Required ItemDescription
URNUnique Registration Number (also called Submission ID)
ScreenshotCompleted submission from DLT portal

Plivo Review and Approval

Plivo reviews the header registration for completeness and accuracy, then coordinates with Tata by sharing the URN and allocated 160-series number for final regulatory approval.

Step 5: Content Template Registration

After Plivo confirms that the voice header has been approved by Tata Teleservices, register the Voice Content Template on the DLT portal. These templates define the specific messages transmitted using the 160-series number. Once template registration is complete, the 160-series number is ready for live operations.

FAQs

Can I use 160-series numbers for promotional calls?

No. 160-series numbers are strictly for transactional and service-related communications only. Using them for promotional or marketing purposes violates TRAI regulations and may result in number disconnection and penalties.

What if my entity is registered on a DLT platform other than Tata?

Plivo has partnered exclusively with Tata for 160-series provisioning. Entities registered on other DLT platforms (such as Airtel, Vi, or BSNL) are not supported. You need to register as a Principal Entity on the Tata DLT portal.

What happens if my Voice Header registration is rejected?

You receive notification via the DLT portal with the reason for rejection. Common reasons include:
  • Incomplete or incorrect documentation
  • Mismatch between PE details and submitted documents
  • Invalid NOC or regulatory certificate
Review the rejection reason, correct the issue, and resubmit the registration.

Do I need to renew my 160-series numbers?

Yes. Maintain active registration on the Tata DLT portal and ensure all compliance documents remain current. Check with Tata regarding renewal timelines for Principal Entity registration and content templates.
