DLT Compliant CPaaS Platform for SMS & Voice in India
Any business sending commercial SMS or voice OBD calls in India has to register on TRAI's DLT (Distributed Ledger Technology) platform first - the entity sending the message, the header (sender ID) it sends from, and every message template it uses all need approval before a single message goes out. Skip a step, and even a perfectly written message gets silently dropped by the telecom operator before it reaches anyone.
We've written a full walkthrough of that process in our DLT registration guide, covering Principal Entity, Header and Content Template registration in detail. What follows here is specifically how that process works when you register through Teleopedia rather than navigating the DLT portal directly.
How You Get DLT-Compliant On Teleopedia
- 1
Share your entity details
Provide your business PAN, GST and entity details so we can register you as a Principal Entity on the DLT platform.
- 2
Header (sender ID) registration
We register your Header - the short alphanumeric code recipients see as the sender - against your entity.
- 3
Template registration
We submit every message format you plan to send for Content Template approval, with exact variable placeholders matched to what your system will actually send.
- 4
Mapping to your account
Once headers and templates are approved, they're mapped directly to your Teleopedia account - there's no separate DLT portal for you to manage day to day.
- 5
Go live
Send SMS and Voice/OBD campaigns knowing every template is pre-approved, so nothing gets silently blocked by a telecom operator mid-campaign.
Common DLT Mistakes That Get Messages Blocked
Most DLT delivery failures aren't caused by fraud filters - they're caused by a mismatch between what was registered and what was actually sent. The ones we see most often:
A template variable sends a longer value than what was registered - for example, a promo code longer than the placeholder's approved character range.
Extra punctuation, an emoji, or a line break added to a template after approval, without re-registering the change.
Sending a promotional message on a transactional-only header, which telecom operators filter regardless of content.
Sending promotional SMS outside TRAI's permitted hours, which gets blocked at the operator level even with an approved template.
Our team checks templates against these patterns during setup, and flags a mismatch before it turns into a live delivery failure mid-campaign.

DLT Compliance Questions
What is DLT registration?
DLT (Distributed Ledger Technology) registration is TRAI's mandatory framework requiring every entity and message template sending commercial SMS or voice OBD calls in India to be registered before sending - unregistered messages get silently blocked by telecom operators.
Do I need to register on the DLT platform myself?
No. Once you share your business PAN, GST and template content, our team handles entity, header and template registration on your behalf.
How long does DLT registration take?
Entity registration is typically quick once documents are verified. Template approval timelines depend on the telecom operator's own DLT portal, but our team manages the submission so there's no back-and-forth on your side.
Does DLT registration apply to WhatsApp too?
No, DLT registration is specific to SMS and Voice/OBD under TRAI's regulations. WhatsApp templates go through Meta's own approval process instead, which our team also assists with.
What happens if a template doesn't match what's registered?
Even a mismatched space or punctuation mark between the registered template and the actual message sent is enough to get it blocked - our team checks this during setup so it doesn't surface as a live delivery failure.
