TRAI compliance

Three numbers that matter before you send an SMS in India.

DLT is not optional. Skipping it means filtered messages, suspended headers, and operator-level penalties.

Per-violation penalty
₹50K – ₹5L

TRAI fines for non-DLT or unregistered template SMS, on top of operator suspensions.

Mandatory since 2021
100%

All bulk and transactional SMS to Indian numbers must travel through DLT-registered chains.

End-to-end onboarding
5–10 days

From KYC to first compliant send for a small business with documents ready.

The DLT pipeline

Five gates between you and a compliant first SMS.

Most teams confuse header with sender ID, or skip consent templates. We don't — and we don't let your DLT account either.

01

Entity registration

Business KYC submitted on operator-run DLT portals (Vilpower / Smartping / etc.).

Configurable
02

Header (Sender ID)

Approve 6-character sender headers per category — Transactional / Service / Promotional.

Configurable
03

Consent template

Map a consent template to your sender header so opt-ins are auditable.

Most failures here
04

Content template

Each message body registered with placeholders, mapped 1:1 to your API payloads.

Final mile
05

API integration

Provider keys, retries, DLR webhooks, and a sample send wired into your backend.

Where it goes

Operators we register on, every time.

Once approved, the same header propagates across operators in 24–72 hours.

Template anatomy

A registered content template — and why every part matters.

Common questions

DLT, briefly demystified.

Do I need DLT if I send only OTPs?

Yes. All operator-bound SMS to Indian numbers — including OTPs — flow through DLT-registered headers and templates since the 2021 TRAI mandate.

Can the same header send to all operators?

Yes — once registered on one operator DLT portal, the header is replicated across operators in 24–72 hours. We track the rollout.

How long do template approvals take?

Header: usually 2–4 hours. Content templates: 2–12 hours depending on operator queues and content category.

Do you handle promotional templates too?

Yes. Promotional needs DND scrubbing, time-window enforcement, and stricter content review — we configure all of it.
