Two routes

Two ways to send SMS OTP to Indian numbers

EazyOTP offers two SMS routes for India. Both use the same API style, so you can start on one and switch to the other later.

Global SMS route compared with DLT SMS route for India
  Global SMS route DLT SMS route (domestic)
When you can start As soon as the service is activated After DLT registration and template approval
Your DLT registration Not required: no DLT template or sender ID approval Required: entity, sender ID (header) and OTP template
Sender ID Set by the international route Your approved brand header
Pricing International SMS rate for India Domestic DLT SMS rate
API endpoint globalsmseazyotp smseazyotp
Best for New launches, MVPs, pilots and fast go-lives Steady, high-volume domestic traffic

Compliance note: DLT is how TRAI regulates domestic business SMS in India, and EazyOTP does not bypass it. The Global SMS route is international SMS traffic, so it is outside domestic DLT templates, and its sender ID and pricing differ. For your own brand sender ID on domestic routes, complete DLT registration and use the DLT SMS route.

Instant SMS OTP India: start on the Global SMS route today and switch to the DLT SMS route when approved
Developer API

Send your first OTP to an Indian number

Use the Global SMS endpoint with the number in international format (91 followed by the 10-digit mobile number). When your DLT approval comes through, change globalsmseazyotp to smseazyotp. The rest of your integration stays the same.

Call the API only from your server, because the API key is part of the URL.

FAQ

Instant SMS OTP questions

Can’t find your answer? Contact our team or read the EazyOTP API documentation.

Can I send OTP SMS in India without my own DLT registration?

Yes, on the EazyOTP Global SMS route, which does not need DLT template or sender ID approval from you. The domestic DLT SMS route always needs DLT registration and approved templates. Many businesses start on the Global route and move to DLT later.

Is the Global SMS route allowed for Indian numbers?

Yes. Messages on the Global SMS route reach Indian numbers as international SMS traffic. The sender ID and per-message rate can differ from the domestic DLT route, so check OTP pricing or ask our team for current India rates.

How fast can I start?

Once the Global SMS Eazy OTP service is active on your account, you can test in the sandbox and then send live OTPs straight away. No DLT approval wait applies.

When should I switch to the DLT route?

Switch once your traffic is steady and you want your own brand sender ID and domestic routing. Register on a DLT platform, get your OTP template approved, then change the endpoint from globalsmseazyotp to smseazyotp.

What is DLT and why does it exist?

DLT (Distributed Ledger Technology) is TRAI’s system for registering business senders, headers and SMS templates in India. It exists to cut spam and fraud, so domestic business SMS must use registered sender IDs and approved templates.

Is there an option that avoids SMS templates altogether?

Yes. WhatsApp OTP uses Meta-approved authentication templates instead of DLT SMS templates. See the WhatsApp OTP API for India.
