Why choose Guru SMS in Guwahati?
Integration takes minutes — REST API, sample code in every major language, and engineers who actually answer when your Assam team has a question at midnight. OTP is critical infrastructure, and we support it like critical infrastructure.
Guwahati is the northeast's gateway, with tea auctions and distribution networks spanning seven states.
OTP SMS for Guwahati businesses
From tea trade, oil and gas, logistics, retail platforms to local delivery apps, Guwahati businesses use our OTPs for signup verification, payment confirmation, COD validation and password recovery. Every verified number cuts fraud, cleans data and protects revenue — at a cost of paise per code.
Our coverage in and around Guwahati
As one of India's major commercial centres, Guwahati demands messaging infrastructure that performs at metro scale — high parallel throughput, instant delivery reporting and routes that hold up during peak campaign hours. Our Assam network does not stop at the city limits either — the same OTP SMS routes, DLT assistance and account support cover Goalpara, Jorhat and Karimganj, so multi-branch businesses can run every location from a single Guru SMS account.

How long does OTP API integration take for a Guwahati business?
About 15 minutes to first test code using our REST API and sample scripts; a production integration with delivery webhooks is usually same-day work. Our engineers assist your Guwahati team directly during integration at no extra cost.
Is DLT registration needed for OTP messages in Guwahati?
Yes — OTP templates must be registered on DLT like all commercial SMS in India. The process is straightforward for transactional templates and we complete it with you free of charge; most Guwahati businesses are approved within days.
Can OTP SMS work alongside my promotional campaigns?
Yes, on one account — but on separate routes. OTPs ride the dedicated transactional lane while promotions use marketing routes, so a big Guwahati campaign never delays a login code. Reporting stays unified in one dashboard.
What does OTP SMS cost in Guwahati?
Per-message transactional rates with volume slabs — no setup fee, no rental, free sandbox. OTP volumes grow fast, so slabs matter: share your monthly code estimate and we will quote exact Guwahati pricing immediately.
Do OTPs deliver on DND numbers in Guwahati?
Yes. OTPs are transactional messages, which TRAI permits to DND-registered numbers. Your Guwahati users receive verification codes regardless of their DND status — one reason the transactional route and proper DLT templates matter.
Can I monitor my OTP delivery performance?
In real time. The dashboard shows sent, delivered, failed and average delivery time, sliceable by hour and operator — so your Guwahati team can verify our 98-99% transactional delivery claim against your own traffic, every day.
