How OTP, transactional, and promotional SMS routes apply specifically to lending, payments, and banking — and why getting the classification right matters more for fintech than any other industry.
Fintech companies in India must register as a Principal Entity on TRAI's DLT platform and get sender IDs and message templates approved before sending any bulk SMS — OTP, transactional, or promotional. Each route serves a different purpose: OTP for auto-expiring verification codes, transactional for account-related content like payment alerts, and promotional for marketing content like loan offers. MetaReach handles the full registration process at no extra cost. Part of our fintech communication solutions.
Every fintech SMS falls into one of three TRAI-regulated categories, and using the wrong one is the single most common compliance mistake in the industry. A login OTP misclassified as promotional could be blocked by DND filtering at the exact moment a customer is trying to complete a transaction. A loan offer sent on a transactional route to dodge DND restrictions risks the entire sender ID being flagged — taking down payment alerts and OTPs along with it.
Each route has a distinct purpose, a distinct set of rules, and a distinct consequence for getting it wrong.
Auto-expiring verification codes for login, transaction approval, and account security. Delivered on the fastest available priority connection, 24/7, regardless of DND status. See our OTP authentication for fintech apps deep dive for sub-6-second delivery details.
Account-related, non-promotional content: payment confirmations, balance updates, fraud alerts, EMI deduction notices. Also DND-exempt, because customers expect and depend on this content regardless of DND status.
Marketing content: loan offers, credit card promotions, new product announcements. Respects DND filtering and can only be sent between 9 AM and 9 PM under TRAI regulations.
Misusing a route has real consequences. Sending promotional content on a transactional route to dodge DND restrictions violates TRAI rules and risks template rejection, sender ID suspension, or blacklisting — which can take down OTPs and payment alerts running on the same sender ID.
Register your fintech entity as a Principal Entity on the DLT platform, get a sender ID approved under that entity, and submit exact message content for template pre-approval for each of the three routes you'll use.
MetaReach's DLT registration support team manages this entire process end-to-end, including resubmission if a first draft is rejected.
Yes. OTP, transactional, and promotional SMS all require a registered Principal Entity, approved sender ID, and pre-approved message templates on the DLT platform.
OTP is for auto-expiring verification codes, transactional is for account-related content like payment confirmations, and promotional is for marketing content like loan offers. Only OTP and transactional bypass DND restrictions.
This misuses the route's approved purpose under TRAI rules and risks template rejection, sender ID suspension, or blacklisting of the sender.
Principal Entity registration typically takes a few working days, with template approval ranging from same-day to a few days depending on complexity.
