What DLT registration does a bank or NBFC need?
Registration under the Banking / Financial Services category on Jio TrueConnect (or any DLT operator platform). Principal Entity registration with your CIN and RBI licence details. Header approval, typically 6 characters, with your recognised short-code (like HDFCBK, ICICIB). Every message template registered separately: OTP, transaction alert, EMI reminder, cheque bounce notice, KYC pending, statement generated, and so on. Categories matter: OTP goes as Service Implicit, EMI reminder as Service Explicit with consent, promotions as Promotional. Get the category wrong and delivery drops.
How do you hit sub-3-second OTP delivery for banking apps?
Three engineering choices. First, dual-vendor active-active routing (not failover) so both SMS providers send simultaneously and we accept whichever the operator returns first. Second, direct enterprise API connections (not aggregator resellers) with two of Kaleyra, MSG91, Karix, Tanla so the operator ingress is one hop. Third, real-time TPS monitoring with auto-throttle when a vendor slows down. For login OTP we hold P95 delivery under 4 seconds across every operator including BSNL. Voice OTP is available as fallback for pincodes with weak SMS delivery.
Can BFSI use WhatsApp Business API?
Yes, with restrictions. Meta permits banks, NBFCs and insurers on WhatsApp Business API for transactional and utility conversations (statement, EMI reminder, policy renewal, claim status). Marketing templates for financial products need extra Meta approval and are often rejected for anything resembling loan solicitation. WhatsApp is not permitted for OTP as a primary channel by RBI norms for banking auth, though it is fine as a supplementary notification of the same transaction. We handle Meta BSP onboarding, template approval, and BFSI-specific content moderation before submission.
What RBI rules apply to messaging customers?
Several. RBI mandates immediate transaction alerts to registered mobile numbers for any debit or credit above the threshold notification limit. Payment fraud circulars require alert-and-hold flows for suspicious transactions. Fair Practices Code (for NBFCs and lending) restricts collection communication to specific hours and prohibits harassment, so overdue EMI SMS scheduling must respect 8 AM to 7 PM windows. RBI KYC guidelines require notification when KYC lapses. We build all these guardrails into the message scheduling layer so ops teams cannot accidentally violate.
How do IRDAI consent rules affect insurance messaging?
IRDAI requires explicit consent for any solicitation-related communication (renewal offers, new product cross-sell, top-up recommendations). Servicing communication (premium due, policy issued, claim update) does not need explicit consent because it flows from the policyholder relationship. Opt-out for solicitation must be honoured within 24 hours and logged. Our BFSI compliance package includes IRDAI-aligned consent capture, purpose-tagged messaging, and audit-ready opt-out records that insurance ombudsman investigations can access.
How do collections messaging comply with RBI Fair Practices?
RBI Fair Practices Code and the 2022 Digital Lending Guidelines are strict. Contact windows limited to 8 AM to 7 PM local time. No use of threats, intimidation, or public disclosure of the debt. Maximum contact frequency capped per week. Language must be respectful and identify the lender by registered name. We wire the collections message scheduler to enforce all four automatically: no send outside window, template pre-approved for tone, contact frequency counter per borrower, per-lender identity block in every template. Non-compliance reports flag to your compliance officer weekly.
What happens if a DLT header is suspended mid-day?
It happens more than banks admit. A template rejection, a spam complaint spike, or a routine audit can freeze a header. Our architecture always has a secondary registered header ready and warmed. If the primary suspends, traffic switches to the secondary within 2 minutes and ops gets a PagerDuty alert to file the reinstatement request. Meanwhile, WhatsApp continues on the parallel channel for transactional messages that support both. We have handled 12+ header suspension events for BFSI clients across the last 18 months without a single OTP outage.
