Complete Guide to DLT Registration, Bulk SMS, OTP & SMS API Services in India (2026)

If you are planning to use bulk SMS, OTP services, or SMS API for your business in India, then understanding DLT registration and TRAI compliance is extremely important. Without proper DLT registration, SMS delivery can fail, sender IDs can get blocked, and campaigns may stop completely.

📌 Understanding DLT Registration in India

DLT (Distributed Ledger Technology) was introduced by TRAI to stop spam and fraudulent SMS communication. Every business must register as an entity, approve sender IDs, and submit message templates before sending SMS.
