How DLT registration works
TRAI DLT registration is mandatory for all bulk SMS in India. We run the entire process for Mumbai and Maharashtra businesses — you just approve the details.
Business Registration
We register your business on the DLT platform and obtain your Principal Entity ID (PE ID) — the 15-digit identity every sender needs.
Header & Template Approval
We set up your 6-character sender ID (e.g. DUOTCH) and submit your content templates for TRAI approval — including English and Marathi templates for Mumbai audiences. Approval typically takes 1–3 working days.
Go Live
Once templates are approved, you start sending. Transactional OTPs and alerts run 24×7; promotional SMS follow TRAI's 9 AM–9 PM window.
