SMS DLT Template Registry and Compliance

Distributed Ledger Technology (DLT) compliance, US A2P 10DLC registration, Entity IDs, Header approvals, and credit calculation rules.

Regulatory Compliance for Commercial SMS

To combat consumer spam, telecom regulatory bodies worldwide enforce strict pre-registration frameworks before commercial text messages can terminate on subscriber handsets:

• India (TRAI): Mandates blockchain-based Distributed Ledger Technology (DLT) registration (Jio DLT, Airtel DLT, Vodafone Idea Vilpower).
• United States (FCC / CTIA): Mandates Application-to-Person 10-Digit Long Code (A2P 10DLC) brand and campaign vetting via The Campaign Registry (TCR).

BrokerOS centralizes these regulatory identifiers in the Template Registry (/dashboard/marketing/sms/templates), guaranteeing that every outbound text carries approved header hashes and registered content tokens.

Service Implicit (Transactional)	6 Alphabetic (SKYLNE)	24/7 (Anytime)	Site visit appointment confirmations, payment receipts, OTPs. Bypasses DND registries.

Character Counts and Segment Credit Calculation

Telecom operators bill SMS messages based on encoding segments:

Standard GSM 7-bit Encoding (English)

• 1 Segment (1 Credit): Up to 160 characters.
• 2 Segments (2 Credits): 161 to 306 characters (153 characters per segment due to concatenation headers).
• 3 Segments (3 Credits): 307 to 459 characters.

Unicode Encoding (Accented Characters, Regional Languages, Emojis)

• 1 Segment (1 Credit): Up to 70 characters.
• 2 Segments (2 Credits): 71 to 134 characters (67 characters per segment).

Including even a single special character outside standard GSM-7 (such as certain curly quotes or emojis) forces the entire message into Unicode mode, instantly reducing your single-credit limit from 160 characters down to 70 characters.
