The TCCCPR is TRAI's Telecom Commercial Communications Customer Preference Regulations, 2018. It sets the rules for commercial SMS and calls in India: senders must register, use registered headers and content templates, respect customers' preferences and consent, and keep to category rules. Operators check every message against these records, and senders who break the rules can lose their telecom resources.
By Rohit Jadhav. Last reviewed 25 October 2026. This is operational guidance, not legal advice. We summarise a consolidated copy of the regulations published by TRAI, and the gazetted text prevails over any consolidated version.
Almost everything in DLT comes from one document. When a portal asks for a header, when a template is rejected, when a message is scrubbed, the rule behind it sits in the TCCCPR. This guide reads it in plain words: what it covers, the ideas you need, the limits that affect everyday sending and the consequences for breaking it. It is part of our main guide to DLT registration in India. If you want a provider that handles the compliance side, see Nexcomm's bulk SMS service. More guides sit under Compliance & Regulations.
What is the TCCCPR?
It is a regulation made by the Telecom Regulatory Authority of India to protect customers from unsolicited commercial communication and to let them choose what they receive. "Commercial communication" is defined as any voice call or message where the primary purpose is to inform about, advertise or solicit business for goods or services, a supplier of them, or a business or investment opportunity. TRAI publishes a consolidated copy of the regulations on its website, which is the version we read.
What are the key ideas?
- Sender and header. A sender registers and gets headers, the names a message is sent under. See SMS sender ID.
- Content templates. Every message follows a registered template with fixed and variable parts. See DLT template variables.
- Categories. Transactional, service, promotional and government messages are treated differently. See transactional vs promotional SMS.
- Preference register. Where customers record what they block. See DND SMS rules.
- Consent register. Where consent given to senders is recorded. See SMS consent in India.
- Scrubbing. The check of your list against both registers. See DLT scrubbing.
What limits does it set that you will notice?
- Commercial communication is allowed only through registered headers and numbers allotted for the purpose.
- A usage cap: an ordinary telephone number may make at most twenty outgoing calls and twenty outgoing messages a day.
- Promotional messages must give an opt-out in the same message.
- Promotional content mixed into a transactional or service message makes the whole message promotional.
- More than three variables in a template needs special justification, and a template is not linked to more than one header.
- After a customer revokes consent, the sender can seek it again only after ninety days.
- Unused content templates may be temporarily deactivated after ninety days.
What are the consequences of breaking it?
Operators act on complaints. The regulation provides, for a sender found to have sent unsolicited commercial communication, that outgoing services of all the sender's telecom resources are barred for fifteen days for the first violation, and for repeated violations the resources are disconnected for one year. Registrations and templates can also be suspended. These are not theoretical: they apply to the numbers and lines you use, not just the campaign.
Does it apply to political messages?
The regulation's definition of commercial communication is about goods, services and business opportunities, and its text does not name political messages. How a party's SMS is handled is decided in practice by the operators that review templates. We explain what that means for campaigns in our guide to DLT registration for political party sender IDs.
A worked example (hypothetical)
A tutoring company in Bhopal wants to know why its messages fail. This is an invented example. It reads the TCCCPR in sections. It finds that its "fee due" message also advertises a new course, which makes the whole message promotional. It finds that the promotional message has no opt-out. And it finds that two of its templates share a header it did not register for them. It splits the messages, adds an opt-out, registers each template against one header and keeps consent records for its lists. Failures drop, and complaints stop.
Common mistakes about the TCCCPR
- Assuming the rules apply only to big senders. They apply to any commercial sender.
- Reading a summary and not the text. The consolidated regulation is the reference.
- Treating a vendor's assurance as compliance. The sender is responsible.
- Ignoring complaints. They trigger action.
- Forgetting amendments. TRAI amends the regulations, so check the current consolidated copy.
