A Principal Entity (PE) is a business, organisation or individual that sends commercial communications to subscribers.

Under India's Telecom Commercial Communications Customer Preference Regulations (TCCCPR), applicable entities must comply with the relevant DLT registration, header and content template requirements established by telecom access providers.

A registered Principal Entity works with registered telemarketers and uses applicable registered SMS headers and approved message templates to send commercial communications.

A Principal Entity ID, also known as a PE ID, is a unique identification number assigned to an entity during its registration on a DLT platform.

Businesses may need their PE ID when managing DLT registration, coordinating with telemarketers or handling SMS header and content template registrations.

An SMS Header is a registered sender identifier used to identify the origin of commercial SMS messages.

Businesses use registered SMS headers for permitted communication such as transactional notifications, service updates and other applicable message categories.

SMS headers are associated with Principal Entities through the DLT ecosystem and are subject to the applicable registration requirements.
