Before we begin
Due to regulatory requirements, there is sometimes a need for documents to be signed by customers to ensure that registrations are done on behalf of customers that have the right to use the Sender ID. This serves to ensure that traffic is coming from legitimate sources and minimizes any potential misuse.
This article outlines the documentation requirements for a pre-registration in Indonesia.
Things to note:
1. Physical Stamp known as materai, along with company stamp and stamp required for Domestic
All domestic entities in Indonesia are required to authenticate their documents with a physical stamp known as a materai, along with company stamp and signature. As of 2021, the value indicated should be 10,000 - ensure that this is present, and that all 3 parts are overlapping one another (this is a requirement)
2. Latest Telkomsel Domestic OTP SMS Policy
Requirement for Brand inclusion in OTP SMS
We hereby reiterate the importance of including the name of the brand/service/program/community in the message format for every submission of OTP SMS, as per the sender ID request. This measure is essential to mitigate the misuse of Domestic Sender IDs for international traffic.
Effective Monday, 1 April 2024, any SMS OTP without the inclusion of the brand name in the message format will face automatic blocking via our system if identified as sending International SMS A2P (OTP).

Each LOA requires the following information:
