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).

Complete the LOAs

Most operators in Indonesia require an LOA to be signed and stamped. This LOA authorizes Twilio, Inc., to register and send branded SMS messages on your behalf.

Each LOA includes an English and a Bahasa Indonesian section. Please fill out both sections.

• If the Sender is based in Indonesia and has a materai, use the Domestic LOAs in the Domestic Customer Templates subfolder in the Indonesia Customer Documents folder you have downloaded. 
• If the Sender is based outside Indonesia, use the International LOAs in the International Customer Templates subfolder in the Indonesia Customer Documents folder you have downloaded. 

Each LOA requires the following information: 

• Sender company’s letterhead
• Alphanumeric Sender ID requested
• Sender company’s nature of work/industry (e.g., Information Technology, Retail, Transportation, Consumer Goods)
• Title and name of Sender’s authorized signatory (e.g., CEO, CFO)
• Signature of authorized signatory
• Sender company stamp
• Sample message template
• Sender materai (As of 2021, the value indicated should be 10,000 - ensure that this is present, and that all 3 parts are overlapping one another)

Note: We strongly recommend that you download the examples below as images and follow them, field by field, when filling out the LOAs. We would also like to note that effective 2021, there is a revision in the meterai stamp cost, and we request that you verify the needed stamp amount beforehand.
