Requesting sender IDs for SMS messaging with Amazon Pinpoint

In SMS messaging, a sender ID is a name that appears as the message sender on recipients' devices. Sender IDs are a useful way to identify yourself to the recipients of your messages.

Support for sender IDs varies by country. For example, carriers in the United States don't support sender IDs at all, but carriers in India require senders to use sender IDs. For a complete list of countries that support sender IDs, see Supported countries and regions (SMS channel).


Some countries require you to register sender IDs before you use them to send messages. Depending on the country, this registration process might take several weeks. The countries that require pre-registered sender IDs are indicated in the table on the Supported Countries page.

If you're sending messages to recipients in a country where sender IDs are supported, and that country doesn't require you to register your sender ID, you don't have to perform any additional steps. You can start sending messages that include sender ID values immediately.

You only need to complete the procedures on this page if you plan to send messages to a country where registration of sender IDs is required.


If you plan to send messages to recipients in a country where sender IDs are allowed but not required, you don't need to open a case in the Support Center. You can start sending messages that use sender IDs immediately.

Special requirements for sending SMS messages to recipients in India

By default, when you send messages to recipients in India, Amazon Pinpoint uses International Long Distance Operator (ILDO) connections to transmit those messages. When recipients see a message that's sent over an ILDO connection, it appears to be sent from a random numeric ID.

If you prefer to use an alphabetic sender ID for your SMS messages, you have to send those messages over local routes rather than ILDO routes. To send messages using local routes, you first have to register your use case and message templates with the Telecom Regulatory Authority of India (TRAI). These registration requirements were designed to reduce the number of unsolicited messages that Indian consumers receive, and to protect consumers from potentially harmful messages. This registration process is managed by Vodafone India through its Vilpower service.


The price for sending messages using local routes is shown on the Amazon Pinpoint pricing page. The price for sending messages using ILDO connections is higher than the price for sending messages through local routes. Currently, the price for sending ILDO messages is USD $0.02171 per message.

To complete the registration process, you have to provide the following information:

  • Your organization's Permanent Account Number (PAN).

  • Your organization's Tax Deduction Account Number (TAN).

  • Your organization's Goods and Services Tax Identification Number (GSTIN).

  • Your organization's Corporate Identity Number (CIN).

  • A letter of authorization that gives you the authority to register your organization with Vilpower. The Vilpower website includes a template that you can download and modify to fit your needs.

Vilpower charges a fee for completing the registration process. Currently, this fee is ₹5900.

To register your organization with TRAI

  1. In a web browser, go to the Vilpower website at

  2. Choose Signup to create another account. During the registration process, do the following:

    • When you're asked to specify the type of entity that you want to register as, choose As Enterprise.

    • On the Select your Telemarketer page, for Telemarketer Name, choose Infobip Private Limited – ALL. Please note that the dropdown list is not organized alphabetically. Instead of scrolling, start typing the telemarketer name to retrieve a list of names matching the typed criteria.

    • For Enter Telemarketer ID, enter 110200001152.

    • When prompted to provide your Header IDs, enter the sender IDs that you want to register.

    • When prompted to provide your Content Templates, enter the message content that you plan to send to your recipients. Include a template for every message that you plan to send.

  3. Complete the steps at Requesting sender IDs to request a sender ID for India. In your request, provide the Entity ID, Unique Header IDs, and Template IDs that you received during the registration process.
