Requesting sender IDs for SMS messaging with Amazon Pinpoint


Amazon Pinpoint has updated their user guide documentation. This page may no longer have the most up-to-date information. To get the latest information regarding how to create, configure, and manage your Amazon Pinpoint SMS and voice resources, see the new Amazon Pinpoint SMS user guide.

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.

Considerations for a Sender ID

When you are creating a Sender ID you should consider the following:

  • Choose a Sender ID that matches your company branding and SMS service or use case

  • Numeric-only Sender IDs are not supported

  • Amazon Pinpoint Sender ID supported characters (some countries may override these):

    • No special characters except for dashes (-)

    • No spaces

    • Valid characters: a-z, A-Z, 0-9

    • Minimum of 3 characters

    • Maximum of 11 characters

  • If the country you're sending to requires registration you must submit a registration for each AWS Region you plan on sending from
