When using Amazon Simple Notification Service (Amazon SNS) to send text messages (SMS) to your customers, you now have the option of selecting the origination number to use. Origination numbers are the phone numbers that Amazon SNS will use to send your SMS message, such as short codes and long codes.

Amazon SNS is a highly available, durable, secure, fully managed pub/sub messaging service that enables you to decouple applications and to send notifications to end users using mobile push, SMS, and email. With Amazon SNS, you can send SMS text messages to 200+ countries for use cases such as multi-factor authentication (MFA), one time passwords (OTP), application notifications, and marketing messages.

By specifying the origination number for SMS messages, you can achieve a more consistent and trusted experience for the message receiver. Additionally, by purchasing multiple origination numbers, such as short codes or long codes, and selecting the origination number, you can control which numbers are used for various use-cases or implement load sharing approaches that better suit your needs. To select an origination number, you must have one or more short codes or long codes configured in your AWS account for the specific destination country.

This feature does not apply when sending SMS to countries where local limitations, laws, or regulations require the use of Sender Ids in the place of origination numbers, for example India. The ability to select the origination number is available in all AWS regions where you can send text messages using Amazon SNS.
