AWS End User Messaging Enables International SMS via US Toll-Free Numbers AWS End User Messaging has introduced a new feature that allows businesses to send SMS messages to over 150 countries using a single US toll-free number (TFN). This capability simplifies global messaging strategies by eliminating the need to procure country-specific numbers, making it particularly useful for businesses sending transactional alerts like one-time passwords (OTPs) or shipping notifications. The feature is backward compatible, meaning it can be enabled on both new and existing US toll-free numbers through the AWS console or AWS CLI.
