Regional availability
The AWS End User Messaging SMS and Voice version 2 API Reference is available in several AWS Regions and it provides an endpoint for each of these Regions. For a list of all the Regions and endpoints where the API is currently available, see AWS Service Endpoints and Amazon Pinpoint endpoints and quotas in the AWS General Reference.

In each Region, AWS maintains multiple Availability Zones. These
Availability Zones are physically isolated from each other, but are united by private,
low-latency, high-throughput, and highly redundant network connections. These
Availability Zones enable us to provide very high levels of availability and redundancy,
while also minimizing latency. To learn more about the number of Availability Zones that
are available in each Region, see AWS
