Regional Data Considerations

Amazon Cognito user pools are each created in one AWS Region, and they store the user profile data only in that region. They can send user data to a different AWS Region, depending on how optional features are configured.

  • If the default no-reply@verificationemail.com email address setting is used for routing verification of emails addresses with Amazon Cognito user pools, emails are routed through the US West (Oregon) Region.

  • If a different email address is used to configure Amazon Simple Email Service (Amazon SES) with Amazon Cognito user pools, that email address is routed through the AWS Region associated with the email address in Amazon SES.

  • SMS messages from Amazon Cognito user pools are routed through the closest AWS Region that's supported by Amazon SNS worldwide SMS delivery.

  • If Amazon Pinpoint analytics are used with Amazon Cognito user pools, the event data is routed to the US East (N. Virginia) Region.
