 ### Can I change my AWS Account ID?
 You are only able to configure one AWS Account ID per source. Once you've configured your Amazon EventBridge destination with an AWS Account ID, it is not possible to modify it. If you do need to change the AWS Account ID for any reason, you will need to create a new Segment source and configure a new destination.

+As an alternative, you can use a [Repeater destination](https://segment-docs.netlify.app/docs/connections/destinations/catalog/repeater/) to your existing source, which will repeat the events through the new source you create. This new source can then be connected to a new EventBridge destination which can be configured with a new Account ID in the settings.
