+## Q: In what cases is the Experience Cloud ID (ECID) reset or cleared?
+
+A: The Identity for the Edge Network extension does not automatically reset or clear the ECID. If you observe the ECID being reset, identify if it falls into one of the following cases:
+
+* Cleared when the app is uninstalled.
+* Reset using the [`resetIdentities`](../../home/base/mobile-core/api-reference.md#resetidentities) API.
+* Reset when the app local persistence is cleared for any reason in the app implementation. To learn more, see where the [Mobile SDK stores identity data](../../../pages/resources/faq.md#where-does-the-sdk-store-identities-and-preferences-on-the-app).

 ## Q: What steps are needed to generate a new Experience Cloud ID (ECID) for a user when using both Edge extensions and Adobe Solutions extensions?
 
 A: Both identity extensions' ECID must be regenerated in sequence to avoid linking the old and new ECIDs in Adobe Experience Platform.
