+In short, yes you can use user assigned managed identities in more than one Azure region. The longer answer is that while user assigned managed identities are created as regional resources the associated [service principal](../develop/app-objects-and-service-principals.md#service-principal-object) (SPN) created in Azure AD is available globally. The service principal can be used from any Azure region and its availability is dependent on the availability of Azure AD. For example, if you created a user assigned managed identity in the South-Central region and that region becomes unavailable this issue only impacts [control plane](../../azure-resource-manager/management/control-plane-and-data-plane.md) activities on the managed identity itself. The activities performed by any resources already configured to use the managed identities would not be impacted.
