# Using the Default Namespace in Organizations with No Namespace Set

If your organization hasn’t set a namespace prefix, use the default namespace `c` when referencing Lightning components that you’ve created.

The following items must use the `c` namespace when your organization doesn’t have a namespace prefix set.

-   References to components that you’ve created
-   References to events that you’ve defined

The following items use an implicit namespace for your organization and don’t require you to specify a namespace.

-   References to custom objects
-   References to custom fields on standard and custom objects
-   References to Apex controllers

See [Namespace Usage Examples and Reference](https://developer.salesforce.com/docs/platform/aura-platform/guide/namespace-using-reference.md#namespace-usage-examples-and-reference) for examples of all of the preceding items.
