Creating a Namespace in Your Organization

Create a namespace for your organization by registering a namespace prefix.

If you’re not creating managed packages for distribution then registering a namespace prefix isn’t required, but it’s a best practice for all but the smallest organizations.

To register a namespace prefix:
  1. From Setup, click Create | Packages.
  2. Click Edit.

    This button doesn’t appear if you’ve already configured your developer settings.

    Note

  3. Review the selections that are required for configuring developer settings, and then click Continue.
  4. Enter the namespace prefix you want to register.
  5. Click Check Availability to determine if the namespace prefix is already in use.
  6. If the namespace prefix that you entered isn’t available, repeat the previous two steps.
  7. Click Review My Selections.
  8. Click Save.
