Go to Settings > States & Provinces to configure the State/Province drop down list that displays on the address form in Rev.io. By default the options for the United States and Canada are populated.

A state or province can be deactivated by clicking the Edit link on the state/province list. This means it will still be stored in your system, but no longer is selectable on the address control. For the US, Lifeline options can be configured as well.
