Deactivated address types can be reactivated later if you need them again in the future. To reactivate address types:
Go to the System Address Types configuration page. The page consists of three tabs using which you can select whether you want to manage address types for Company, Site or Contact Types. The page displays the options for the Company tab by default.
Click on the tab under which the address type you reactivate is stored.
Select the Show Inactive checkbox to the right of the Types listbox. The page refreshes and the Inactive address types are displayed along with the active ones.
Select the address type you want to reactivate from the Types listbox. Once you do this, the page refreshes and the details of the selected address type are displayed in the respective fields.
Go to the Inactive checkbox and click on it to make it blank.
Click the Save button. The selected address type will be reactivated and will be available under the selected entity.
