Synchronize Postal Code Extension
This setting allows you to choose if you would like to add zip4 postal code extensions to all addresses. By default zip4 will be added to all adresses. While we recommend including the zip4 postal code extension, as it improves deliverablity, we understand some users prefer not to include this. To disable the zip4 postal code for all addresses, click the cog shaped icon in the upper right corner of your Data Stewardship Dashboard to access the integration settings page.
Once you have selected your zip4 preference, make sure to click the save button in the upper left corner of the integration settings page. You can return to your dashboard by clicking the green leaf above the save button.
