Creating a Custom Command

Within your AccuZIP software is a command section that can be personalized for your specific needs for data hygiene and mail processing. Below are some common commands requested by new users. You can find more common commands on the Commands page here on our website.

To use a command [create a command], have a list imported into AccuZIP and showing on the main screen. Go to Edit > Commands in the drop-down menu at the top of your AccuZIP screen. Once there, you can add any command simply by choosing the icon that resembles a sheet of paper on the right side of the Command screen to open the Create and Run a Command window.Simply give your custom command any name that you prefer. AccuZIP6 saves your new command so it will be available in the drop-down menu for future use. Add your custom command to the command Statement syntax area:
