The OFAC Block List is a module that can be updated from the government website that contains a list of people and entities that you have to check your buyers against to make sure you can sell them a unit.

The names can be searched by scrolling down the list or typing in some of their name and clicking the search last name button. Make sure to look in the A.K.A. list as well.

The update button will download a new list and update this file (you will need to have internet connection and have the proper path setup in your company setup file)
