Thank you all for your help: Below is a summary First, create a new field in your table. Then, in the Field Calculator, type in the word: rec If you don't want 0 or you want to start at a specific number, do rec+1 or rec+100, etc That should give all polygons a sequential ID. Thanks Lori and Pieta. There were other routes to complete this task but this one is the easiest and the shortest. Thanks again Anthony B.
