What do I get with my free 21-Day ArcGIS trial?
What happens at the end of the trial?
Once your trial has ended, you can call Esri to purchase. Provide your trial subscription ID, and all the work you've saved in ArcGIS Online becomes part of your new paid account. You won't lose anything you have built.
Please note: Trial subscriptions are for nonproduction use only. Trial subscriptions from multiple individuals and the content they create during the trial cannot be merged into a single ArcGIS Online subscription.
