You can add credits to your account at any time. When you add credits, it automatically extends the expiration date for your existing credits to the new date (credits expire one year after the most recent purchase date).
To purchase credits, click the Buy Credits link in the My Account pages. A new window opens that steps you through the purchasing process.
If you prefer, you can also place your order by calling ESRI Telebusiness at 800-447-9778 (U.S. orders only).
