The ArcGIS suite is provided by joint funding from the College of Agriculture & Environmental Sciences and the Office of the Provost.
Policies & Guidelines:
Don't Do Bulk Geocoding on ArcGIS.com
You have 500 credits to start with. Please use them judiciously. Everything uses credits on ArcGIS.com, but Bulk Geocoding is particularly expensive. Bulk geocoding (placing more than 1000 addresses or place names from a table on the map) SHOULD NOT be done through ArcGIS.com. For more information about how ArcGIS credits are used see https://doc.arcgis.com/en/arcgis-online/reference/credits.htm
