  • can't you just add the number after the editing is done. The features seem to go into the table in the order they were digitized and you can populate a numeric field after the fact. See this similar question. gis.stackexchange.com/questions/95249/… – jbchurchill Jan 22 '16 at 15:14

  • I dont agree that this is a duplicate. This question deals with an auto-increment that automatically occurs when a new feature is created. The other post deals incrementing numbers using field calculator which does not occur automatically on a create feature. just my 2 cents – ed.hank Jan 22 '16 at 20:05

I believe you should look into the Attribute Assistant which is located here: http://solutions.arcgis.com/shared/help/attribute-assistant/ - You want to set up the Autonumber

enter image description here

Set the tool to operate "On Create" and it will find the highest number in your [number] field and populate your missing data with the next autoincremented number automatically when you create a new feature.
