Object ID in Collector (Offline map) different from Hosted Feature layer

Anonymous User

I have a hosted feature layer in ArcGIS Online that data is collected using QuickCapture and Collector. I have Map Areas created for Collector for offline use. In the Web Map I have the points labeled by Unique ID however the IDs change once downloaded to Collector. I also have a view of the data being used in another Web Map also used in Collector labeled similarly. The ID's in the Web Map with the view also change once downloaded. The IDs differ even between the two downloaded maps. 

Has anyone came across this discrepancy or have any solutions?

Thanks!

That kind of makes sense since when you go offline it creates a check out replica on the device.  Whenever you create a new dataset Arc starts objectid back at 0.

ObjectIds can change for all kinds of reasons.  I suggest not using that as your ID.

Hope that helps.
