How to find differences between the same two point layers

NancyBracken — Tue, 03 Mar 2026 16:03:38 GMT

So I am still learning and I need some help. I have two of the same layer which is Address Points. I have one more in the one layer than the other, how can I find where the difference is between those two layer.

you could try

Add Join (Data Management)—ArcGIS Pro | Documentation

assuming that you have a common field or fields in both. Pay attention to the parameter

Keep all input records

I think the erase tool may help to some extent also. That might indicate which one is not the duplicate but I would need to test that.

Another option is to run the frequency tool on both datasets and do a comparison that way.

Otherwise, assuming the addresses have matching values, @DanPatterson recommendation would be best.

The Feature Compare (Data Management) GP tool compares two feature classes or layers and returns the comparison results. It works against geom etries, attributes, schema's and more.
