How to assign a single ID number to two separate polygons (regions?)

SaratogaPLAN — Thu, 06 Mar 2025 15:02:19 GMT

I want to assign a single ID number to two separate polygons. with the result being a single row of data for two polygons. I think this used to be called Regions in Arcmap.

I just cant find the function in ArcGIS Pro.

It is normal in tax parcel mapping to have two or more parcels with a single owner but where the parcels are not contiguous; say separated by a road.

Thanks.

So you want to create a multi-part polygon?

You can merge existing features:

And you can add multiple polygon parts while editing.

Yes, this looks like the new name for the function of " features are composed of more than one physically separated part and only reference one set of attributes. "

I'll try it now.

Thanks!

It looks like Multipart is the solution. Trying it now. Thanks.

The Dissolve tool is the solution. It creates a single record the includes two separate, non-adjacent polygons.
