I have followed the instructions in GIS Tutorial for ArcGIS Pro 2.8 tutorial 8.1 to create a zip code locator for the tutorial (starting pg 241). I followed the instructions to create a locator using PARegionZip and field "ZIPCodeNum" (see LocatorSetup image) and I did not change any of the defaults on the catalog pane.
Next I setup the geocode addreses tool following the instructions (see geocodeSetup image) and when I run the tool I only get 7 matches out of 1,123.
I have tried modifying the tolerance, changing the field used, adding state data, using different zip code layers, and creating a locator in ArcMap and I either get 7 results or none. I am not sure what I am doing wrong and would like some input. All of the files can be downloaded from the books resource page (file is too large to be uploaded).
