I have parcel data for a city where my goal is to merge rows which have the same parcel number ID. I have 53,000 total parcels, with about 6 thousand rows that have one duplicate. So far I have been manually merging rows, but now realizing it will take me forever to match these 6,000+ pairs of data. I've attached a screenshot below of one example. I am wondering if there is a code that exists that will merge certain rows based on a duplicate value in one field? I ran a script in the 'test' field that shows me which values have the same parcel number. Now I need to merge these matching values via the 'parcelnumb' field.

This screenshots shows highlighted OBJECTID 46505 and 50818 with matching parcel number fields.

Dissolve your features. Your original parcel data is the input, and use 'parcelnumb' as the dissolve field. Make sure multipart features are allowed (this is the default).
