Can ArcMap create new polygon shapefiles based on the old polygon + all adjacent polygons to the original?

Good morning!


For economic analysis purposes, I'm hoping to utilize an existing polygon shapefile I have of all ZIP codes in the United States to create a new shapefile with polygons for all zip codes and any directly adjacent zip code areas. The total number of polygons shouldn't at all change, they should just each be larger and overlapping. Is this possible to do within ArcMap? If not, what are some steps I could take to create something similar?


Feel free to ask for clarification if any of that doesn't make sense, and I apologize if that's a pretty basic question.

Any advice is appreciated!
