In this example we have a map with the location of Jack Demsey’s in New York City. By using the buffer functionality of the GIS app we can find all the ZIP code areas within 1 mile from the restaurant. Below you can find a step-by-step guide on how to create a 1 mile buffer around the restaurant and how to create a filter to only select the areas within this 1 mile radius.

Quick tip: Create a list of ZIP codes within a specific radius

If you want to create an Excel/CSV list with all the ZIP codes within a specific radius please use the export option with that particular filtering option turned on. This allows you to create a list of all ZIP codes within a radius.

Find ZIP codes in multiple radii

In this example we have a map with multiple business locations in New York City. Below you can find a step-by-step guide on how to create a 1 mile buffer around every location plus how to create a filter that only shows ZIP code areas within that particular radius.
