Depending on the reason, you will likely need to access local business directories, map APIs, or utilize data scraping tools to acquire business listings with geocodes (latitude and longitude) for a given area.

1. Use Google Maps API or Bing Places API

With business Google Map and Bing Places APIs, you can search for and retrieve classified businesses within a particular area, and they will return the results indicating business titles, locations, addresses, and geocodes. Of course, a developer key is a prerequisite.

2. Third-party Data Providers

Other websites, for instance, Data Axle or Yelp, Foursquare API, do provide their business datasets with geocodes but usually for a price.

3. Scraping Local Directories with Permission

Some public directories, for example, EZ Local, show businesses with their city and state but do not provide geocodes. However, if the business or geocoding address is offered, you can apply geocoding APIs for translating the address to latitude and longitude, such as Google’s.

Note:

Always check the conditions of service of sites such as EZ Local concerning their data policies before scraping or programmatically extracting data.
