Yes you could do this in a couple ways:
1. Linkedin company enrichment: this will pull in the number of locations a company has posted on their linkedin profile
2. depending on your industry, there may be some websites that you can use a scraper to find (eg: Glassdoor)
3. Use an API key for Apollo and pull in the number of retail locations
It could be, I'm not 100% sure on apollo's API limitations by plan. I was using their pro plan before but it could work on basic. worth a try!Hmm if they are big enough, they probably have linkedin - I would recommend testing that out on a handful of sample companies to see how good the results are.
