Nearest Store Location

Hey,
Im creating an app through unity. I found this the best way to do it, as its mainly an AR app and i like the way unity handles AR.
I want another section on the app where people would be able to enter their postcode and it would tell them their nearest branch/store.
Does anyone know how i would go about this?

Cheers

Not sure how to convert a postcode to a location, but with just unity you can activate the phones location service and get geographic coordinates and compare the distance to a list of known stores locations

Something like that is how I previously solved this problem with mySQL. You could probably weld together something like this with a local SQLite database if you wanted [it’s free], or just make it a server side API call [low cost and simple]. This method might be better for store locations than zip codes, as there will probably be a lot less of stores then zip codes, but you can find zip code lists with GPS tags online too.
