Map showing customer locations

I am currently working on an app that will show the location of each customer, grouped by dealer, on a map. All I have is the zip codes of the customers. This is my first attempt at creating such a map and I have a couple of questions. Is there a way to either place a marker on a map by zip code or convert the zip code to the necessary coordinates? The zip codes or coordinates are being collected through a SQL query. How do you enter the coordinates into the map so it can display all the point…
