I need to know if ACF Pro is my tool for having a Zip Code Lookup number box that when entered will display a Company Name and Address for that zip code entered?
If you look at this website and go down to Contact, you can enter a Zip Code and it display next to it the company name and address. https://www.siaa.net/
If there is a specific “company” that exactly matches the entered values, then ACF could work. To us only ACF this would pretty much require that you enter every zip code that each company covers so that there is a 1 to 1 lookup.
If you are looking for a “radius” type of search, looking for any company that is close to the zip code entered so that you don’t need to enter every zip code, then ACF is probably not the correct choice. There is no functionality in ACF to do this and you’d need to build this yourself. For something like this I would go with the pro or gold addition of WP Google Maps https://www.wpgmaps.com/ or get everything with the developer bundle.
