Using on a Real Estate Site

Hi, I have a real estate wordpress theme, and it doesn’t do postcodes/zip codes… am I right in thinking I could add this to the site and do it by miles from the post code location?

And to link the postcodes to the actual pages you drop in a shortcut to recognise this?

Does this sound right?

Thanks
