Displaying contents based on entered zip code

Hi guys, a quick question,

I have a client who wants to display info using a simple theme, the theme will have a section to display an image, a text and a footer with an address, but he wants to have that info displayed based on an entered zip code, if for example I enter 90210 all the info, the text, the address and the image will be based on Beverly Hills, if I enter 94109 the text image and address will be based on certain area of San Francisco, my question is, how to achieve this? Is there a zip code, even a premium one that allows me to do that?

Thanks guys!
