Zip Code to Address Service?

[jeanpaul1979]

Hi, I recently noticed a form that populated addresses based on the Zip Code entered. I have a form that I want to us this with too...

Can someone tell me, how do I do this? Which services are out there that can do this?

I think you want it the other way around. When enter the address, you want it to populate the zip code right?

If that's what you're looking for then I'm sure it would need a city/state to key it off of as well.

Or, are you looking for some sort of AJAX form that starts to populate the street as you type?

Find a database on the nets (it is possible to find all US zip codes to states cvs) and have your dev import and pull info from it.

USPS releases a updated zip data base on regular intervals

I think he's talking about inputting the zip code and it populates the city and state.
MotionX GPS for the iphone does this and it saves a lot of typing when you're on a smartphone.

I ended up making it by following this tutorial:
Using AJAX to get city and state from zip code » Forums, Blogs, Wikis

Really easy to do if you have some programming skills.

That sounds like a seriously bad idea. Cities regularly share the same zip code. What I'd do is plug into the google geocoding api and then offer a dropdown of the results it gives you.
