Hello Everybody,

Can anybody tell me how to show google map with the help of zip code...I've used latitude and longitude to show it and it works fine....but i want to use Zip code for the map....

Or the application may be like this....that whenever i enter a zip code it will return the latitude and longitude for the corresponding zip code.

Thanx in advance..

Regards---Arindam 

 Google maps doesn't do geocoding (turning lat & long into zip codes and other information) but Yahoo maps does do geocoding.  Another alternative is use an alternative geocoding service and feed the data to Google maps, that will work just as well and your consumers won't know the difference.  Here's a link:

Zip codes as you probably know do not have a single point, they are not even true polygons but rather comprised of collection of streets. So when geocoding zip codes (or cities) the centroid point is usually calculated based on specific algorithm, Google for polygon centroid for more info. 

As far as geocoding services go there are couple web services that do zip code or city geo coding, this one http://codebump.com/subscriptions/ for example or search xmethods.com for "zip code service".
