Zip code boundaries

[SavitriDevisetty]

Hello,

Is there a way in arcGIS Silverlight API that I can provide a zip code and then get a polygon to be drawn on the map?

Thanks for your help in advance.

Thanks!

Basically, you need to run an attribute query against the polygon feature layer consisting of polygons representing various zip codes. You can follow this online sample

Hello,

Thanks a lot for the reply. I understand that we got to create a feature layer with polygons that represent zip codes. But right now I am using the arcGIS online map services for my sample application (haven't bought any services or products from ESRI) and want to see if ESRI has any free web service which would give me a list of polygons based on zip codes. We are in a stage of prototyping and can't buy anything.

Your help in this regard is appreciated a lot.

Thanks!

You can search argis.com. While this is not a service, I think you are attempting to do something similar: http://redlandsbaoapp1.esri.com/ZipCodeLookup/Default.aspx. If you run Fiddler, you will see what services they are using. I think SDS and Demographics.

Hello,

Thanks a lot for the information, it worked great for me. Another question I have is, is it possible to get polygons based on 5 digit zip code and next 4 digits too (zip+4). Does ESRI have a web service which would give me these granular polygons.

Thanks a lot for your help in advance.

Thanks!
