i applied for USPS Web Tools ID and i followed all the steps on http://manual.aspdotnetstorefront.com/p-378-usps-address-verification.aspx but it is not working.  

Any chance someone knows what I might be missing?

- i submitted this form: https://www.usps.com/business/webtools-address-information.htm

- i filled out all appconfigs

- i spoke to USPS and verified that my Web Tools ID is in 'production' mode

- i am not using one-page checkout

when is the address validation supposed to take place?  does it happen on the edit/add address page or just when you click 'submit order'?  

- i am not using real time shipping, does that matter?


thank you for any help!

i spoke to USPS again and they verified that my ID is in production mode but they said i was not yet setup for address verification.  they set me up for that, but it still does not work on my site.

i also got an email from USPS saying:

The URLs you will use for the Production Servers are:


i'm wonding if i should try using https://secure.shippingapis.com/ShippingAPI.dll

Hmm, Jim I would compare those servers to the ones in the AppConfigs for the service, but if you are on the latest MSx, the ones there should be ok. But yes, wouldn't help to check and possibly update (but save the previous values). 

I'm guessing once USPS approves you for the Address Verification services, it will work fine...

Thank you,

do you know how this is supposed to work?  i tried checking out with an incorrect address and nothing happen, it doesn't seem to work.  at what stage in the checkout process should i see an error that corrects my address?
