UPS Shipping Module

[WiccanWitch420]

I have Zen version 1.3.8a I use USPS shipping right now.

I just notice there is a UPS shipping module in ny zen, and I was thinking about using it. I will be shipping from the US.
I put it up and then on the site, it gives quotes and everything, but is there a way to check to see if they are accurate? I didn't see a space to enter any key or code (like you have to do on USPS) so I was wondering how it even knows what to quote, if there is no account? Or is this module just super easy>?

I have never shipped UPS before, is there any particular types of the shipping they offer that I should offer, or ones that I shouldnt?

By default it needs a zip or will not estimate

is there a way to check to see if they are accurate?
