Dwolla appears to be based somewhere near Des Moines, Iowa. Their phone number is in the 515 area code. When I called it (after hours), I got their voice mail, which indicates that they are open between 9:00 AM and 6:00 PM "Central Time zone". Jordan Lampe, their "Director of Communications", has a Twitter account that lists him as being in Des Moines, Iowa. HOWEVER, their domain (dwolla.com) is registered through Domains by Proxy, GoDaddy's Whois Privacy service, which means that there is no way to verify a postal address or actual location for the domain doing business as Dwolla. And with VOIP, phones in any area code can point to any phone in the world. Although I think it's unlikely that they are not located in the U.S., they could theoretically be anywhere. That's *really* cheesy for a financial company or any company that wants to build trust.

I've been using Dwolla. The whole Bitcoin economy is new, so I'm careful. Nobody can drain an important bank account of significant sums through it because I opened a separate bank account to use with it and other Bitcoin-related businesses, and keep very little money in it. I highly recommend that others take the same precaution, even if you end up paying a fee for use of the account. You should NOT risk more money than you can afford to loose on Bitcoin til it has matured significantly.
