I went to DakotaPost this morning, since I happen to be in their home town, and told a woman there about the email I'd received from Wells Fargo. She knew all about the issue, having heard from many other DakotaPost customers, and this is what she told me.
Although DakotaPost is fully compliant with the current Patriot Act (as I expect the Escapees Mail Service is), all the big banks are starting to crack down on customers with P.O. boxes or Personal Mail Boxes. In Wells Fargo's case, this just began yesterday, she said. She reeled off the names of half a dozen major banks that have sent out similar notices to DakotaPost customers. Wells Fargo was one; I recognized the others, but don't remember them all. According to her, the only bank that hasn't pulled this "you must have a physical residence address" requirement (yet, I said to myself) is U.S. Bank.*
She went on to say that at this point I have two choices: move my money to U.S. Bank, or find a relative or friend who's willing to let me use their home address as a "front" in order to satisfy Wells Fargo's new requirement.
While I feel like giving WF the finger by moving my money elsewhere, I can easily imagine that U.S. Bank will probably be sending out similar notices sooner or later. So I'm going to ask a friend to front for me, which is stupid and annoying... but what else can I do?
DakotaPost is a large, well-established mail forwarding service, so I'm sure they have plenty of customers who are affected. In fact, the woman told me that many of their customers bank with Wells Fargo. If what she said about all the major banks doing this is correct, I expect a lot of unhappy full-timers will be hearing from their banks in the near future.
* I hadn't heard of them, but Wikipedia says they are the fifth largest banking institution in the United States.
