Phoenix is accredited by the Higher Learning Commission [http://www.ncahlc.org/#ncahlc.org] by which other schools in the region are accredited, e.g. University of Michigan.
I stand happily corrected if this is true. Though I've heard numerous UoP grads complain they can't get their credits transferred to their school when they go back for an M.S./M.A.
(but I'm perfectly willing to accept that it could just be sour grapes for not being accepted to get in)
While it is true that you credits will get sliced and diced if you transfer (this is somewhat true of any transfer, but more so with UOP), they are accredited and if you complete you degree at UOP you can go on to be considered for a Masters program at any regionally accredited school. Most state schools and many private collage are regionally accredited. So if one plans to bank a bunch of credits at UOP and then transfer to get a "better" degree they should reevaluate their plan. If ones plan is to Bachelor at UOP and then Master at another school, then so long as their GPA and GRE/LSAT/WHATEVER is up to par, they should have no issue with accreditation.

Specific Phoenix programs are also accredited by the usual suspects as well. [http://www.phoenix.edu/about_us/accreditation.html]
