I wondered the same thing. I had my daughter mail a letter from California as a test. It was addressed to my full name, Charlotte Mail Center, Box ####, The Villages, FL, Zip. It worked just fine. The reason is I would like to use it as my return address for selling on eBay. It will save me from paying for a PO Box. I still want to talk to our mail gal just to confirm it’s ok on a regular basis.
