Nomad's Travel Talk - Passports, Visas and Mail Handling

I use anytime mailbox. Virtual mail. Works well.

I use the ipostal1.com mail collection but once a month I need to consolidate into 1 big packet and get it mailed to me. Instead of going to a homeowner’s home, I would like it sent to the US postal service General Delivery and was wondering if anyone has done this and if it’s a good system for full time travellers. I had tried using this before and the postal service location told me I couldn’t use it unless I registered first in that county.
