- Getting the physical mail out of them was hard. In theory they kept main for some number of days if I needed it physical for some random reason, but the two times I needed to have them forward me some important document, it had already been shredded. All in all, this was a minor edge case really.
- One company, All State, could not for the life of them realize that I did not live in some PO Box in a different state. They kept changing my rates to the state of the service, and I had a confusing call with a CSR each time where I tried to explain my mailing address and my residential addresses were unrelated. All State was the only company I ever encountered with this issue, everyone else that needed my home address had no trouble with this concept. I solved this by ditching All State.
I only stopped using them because they got bought out and only kept business accounts. I should look for a replacement company, it was very useful.
Similar to how phone numbers can be tagged VoIP and won’t be accepted for 2-factor authentication.
Found them because they cater to the RV and cruising (sailing/motoring around the world) folks, and that's my circle of friends.
