Traveling Mailbox vs St. Brendan's Isle: overview
Traveling Mailbox
Most PO-box-style virtual addresses only accept USPS mail, but Traveling Mailbox's roughly 50 US addresses are real street addresses that take deliveries from USPS, UPS, FedEx, and DHL alike, a meaningful distinction for anyone who orders through private carriers regularly. Travis Poole built the company in Sanford, North Carolina in September 2011, aimed specifically at travelers, RVers, expats, military personnel, and digital nomads; operations have since moved to Orlando, Florida. Every plan includes scanning by default, and a mobile app lets customers decide what happens to each individual piece of mail as it arrives.
St. Brendan's Isle
No annual dues, no sign-up fee, and straightforward month-to-month billing set St. Brendan's Isle apart from most of this category's contract and subscription structures. It began in Green Cove Springs, Florida in 1988 as a mail-forwarding service for live-aboard cruisers, and has since grown to more than 3,500 clients worldwide, largely by word of mouth within the cruising and RV communities. The company provides a genuine street address but stops there: no DMV packet, no Declaration of Domicile filing, no registered-agent service, so establishing residency itself remains entirely the customer's own process.
