Anytime Mailbox vs St. Brendan's Isle: overview
Anytime Mailbox
Founded in 2013 and based in Henderson, Nevada, Anytime Mailbox operates the same marketplace model as iPostal1, built on independent partner mail centers instead of company-run facilities. Its own materials describe a network north of 2,000 locations in over 40 countries, though an older crawl of its About page shows a smaller figure closer to 770, a gap more likely explained by growth between snapshots than a contradiction, but worth noting as a source-dependent number rather than a fixed one. Because every partner sets its own rates, pricing and scan fees genuinely differ from address to address, which makes budgeting less predictable than with a flat-rate operator.
St. Brendan's Isle
More than 3,500 clients worldwide currently use St. Brendan's Isle, a figure the company has built up since 1988 with no annual dues, no sign-up fee, and a straight month-to-month billing structure that's unusual in this category. It began life as a mail-forwarding operation for live-aboard cruisers out of Green Cove Springs, Florida, and that origin still shows in features like inactive-status account holds, which let a customer who travels only part of the year pause billing without losing their address. What it won't do is anything beyond the mail itself: no DMV packet, no Declaration of Domicile paperwork, no registered agent. A customer establishing residency is on their own for that part.
