Mail Boss Locking Security Mailboxes

Family owned and operated since 1997

Epoch Design launched the Mail Boss locking mailbox in 2006, in response to the epidemic of mail-identity theft. The vision of the Mail Boss brand is to offer Americans a secure and affordable solution to stop mail thieves. The original Mail Boss quickly won over consumers and retailers alike with its heavy-duty construction, and innovative security features and has since grown to include dozens of products with significant structural and durability improvements in a range of styles and colors.
