According to USPS regulations, mail carriers cannot be required to use a key to access personal residential mailboxes. In response to this regulation, we have designed our mailboxes to take deliveries without needing a key. Here’s how it works:
Keyless Mail Delivery
- Upper Unlocked Door: Mail carriers deposit your mail through the dedicated upper incoming mail door, eliminating the need for keys.
- Mail Slots or Bins: These strategically designed slots or bins securely capture incoming mail, preventing fishing attempts.


Enhanced Security Features
- Locking Delivery Boxes: Made from robust, vandal-proof steel, these compartments offer an extra layer of protection.
- Secure Patented Anti-Pry Latch: Access your mail using a unique, laser-cut key that unlocks the secure latch. This ensures only authorized individuals can retrieve your mail.
