The US Mail Lock solution is a game-changer for secure mail delivery. With the ability to track and verify the identity of mail carriers, you can rest assured that your important documents and packages are in good hands.
According to the US Postal Service, mail theft is a significant problem in the United States, with over 100 million pieces of mail stolen every year. This is where US Mail Lock comes in, providing an extra layer of security to prevent mail theft and protect your valuable items.
US Mail Lock solutions are designed to be easy to use and require minimal setup, making it simple to integrate into your daily routine. You can even customize your lock to fit your specific needs, whether it's for a home, business, or mailbox.
By using a US Mail Lock, you can enjoy the peace of mind that comes with knowing your mail is secure, and you can focus on more important things.
Lockbox Solutions
Lockbox Solutions are designed to provide a secure and convenient way to receive and send mail and packages.
You can rent a lockbox from the US Postal Service, which can be installed at your home or business.
A lockbox is a secure container that can be accessed by postal workers using a key or combination.
The USPS offers various lockbox solutions, including the PO Box and the Lockbox 101.
The PO Box is a more traditional option, while the Lockbox 101 is a digital solution that allows you to manage your mail online.
With a lockbox, you can receive mail and packages 24/7, without having to be physically present to sign for them.
This is especially useful for people who have busy schedules or live in areas with limited postal hours.
The USPS also offers a range of features with their lockbox solutions, including package tracking and delivery confirmation.
This allows you to stay on top of your mail and packages, and ensure that they arrive safely.
Electric Lock Activation

Electric Lock Activation can be achieved through USPS-provided locks, specifically the USPS Key Lock, which can be integrated with an electric switch.
This setup allows for easy access without the need for a separate building key, making it a convenient option for mail carriers and building residents alike.
The USPS Key Lock can be connected to an electric switch, which then triggers the door's electric door strike, providing seamless access.
The switch connects via two wires to the electric door strike, and if you already have an intercom system installed, these wires can be connected at the same point for even easier integration.
Custom Lock Solutions
We offer custom-made door panels that are designed to accommodate the USPS arrow key lock. These panels can be tailored to your specific needs and building configuration.
Our custom-made solutions are designed to be versatile, allowing you to choose the features that matter most to you. For example, you can opt for custom-made door panels that fit your building's unique configuration.

Key Management
The United States Postal Service requires a specific lockbox for mail carriers to access building keys, known as a USPS key keeper box.
These lockboxes are designed for USPS use and are government-owned, so they can't be purchased by developers or property owners. To obtain one, contact your local post office or speak directly with your mail carrier.
The mail carrier uses a USPS arrow key to open the lockbox, retrieves the building key, unlocks the door, and then returns the key to the lockbox after delivering the mail.
Alternatively, the lockbox can be equipped with a button that, when pressed by the mail carrier, activates the electric door strike, granting access without handling a physical key.
US Mail Supply carries USPS-approved key keepers that can be used to give mail carriers secure access to the key of a locked building, and they also come in surface mount and recess mount options.
Private Lock Conversion
Private Lock Conversion is a viable option for those who need to secure their USPS mail lock. Conversion locks are available that match the mechanism and dimensions of USPS arrow locks, but are keyed for private use.
If you're looking to convert your USPS mail lock to a private lock, you'll want to find a conversion lock that fits your needs. Conversion locks are designed to be compatible with USPS arrow locks, so you can easily swap them out.
Having a private lock conversion can provide an added layer of security for your mail and packages. This is especially important if you live in a shared space or have sensitive information being sent to you.
USPS arrow locks are a common type of lock used for mailboxes, and conversion locks are available to match them.
