CBU Cluster Mailboxes: What are they and how do I purchase them?
Secure and safe mail delivery is a top priority in apartment buildings, residential developments, and business properties. The CBU cluster mailbox is among the best and most popular solutions. Don’t know what a CBU is, how it works, or where to buy a good one? This guide will walk you through the fundamentals—and recommend a trusted source: GoMailboxes.
What is a CBU Cluster Mailbox?
CBU is an acronym for Cluster Box Unit—a compact, secure mailbox system for distributing mail to several recipients in one location. Rather than individual mailboxes at each door, a CBU concentrates several locked compartments into a single, weather-resistant, heavy-duty unit.
They are usually working in:
Residential subdivisions
Gated communities
Flat dwelling
Shopping centers
The United States Postal Service (USPS) strongly recommends CBUs due to their efficiency in mail transport, added security, and savings.
Major Features of CBU Cluster Mailboxes
Long-Lasting Construction: CBUs are made of heavy-gauge aluminum or steel that can withstand harsh weather and vandalism.
Secure Mail Access: Each compartment has a USPS-authorized lock, which keeps mail secure from tampering or theft.
Parcel Lockers: Some models have one or more of the large lockers employed to receive packages securely—especially useful with the rise of online shopping.
Outgoing Mail Slots: Individuals can simply send their mail via outgoing slots.
USPS Compliance: The CBUs are built to USPS specifications for size, height, and installation and approval ease.
Why Install a CBU Cluster Mailbox?
- Advanced Mail Security
Regular mailboxes are vulnerable to theft or destruction. CBUs offer locked, tamper-evident containers for secure delivery.
- Delivery Efficiency
Cluster mailboxes reduce the number of stops mail carriers have to make, speeding up service for everyone.
- Lower Costs
For developers and property managers, a centralized CBU system is less expensive and simpler to maintain than a hundred individual mailboxes.
- Neat, clean appearance
One strategically located piece creates a tidy, uniform appearance, enhancing the look of the property.
- Made for Packages
With parcel lockers integrated, CBUs meet the increasing demand for package delivery security—stopping missed deliveries and porch piracy.
