USPS Compliance

The USPS has established some rules about the placement and construction of cluster mailboxes and mailbox canopy installations:

• The location of cluster box units must be approved by the USPS to ensure that these mailboxes can be accessed easily and safely by mail carriers.
• Most cluster mailboxes must be located within one block of the residences or commercial buildings they serve.
• The USPS will supply its own master access lock to ensure access for their mail carriers. This locking system is not available for builders or developers and must be installed and maintained by the USPS.
• Most cluster box units must be located on the right side of the road to allow easy access without requiring mail carriers or customers to break any traffic laws to deliver or to retrieve mail.
