Mailboxes

Mailboxes for Residential and Commercial Use

Mailboxes are exterior and building-mounted mail products associated with homes, offices, apartments, shared entries, and commercial properties.

The category may include wall-mounted mailboxes, post-mounted mailboxes, multi-unit mailbox systems, mailbox doors, locks, posts, numbers, and replacement parts.

Product grouping is based on mailbox format, installation location, capacity, access style, material family, and architectural appearance.

Mailbox systems vary widely by the property they serve. Residential customers often need a roadside mailbox, a post-mounted unit or a compatible support post. Apartment buildings, mixed-use properties and business complexes may instead require centralized mail delivery products that provide multiple individual compartments. Start by selecting the format and access arrangement rather than comparing products solely by finish or appearance.

USPS horizontal mailboxes can include 4C and other qualifying horizontal mailbox formats, while cluster mailbox units are commonly used for grouped delivery locations. Vertical mailboxes serve a different mounting format and should be compared by mailbox-door quantity and access configuration. Always verify the exact model and any applicable postal requirements with the serving postal authority; a manufacturer description does not replace local installation approval.

Private-delivery mailboxes are another distinct category. They may be appropriate where distribution is performed by an organization or another authorized operator rather than directly through a USPS-controlled access arrangement. Match the chosen system to how mail will actually be delivered, who will open master-access compartments and what mounting or enclosure components are included. A freestanding enclosure, a replacement pedestal, or a replacement door alone is not a complete mailbox system.

For exterior and residential projects, explore residential mailboxes and posts and residential mailbox posts. When repairing an installed unit, use mailbox parts and identify the original manufacturer, model and door size before selecting a replacement. This category structure helps keep complete mailboxes, mounting hardware and repair components easy to distinguish while supporting accurate product selection.

When planning a new installation, compare the full components list before calculating the order. A freestanding system may require a different base or pedestal from a wall-mounted assembly, and the presence of a parcel locker door in a product name does not mean the product includes a complete locker unit. For an existing mailroom, the replacement part number should be cross-checked against the installed manufacturer's series and door dimensions. Customers shopping several locations can organize selections by property, delivery access, finish and required quantities to avoid ordering mismatched sets of boxes and supports.
