Learn More About Custom Letterboxes

A custom letterbox is not only a mailbox body. For many projects, buyers also need the correct size, mounting style, front panel, house number, sign plate, lock, color, and packaging.

We support custom letterbox boxes for different property styles, including modern homes, brick walls, apartment entrances, fences, and commercial buildings. If your project requires a custom made letterbox with matching faceplates, engraved signs, or stainless steel details, we can help review the design before production.

Project Example

Custom Letterbox Faceplates for a Residential Building Project

A property contractor needed a batch of custom letterbox faceplates for a multi-unit residential entrance. The main concern was that the faceplates had to match the wall opening, keep the numbers clear, and maintain a consistent finish across all units.

We reviewed the drawing, adjusted the mounting holes, confirmed the number position, and produced samples before bulk production. The final order used powder-coated metal faceplates with custom numbers and matching lock openings, helping the contractor reduce installation issues on site.
