Numbering and nameplates

Elke bewoner vindt meteen de juiste bus

In a building with multiple residential units, clear numbering is essential. ONZO provides numbered mailboxes and nameplates, neatly integrated into the system and matched to the look of the building.

Numbering that matches the building

Each mailbox is assigned its own number that corresponds to the residential unit. This allows the postal worker to deliver without errors and helps residents and visitors find the right box immediately. The numbering is executed in a clean and legible way, in keeping with the system.

Nameplates and engravings

In addition to the number, the resident's name can be displayed. ONZO handles this with care, using engravings or nameplates that fit seamlessly into the overall design. When a resident changes, the system continues to look neat.

Aligned with the finish

Numbering and nameplates are matched to the colour and finish of the system, with a choice of more than 2000 RAL colours. View the systems or start the project scan.
