What the AI looks for in Mailbox Numbers
- Character height
- USPS guidance calls for numbers at least 1 inch high; go larger for curbside visibility Carriers and emergency responders need to read it from the road.
- Placement
- On the side of the box visible to the carrier's approach, or on the box door; on both sides if the post serves traffic from both directions Numbers facing away from traffic are useless.
- Reflectivity and contrast
- Reflective or high-contrast digits against the box color Emergency crews need to find the address at night.
- Adhesive and surface
- Outdoor-rated vinyl applied to clean, smooth, dry metal or plastic above roughly mild temperatures Most stick-on failures come from cold or dirty application.
Brands that matter
