4 inch reflective mailbox numbers white — 4 sets (40 pieces)
Package includes four sets of 4-inch reflective vinyl numbers (0–9 in each set).

Product Overview

These reflective mailbox numbers are supplied as four sets of 4-inch white vinyl digits — each set contains the digits 0–9, so you receive 40 pieces total. The numbers are made from premium reflective vinyl that bounces light back to its source, improving nighttime visibility and helping carriers locate your address quickly.

Reflective Effect

The numbers are manufactured from reflective vinyl that shines when hit by headlights or flashlights, making your mailbox easier to find in low-light conditions and reducing missed or misplaced deliveries.

Weather & UV Resistant

Designed for outdoor use, the stickers resist sun, rain, wind, snow and temperature changes so they stay readable and intact season after season.

Strong Self-Adhesive

Each number has a strong adhesive backing. Install in three easy steps: clean the surface, peel the backing, press in place — and you’re done.

Versatile Use

Use them on mailboxes, doors, garbage bins, trucks, billboards or any surface where clear, reflective numbering helps visitors or delivery drivers.

Why pick reflective vinyl numbers?

Reflective numbers are a small, inexpensive upgrade that significantly improves visibility and reduces delivery errors — especially at night or in poor weather. Because this pack contains extra digits, you can put numbers on both sides of a mailbox, or keep spares if you need repeating digits (e.g., “11” or “122”).

Installation Tips

  1. Clean the surface with a damp cloth to remove dirt, grease and dust.
  2. Dry thoroughly — adhesive performs best on clean, dry surfaces.
  3. Peel off the transparent film from the backing, stick the adhesive side to the mailbox, then remove the protective film from the number itself and press firmly for 30 seconds.
  4. For curved or textured surfaces, press and hold longer and allow 24 hours before exposure to heavy rain.

Common Uses

Address numbers for residential mailboxes, house doors, apartment bins, rental properties, workplace signage, fleet vehicles, event signage and temporary construction markers.
