120 PCS Reflective Mailbox Numbers And Letters (2 Inches)

Best for compact spaces and small mailboxes. This set includes 120 pieces—60 numbers (0-9) and 60 letters (A-Z)—distributed across 12 sheets. The material is PET, offering waterproof and weatherproof properties for outdoor use. The reflective finish enhances visibility when light hits the surface, aiding night-time identification of your address or mailbox number. Suitable for mailboxes, bins, windows, doors, and small address plates. Caution: The 2-inch size may be too small for long addresses on larger homes; ensure your address format fits within the space.
132 Pcs 2″ Reflective Letters & Numbers (White Vinyl)

Best for comprehensive address labeling with plentiful characters. The package contains 132 pieces: five sets of 2″ number stickers (0-9) and 26 letters (A-Z), plus sunflowers for decoration. The vinyl is weatherproof, UV resistant, and designed for outdoor and indoor use, with strong adhesion. Reflection depends on light brightness, making it reliable in low-light conditions. This option is ideal for those who want a full alphabet and numbers kit in one order. Caution: Letters may require careful alignment to ensure readability from a distance.
Hillman 3″ Black And Silver Reflective Letters

Best for high-visibility on larger mailboxes or home signs. The Hillman set offers 3-inch reflective letters in black and silver, designed to be weather-resistant. The adhesive works best on dry, smooth surfaces such as mailboxes or walls. Choose this if you need larger characters to catch attention from the street, especially on bigger properties. Limitation: The set notes general usage, but it does not specify the total number of letters included, so plan for potential gaps if your address requires many characters.
100 Piece Reflective Mailbox Numbers (2″)

Best for steady, long-term outdoor labeling with clear nighttime visibility. This set includes 100 decals—40 numbers (0-9) and 60 letters (A-Z)—in reflective vinyl. The material is waterproof, weatherproof, and UV resistant, designed to endure outdoor conditions. It is suitable for mailboxes, doors, windows, cars, and signs. Caution: While reflective, adhesion strength on very rough surfaces may vary; ensure a clean, smooth installation surface for best results.
120 PCS Reflective Letters And Numbers (3″)

Best for standout readability on larger addresses or signs. The set includes 120 pieces across 12 sheets, with 60 numbers (0-9) and 60 letters (A-Z) in a 3-inch size. PET material provides waterproof and weatherproof performance, with reflective properties to improve visibility under light. This option is well-suited for homeowners who want bold characters for easy identification from the street. Caution: The larger size may overwhelm small mailbox fronts; verify space before installation.
Buying Guide: Key Considerations For Reflective Mailbox Letters
- Size and space: Choose 2″ for compact mailboxes or 3″ for larger signs and street readability. Measure your installation area before buying.
- Material: PET and vinyl options offer waterproof and weatherproof performance. Consider UV resistance for prolonged outdoor use.
- Quantity and alphabet coverage: Ensure the set provides enough numbers and letters for your address format; complete sets simplify installation.
- Adhesion: Look for strong, weatherproof adhesive and a clean, dry surface for best results. Rough or dusty surfaces may reduce stickiness.
- Reflectivity: The effectiveness depends on ambient lighting. Higher contrast colors (black/silver, white vinyl) generally improve visibility.
- Ease of installation: Pre-spaced or self-adhesive sheets simplify alignment, but you may still need a ruler or stencil for neat spacing.
