Sign Specifications and Customization Options

Our mailbox signs are made to last and are designed for maximum visibility. The standard size for mailbox signs is 6″ x 18″, and the sign blanks are constructed from .063 gauge aluminum, making them durable, rust-resistant, and sturdy enough to withstand the elements without easily bending. Both the background and numbers are made from high-quality reflective vinyl (not paint), ensuring long-lasting visibility even in low-light conditions.

Mailbox Sign Features
  • Size: 6″ x 18″
  • Material: .063 gauge aluminum (rust-resistant and durable)
  • Reflective vinyl for both background and numbers
  • Color Options: Available in all standard traffic colors including red, brown, green, blue, yellow, orange, and white
  • Number Size: Choose from 3″ or 4″ numbers (3″ is most commonly used)
  • Orientation: Numbers can be applied vertically or horizontally, with both sides of the sign typically featuring numbers for increased visibility.

The standard size for house signs is 5″ x 14″. These signs are single-sided, meaning the background and numbers will be applied only to one side of the sign. The material and customization options for house signs are the same as our mailbox signs, and they are ideal for homes located less than 50 feet from the roadway.

We offer a variety of color combinations to suit your needs:

  • White numbers on green, blue, red, or brown background
  • Green, blue, red, or brown numbers on white or yellow background
  • Yellow numbers on green, blue, red, or brown background

Whether you’re looking for a mailbox sign or a house sign, we ensure that every sign is built for visibility and durability, providing clear identification for homes and properties.
