Check before you buy

Digit height. The International Fire Code, which many US jurisdictions adopt, requires residential address numbers at least 4 in high with a stroke width of at least 0.5 in. Check your local code, which may require more. Emergency responders need to read the address from the street, and undersized digits can fail inspection.
Contrast with the background. Numbers must contrast with the surface they are mounted on, such as dark on light or light on dark. Contrast matters more than finish for legibility at night and from a distance.
Material and finish. Prefer solid stainless steel, cast or solid aluminum, or lacquered brass. Be wary of plated zinc for coastal or harsh climates. Plated and painted cheap metals pit and peel outdoors, and unlacquered brass darkens.
Mounting hardware. Confirm the included anchors suit your wall (masonry, wood, vinyl or stucco), and look for a drilling template with floating standoffs. Crooked or mismatched spacing is the most common install failure.

Individual numbers or a plaque?

Choose individual numbers when you want to match a modern facade or space digits freely. Choose a plaque for one-piece mounting, a lawn or mailbox placement, or a personalized street name.
