Brass Mailbox & House Numbers

Brass mailbox numbers upgrade curb appeal with a polished, high-contrast address display that holds up through years of sun, rain, and temperature swings. Solid brass screw-mount numbers are made for permanent installs, while self-adhesive numbers are great for quick upgrades. Both options are available in 2 inch brass mailbox numbers and 3 inch brass mailbox numbers to fit a range of mailbox sizes and viewing distances.

Vinyl numbers fade, crack, and peel within a few seasons. Aluminum numbers hold their shape but lack the visual weight buyers notice at the curb. Brass delivers a finish that reads as intentional, not afterthought.

Size selection depends on four factors: viewing distance, mailbox dimensions, digit count, and whether you are mounting directly to the mailbox face or onto a number plate. The table below covers the most common scenarios.

Buyers with HOA requirements or local ordinance restrictions should check their guidelines before selecting a size, as minimum height rules vary by municipality.

Peel-and-stick brass numbers remove the need for a drill and cut install time to under five minutes. The bond holds reliably on clean, smooth, dry surfaces: painted metal, flat plastic, and powder-coated finishes all take the adhesive well. Three surface conditions affect long-term adhesion:

O   Texture: Rough or heavily textured mailbox surfaces reduce contact area and weaken the bond over time.

O   Curvature: Tight curves on rounded mailbox bodies prevent full contact across the number face, which shortens adhesion life.

O   Exposure: Direct sun and high humidity accelerate adhesive breakdown on any peel-and-stick number, brass or otherwise.

Self adhesive brass mailbox numbers are not designed to reposition. Press firmly and place accurately on the first attempt.

Screw-mount and adhesive brass numbers both install in minutes. Follow these steps for a clean, aligned result:

O   Clean the surface first: Wipe the mounting area with isopropyl alcohol and let it dry fully before touching the number to the mailbox.

O   Wear gloves: Skin oils transfer to brass and leave marks that show under direct light. Handle numbers by the edges.

O    Dry-fit before committing: Hold each number in place and step back to check alignment before drilling or peeling the backing.

O   Work in moderate temperatures: Most adhesive bonds work well between 50°F and 90°F. Cold surfaces reduce
      initial tack; hot surfaces accelerate cure but shorten repositioning time to near zero.

O   Space multi-digit addresses evenly: Use a ruler or spacing template to set consistent gaps before marking drill
      points or pressing adhesive numbers down.

O    For screw-mount installs: Use the included hardware where provided. Stainless or brass screws prevent rust bleed onto the mailbox face.
