Custom Aircraft Registration N Number Decals

Our N number decals are precision-cut to FAA-compliant proportions per 14 CFR Part 45 — including correct character height, width, stroke width, and spacing ratios.

We use FAA-approved lettering styles, as Part 45 restricts N number fonts to specific roman capital letter forms; decorative, script, or stylized fonts are not permitted.

We also do our best to look up your N number in the FAA registry before production as a courtesy check, though many customers are ordering for a freshly registered aircraft that may not yet appear in the registry.

Ultimately, it is the pilot-in-command's responsibility under 14 CFR § 45.29 to ensure their aircraft displays marks of the correct size for their specific aircraft category, airworthiness certificate type, and operating area.

If you are unsure what size your aircraft requires, please review our sizing FAQ below or consult your local FSDO before ordering.

The correct N number size is set by 14 CFR § 45.29 and depends on your aircraft category.

Here is a breakdown by aircraft type:

Standard category fixed-wing aircraft (Cessna 172, Piper Cherokee, Beechcraft Bonanza, Cirrus SR22, etc.): minimum 12 inches required.

Rotorcraft and helicopters (Robinson R22, R44, Bell 206, etc.): minimum 12 inches required.

Experimental amateur-built (EAB), experimental exhibition, and kit-built or former light-sport aircraft with a maximum cruise speed at or below 180 knots CAS: minimum 3 inches allowed under § 45.29(b)(1)(iii).

Powered parachutes, weight-shift-control aircraft (trikes), airships, and balloons: minimum 3 inches required under § 45.29(b)(2).

Antique aircraft built at least 30 years ago, and experimental exhibition aircraft sharing the same external configuration as an aircraft built at least 30 years ago: may qualify for marks as small as 2 inches under § 45.22.

Any aircraft crossing an ADIZ or DEWIZ: temporary or permanent 12-inch N numbers required under § 45.29(h), regardless of category.

The FAA sets minimums only — not maximums. Many owners choose larger sizes (14, 16, 18, or 20 inch) for better visibility or to proportionally fill a larger fuselage or tail surface. We offer sizes from 2 inches through 20 inches to cover every aircraft type and airframe.

Enter your full FAA registration number exactly as it appears on your aircraft registration certificate — for example, N12345 or N123AB. Always include the leading 'N'. Your N number can contain 2–6 alphanumeric characters following the N. If you are unsure of your registration number, you can look it up on the FAA Aircraft Registry at registry.faa.gov.

Per FAA regulations, N number markings must appear on the fuselage or vertical tail surface and must be visible from both sides of the aircraft. That's why our set includes two matching decals — one for each required location. The markings must contrast with the background color of your aircraft and be applied to a smooth, unobstructed area of the airframe

Our airplane registration decals are made from Oracal 751, a premium aviation-grade cast vinyl engineered for outdoor durability. It is UV-resistant, non-shrinking, and rated for 5–7 years of outdoor exposure. The vinyl adheres securely to aluminum, composite, fiberglass, and painted aircraft surfaces without peeling, fading, or cracking under the stress of flight conditions.

Yes. Our aircraft registration decals are compatible with aluminum, fiberglass, composite, and factory or custom-painted airframe surfaces. The Oracal 751 cast vinyl used in our decals is specifically formulated for high-performance adhesion to aircraft surfaces. For best results, clean the surface with isopropyl alcohol before application.

Each N number decal set arrives pre-spaced on a single transfer tape sheet for easy, bubble-free application — no special tools required. Simply clean the surface, peel the backing, position the decal, and squeegee it into place. Then slowly peel away the transfer tape. The entire application process takes just a few minutes per decal.

Yes. We offer N number decals in a wide range of colors so you can choose the option that best contrasts with your aircraft's fuselage or tail color — a requirement under FAA regulations. Common choices include black, white, red, blue, and chrome. Custom colors are also available by request. Contact us through our Request a Quote page for custom color matching.

When properly applied to a clean aircraft surface, our N number decals are rated to last 5–7 years outdoors. The Oracal 751 aviation-grade vinyl is UV-resistant and designed to withstand the temperature extremes, vibration, and weather exposure typical of regular aircraft operation. Hangared aircraft may see an even longer lifespan.
