Rules worth knowing

In Ontario, every commercial motor vehicle must show the owner's name on both sides (Highway Traffic Act s.103(1)). This kit gives you the letters to do it yourself; you choose the wording, height and spacing. Want it laid out for you? Order the made-for-you lettering instead.

Questions

What exactly is in this pack?

Two letter sets spelling CVOR, USDOT and NSC, plus twelve of every digit 0 to 9 (eight for the two door numbers, four more for fleet unit numbers) (24 prefix letters and 120 digits, 144 characters total).

Will my number fit on both doors?

Yes for 99 of every 100 nine-digit CVOR numbers and nearly every seven-digit USDOT number, on both doors. A number only fails if one digit appears five or more times. Type your number into the fit check on this page before you order.

Which prefix letters do I get?

Two complete sets of CVOR, USDOT and NSC. Across the pack that is four each of C, O and S, and two each of D, N, R, T, U and V. Choose the prefix you need; these are individual letters, not three joined labels.

How many of each number are included?

Twelve of every digit 0 to 9. Both doors use each digit twice, so a digit can appear up to 6 times in your number. The extra four of each are for fleet unit numbers.

Do I need CVOR, USDOT or NSC markings?

Use only the prefix and number that apply to your operation. These letters do not establish a requirement, issue a carrier number or replace other vehicle markings. Confirm your wording, size, contrast and placement for the places where you operate.

Are 2 inch or 3 inch letters a legal minimum?

These are offered print sizes, not a statement of a legal minimum. Measure your door space and confirm the rules that apply before choosing.

Can I add my business name?

This pack only has the stated prefix letters and digits. A full business name needs an alphabet kit or custom door lettering. It does not contain every letter of the alphabet.

How do I choose the size and spacing?

Height means the capital-letter or digit height, not the width of a whole line. Width varies by character and style. Lay out every character on its backing and measure the full line with your chosen gaps before peeling. Leave room for door handles, seams and edges. The kit has no fixed spacing.

What is included for fitting it?

Loose, weeded characters on backing sheets. Transfer tape, a squeegee, cleaner and masking tape are not included. Arrange the characters yourself; this is not an already spaced line.

How do I apply the characters straight?

Start with a clean, smooth, dry surface. Check that your cleaner is safe for the finish and let it dry fully. Use removable masking tape as a guide, lay out the full line first, then apply each character and press it down firmly. Lift the guide carefully.

Can I apply these in cold weather?

Apply when the surface, vinyl and air are above 10 degrees Celsius. Bring the job into a warm, dry space and allow it to warm through. Do not apply over frost, moisture, wax or grease. Follow the supplied material instructions if they require warmer conditions.

Will these stick to textured plastic or damaged paint?

These are for smooth painted metal, aluminium, glass, fibreglass and suitable smooth rigid plastic. Textured plastic, flexible covers, chalky surfaces, flaking paint, rivets and deep seams need a different solution. Check a small area before fitting the full line.

Can I remove them or move them later?

Treat each character as a one-use decal. For removal, use gentle warmth and peel slowly. Test any adhesive remover in a hidden area first. Old paint may lift and sun-exposed surfaces may show an outline. Clean removal without marks is not promised.

Can I mix sizes, colours or styles in one kit?

One kit uses one selected style, height and finish throughout. For a mix, order separate kits. The letters are capitals; punctuation, accents and logos are not included.

What if I need more of one character?

Count each character across every side you will mark before ordering. A fixed kit cannot substitute one character for another. Order another kit or choose the custom, already spaced option if the count does not cover your wording.

Is registration or approval included?

You supply your own valid numbers and wording. Buying lettering does not register a boat or vehicle, issue a number, or approve its markings. Check the rules for your vehicle and where it operates.

What does shipping cost?

The listed kit price includes tracked delivery in Canada, so a kit alone ships free. Add a kit to any other order and the kit is $7 off at checkout, since it ships in the same box. United States kit shipping is $7.99. Taxes are shown at checkout.

Will it show up at night?

Gloss and matte finishes are not reflective. Choose the separate reflective kit for a finish that returns light towards headlights. Keep a strong contrast with the surface in daylight too.
