What goes on a car for sale sign

A car for sale sign needs your phone number, the asking price, and the car's year, make, and model. That is the minimum. Buyers driving past should be able to read all three pieces of information from ten feet away, which means large, dark lettering on a light background. The sign should be visible from both directions if the car sits on a street, and positioned so it does not block the windshield or windows — a buyer cannot decide to stop if they cannot see inside the car.

Beyond the basics, you can add the mileage, transmission type (automatic or manual), and a brief note about condition ("runs great," "new tires," "needs work"). Keep the text short. A sign crowded with details becomes hard to read at speed, and the most important information — that the car is for sale and how to reach you — gets lost.

Do not include your full name or home address on the sign. Your phone number is enough. This protects your privacy and reduces the risk of someone showing up at your house at an unsafe time.

Key Takeaways

  • A car for sale sign must display your phone number, asking price, and the car's year, make, and model in letters large enough to read from ten feet away.
  • Use dark lettering on a light background (or light lettering on dark) so the sign is readable in daylight and does not glare.
  • Position the sign on the car's side or back window so it does not block the view into the vehicle, which is what attracts buyers to stop.
  • Keep text minimal and avoid including your home address or full name — your phone number is sufficient contact information.
  • find the sign firmly so wind or passing traffic does not knock it loose or damage the car's paint.

Materials and sizing for readability

The easiest option is a pre-made cardboard sign from an office supply store or online retailer. These come in standard sizes (usually 11 by 14 inches or 18 by 24 inches) and have space for you to write in your details with a marker. The 18 by 24 inch size is better for street visibility. If you are selling a truck or SUV, the larger size is worth the small cost.

For lettering, use a thick permanent marker in black or dark blue on white or yellow cardstock. Avoid thin markers or ballpoint pens — they are hard to read from a distance. If you have access to a printer, you can also print text in a large font (36 points or larger for the phone number and price) and tape it to a blank cardboard sign. This looks more professional and is easier to read than handwriting.

Do not use poster board alone without lamination or plastic covering. Rain and sun will fade the ink within days, and the sign will look neglected. If you are printing your own, cover it with clear packing tape or a plastic sheet to extend its life.

Where and how to attach the sign to your car

The back window is the most common and effective location. Use suction cups (the kind designed for signs) or painter's tape to hold the sign in place. Suction cups work best on glass and are reusable. Painter's tape is gentler on paint than masking tape and leaves no residue, but it can peel off in wind or heat. Test your attachment method before you leave the car unattended — a sign that falls off looks unprofessional and may damage the car or someone else's property.

If you are parking on a street, angle the sign so it faces the direction traffic flows. If the car is visible from both directions, use two smaller signs, one for each side. Never attach a sign to the windshield or front window — it blocks the view into the car, which is the first thing a potential buyer looks at.

Check the sign daily. Wind, sun, and rain can loosen it or fade the text. If it looks damaged or hard to read, replace it. A worn sign signals that the car has been sitting for a long time and may discourage interest.

What information to include and what to leave out

Required: phone number, price, year, make, model. Optional but helpful: mileage, transmission, fuel type, and one or two words about condition. Examples: "2015 Honda Civic, 85k miles, automatic, runs great, $9,500, call 555-0147" or "2008 Ford F-150, manual, needs work, $3,200, 555-0147."

Do not list mechanical problems in detail on the sign. If the engine needs work or the transmission slips, mention it briefly ("needs work") or leave it out and explain when someone calls. A sign that reads like a repair list will scare off buyers before they even call. Similarly, do not list every upgrade or feature — that is what the conversation is for.

Avoid cutesy language or jokes. "Barely driven by a little old lady" or "Runs like a dream" can come across as dishonest, even if true. Stick to facts. Buyers respect straightforward information and are more likely to call if they trust what they are reading.

Protecting your privacy and safety

Your phone number is the only personal information a buyer needs. Do not include your name, address, email, or social media handles. This keeps your home and identity private and reduces unwanted contact.

When someone calls, you control where and when the showing happens. Meet during daylight hours in a public place if possible — a busy parking lot or street is safer than your home. If you do show the car at home, let a friend or family member know you are expecting someone, and consider having them present during the showing.

Be cautious of buyers who ask for your address before calling or who pressure you to show the car at an odd hour. These are red flags. You are in control of the process, and it is fine to decline a showing that does not feel safe.

Updating or removing the sign when the car sells

Once you have sold the car, remove the sign when ready. A sign left on a sold car confuses potential buyers and makes it look like you are not paying attention to the sale. If you are selling multiple cars, make sure each sign matches the correct vehicle — a mismatched sign damages your credibility.

If the car does not sell after a few weeks, refresh the sign. Fade, dirt, or a worn appearance can make a car look less desirable. A clean, readable sign signals that you are actively selling and taking care of the vehicle.

Keep the sign materials for your next sale. A good cardboard sign and markers can be reused, which saves money and time.

Frequently Asked Questions

Can I use a digital sign or QR code instead of a paper sign?

A QR code can work as a supplement to a paper sign, but not as a replacement. Many people driving past will not have time to scan a code, and not all phones will read it reliably. A paper sign with your phone number is faster and more direct. If you want to use a QR code, print it on the sign alongside your phone number so buyers have both options.

What size letters do I need for the price and phone number?

The price and phone number should be at least 2 inches tall so they are readable from 10 to 15 feet away. The year, make, and model can be slightly smaller (1 to 1.5 inches) but should still be straightforward to read from a moving car. Test your sign by standing across the street and checking if you can read it clearly.

Should I include the VIN or license plate number on the sign?

No. Your phone number is enough for interested buyers to reach you. The VIN and license plate are details you can share during a call or showing. Posting them publicly increases the risk of identity theft or fraud.

Is it legal to park a car with a for-sale sign on my street?

Laws vary by city and neighborhood. Some areas allow it indefinitely, while others limit how long a car can sit with a for-sale sign. Check your local parking rules or contact your city's parking department before you post the sign. Some neighborhoods also have HOA rules about for-sale signs, so review your community guidelines if you live in one.

How long should I leave the sign up if the car is not selling?

There is no set time limit, but if the car has not sold after three to four weeks, consider lowering the price or refreshing your marketing approach. A car that sits with a sign for months can start to look like it has problems. If local rules limit how long a for-sale sign can stay up, follow those guidelines and explore other selling methods once the time expires.
