The short answer
Put a dynamic QR code on each vehicle’s window sticker, 5–8 cm (2–3 in) wide for someone standing beside the car, and point it at that vehicle’s page or a test-drive form. Generate codes in bulk from your inventory feed (CSV on the Pro plan, or the REST API on the Business plan), and when a car sells, repoint its code to similar stock.
How to use QR codes on vehicle window stickers
Decide what the sticker opens
A page with photos, specs, price and a “book a test drive” button beats the main inventory page. One page per vehicle, identified by VIN or stock number.
Generate codes from your inventory
For a lot of 100 cars, create codes in a batch from a CSV (Pro). If inventory changes daily, the Business plan’s REST API lets your system create codes automatically.
Print on the window sticker
Add the code to the existing sticker template, at least 5 cm wide with a clear border, dark ink on a white area. Do not print it on tinted glass directly.
Place where a visitor stands
Mount on the inside of the side or rear window at about chest height, not the windshield, which reflects the sky.
Repoint on sale
When a car sells, switch its code to a similar-vehicles page. Late visitors still find something to look at.
Size, distance and placement
- Best code type
- One dynamic URL code per vehicle, named by stock number
- Window sticker
- Read at 0.5–1 m: 5–8 cm (2–3 in) wide on a white area
- Lot sign or banner
- Read from 2–3 m: 20–30 cm
- Placement on the car
- Inside of a side or rear window at chest height; windshield glare is worst
- Creating many codes
- CSV bulk (Pro); REST API for inventory-driven creation (Business)
- Destination
- Vehicle page with photos, specs, price and test-drive booking
- When sold
- Repoint to similar stock
Why dynamic with an inventory feed
A lot’s inventory turns over constantly. Static codes tied to individual vehicle pages die when the page is removed, leaving printed stickers pointing nowhere. Dynamic codes decouple the sticker from the page: you create a code for each vehicle, and when the car leaves the lot you redirect it. With the Business plan API you can create or update codes from your own system as vehicles arrive and sell.
Common mistakes
Tip: name every code with the stock number. Searching the dashboard for a stock number is faster than hunting through dozens of identical-looking names.
Frequently asked questions
How do I create a QR code for each car?
Generate codes from a CSV of stock numbers and vehicle page links on the Pro plan, or create them from your inventory system with the REST API on the Business plan.
How big should the code be on a window sticker?
About 5–8 cm (2–3 in) wide, dark on a white area, for someone scanning from beside the car.
What do I do when the car sells?
Edit the dynamic code’s destination to a similar-vehicles page or your inventory. The sticker keeps working.
Can I use my own domain for the short links?
Yes, on the Business plan: one custom short-link domain per account, so codes show your dealership’s address.
