Tracking calls from vehicle ads
Tracking calls from vehicle ads takes four simple methods: a phone number used only on vehicles, a WhatsApp link with a pre-filled message, asking “where did you see us?” on every call, and comparing enquiries before and after branding. Any one of them beats guessing.
The problem: “we can’t measure it”
Vehicle advertising is often treated as unmeasurable, so it gets cut first when budgets tighten. In reality, a branded vehicle carries a direct call to action: a phone number. That number can be tracked.
Four methods, from easiest to most precise
- Ask at call time. One question: “Where did you see our number?” Record the answer in a simple sheet.
- Before and after. Compare monthly enquiries in the three months before branding with the three months after.
- WhatsApp with a set message. A short link or code on the vehicle opening a chat that starts with a fixed phrase, so you know where it came from.
- A dedicated number. A line printed only on vehicles. Every call to it came from the road.
Why lifespan changes the result
Return is enquiries divided by total cost. If stickers burn and peel within 8–12 months, the cost repeats 2–4 times over 5 years. With one installation lasting up to 5 years, the same enquiries come at a total cost that is 53–72% lower.
Clean Master’s 5 vans used to fade every year. Since switching to 3M, they have gone 16 months without fading, so the same installation keeps generating calls without new spending.

Common tracking mistakes
- Using the same number as your website and invoices, then guessing the source.
- Printing the number too small to read from a following car.
- Measuring only for one month.

Frequently asked questions
Does a QR code on a vehicle work?
Only where people can scan it: on parked vehicles or at the rear in slow traffic. A clear phone number is more reliable while moving.
How long should we track before judging results?
At least three months, to smooth out seasonal swings.
