Blocked in? Lights left on? A window open in the rain? Scan the CarTag badge on the windscreen or search the plate, and the owner gets your message in seconds. Neither of you sees the other's phone number.
On a computer? Point your phone's camera at the code in the picture to get CarTag on your phone.
Scan with your camera
At someone's car?
No more notes under the wiper or waiting next to the car.
Point your phone's camera at the CarTag badge on the windscreen. No badge? Type the plate or photograph it in the app.
A one-time code by WhatsApp or SMS shows you are a real person. The owner never sees your full number.
Pick a reason and send a message, or call the owner through the app. The owner hears from you straight away and answers in the same conversation.
Features
Create your badge in the app, print it at postcard size and place it inside the windscreen. Anyone with a phone camera can scan it, and no app is needed to read your message.
Type the plate or point the camera at it. The plate is read on the phone and the photo is deleted straight away. Without an account you only learn whether the car is on CarTag.
Pick one of the ready-made reasons and add a note of up to 300 characters. Your number stays hidden, and nothing else changes hands.
Owners get a notification in their own language, and every contact becomes a conversation: the reason, the message, the answer and every call in one place.
Privacy by design
CarTag was built so that strangers can reach you about your car without learning who you are or how to call you.
Only people who verified a phone number can send a message or call.
Each person can send only a few requests an hour, so nobody can flood you.
A blocked person gets no sign that they were blocked.
Our security records keep only part of each phone number.
Your rules
Talk to the owner through the app. The call is encrypted between the two phones and neither of you sees the other's number.
Selling the car or leaving it at the garage? Stop new requests with one switch. The badge keeps working.
Blocked people cannot reach you again and are not told. Reports go to a moderator.
Your phone number is never public. You decide whether verified people see your WhatsApp number.
A Turkish car parked in Riyadh? Search the plate under its own country.
The app, the badge page and the notifications speak English, Turkish and Arabic.
Download everything we hold about you, or delete your account in the app or on this website.
Own a car?
Set it up once and the badge keeps working for as long as it sits behind your windscreen.
Sign in with a mobile number from any of these countries. Plates from all seven can be searched.
No. The owner sees the reason, your message and your display name if you allow it. Your number is shared only if you choose to share it when you send.
Not to look: your phone's camera opens the owner's page. To send a message you need the app and a verified phone number, which is what keeps owners safe from anonymous abuse.
Yes. The app and the badge are free. All you need is a printer, or a print shop, for the badge.
Block them from your inbox, report them, or replace your badge in the app. The old code stops working immediately.
