The digital note behind your windshield wiper.
A QR sticker for your car. Whoever you block in scans it and calls you, messages you, or sends you a note through our Telegram bot. Your phone number is never printed on the car.
Free, no app, ready in a minute. The code is on GitHub
Everyone has been blocked in.
No note on the dashboard and no idea where the driver went. You honk, you wait, and sooner or later someone calls the tow truck. Parkzettel gives the driver a way to be reached, without writing a phone number on the windshield.
How it works
Create
Enter your plate and how you want to be reached: call, WhatsApp, Telegram, or messages through our bot.
Print
Print the sticker at 8 cm and put it inside the windshield, facing out.
Get reached
Whoever you block in scans it with their phone camera and gets in touch. No app needed on either side.
Two kinds of sticker
Private sticker
- Nothing is stored and no account is needed.
- People call or message you directly, so they see your number.
- Changing your details means printing a new sticker.
Relay sticker
- Your number stays hidden: messages reach you through our Telegram bot, and you answer with one tap.
- Edit or switch off the sticker any time without reprinting. The QR code is smaller and easier to scan.
- Needs Telegram and a login. We store your Telegram ID, the plate and the note.
Private by design
- Your phone number is never printed on the car.
- Private stickers store nothing anywhere: your details are encrypted into the QR code itself.
- Relay stickers hide your number completely, and you can switch them off at any time.
- No ads, no tracking cookies, no app to install.
Speaks the scanner's language
The page someone sees after scanning your sticker appears in their phone's language:
- Deutsch
- English
- Italiano
- Français
- Español
- Nederlands
- Polski
- Türkçe
- Українська

Questions
Does it cost anything?
No. Parkzettel is free, and its code is public on GitHub.
Does the person who scans it need an app?
No. Any phone camera opens the page.
Can strangers see my phone number?
With a private sticker, people who scan it see the contact options you chose. With a relay sticker, nobody sees your number: messages reach you through Telegram.
What if my number changes or I sell the car?
Relay stickers can be edited or switched off online, and the printed sticker follows. A private sticker cannot be changed: remove it and print a new one.
