Securely marked – anonymously protected
Whether it’s a laptop, tablet, smartphone or work device – with BackCode, you can protect your tech from permanent loss.
A unique code makes it easy for finders to contact you anonymously, without revealing personal details such as your name or address.
This increases your chances of getting your valuable devices back safely and quickly – without the need for GPS tracking, an app or a battery.
How it works
Simple, secure and free: create your BackCode online, print it out or attach it yourself – for example, to your key ring, school bag or bike. You don’t need to buy anything to use BackCode – but by purchasing our tags, stickers or cards from the shop, you’ll be supporting the project and helping to expand it further.

The message goes straight to you
Security through anonymity
Your devices are clearly marked, but your privacy remains protected.
Finders see only the code – no contact details – and can send you an anonymous message via backcode.de.
This ensures that returns are handled in a trustworthy and privacy-friendly manner.
Ideal for everyday life & work
Whether at the office, at school or on the go – devices are easily forgotten or lost.
With a BackCode on your device, you can stay reachable without revealing any sensitive data.
This ensures security for you, your family and your business.
Durable & maintenance-free
Once fitted, your BackCode works indefinitely – without electricity, a battery or an app.
It is robust, water-resistant and remains reliably legible even with daily use.
This allows you to protect your devices with minimal effort and maximum effectiveness.
No technology or subscription required
BackCode always works – without a battery, Bluetooth or monthly fees.
The code is permanently active, weatherproof and device-independent. This means everything remains securely marked, even if the technology fails.
Advantage over trackers and conventional tags
Traditional key rings often display a name or address – which isn’t secure.
Trackers such as AirTags may show where the key is, but finders cannot contact you using them.
BackCode is different:
The finder can send you an anonymous message without you having to disclose any personal details.
This gives you the best chance of getting lost items back safely and easily – without any technology, battery or subscription.
