How BackCode works

Simple, secure and anonymous: from loss to return.

Lost → Found → Returned
  1. 1

    Lost & Found

    An item is lost and found by an honest person.

  2. 2

    Scan or enter the code

    The Finder scans the QR code or enters the short code on backcode.de.

  3. 3

    Send an anonymous message & arrange the return

    The finder and the owner communicate anonymously and arrange the return.

Secure & anonymous: All communication takes place via BackCode. Personal contact details remain protected.

BackCode – greater security for lost items

Lost your keys? Left your rucksack behind? Lost your mobile?


With BackCode, you can get your belongings back quickly and easily.

Every BackCode is a unique QR code with a personalised code.

Anyone who finds your belongings can simply enter or scan the code at backcode.de and send you a message directly and anonymously – without you having to disclose any personal details.

Small code – big impact


Simple & quick: Just a scan or a short numeric code is all it takes – and honest finders can contact you straight away.

Secure & discreet: Your personal details remain protected – you decide what’s shared.

Reliable, always: No battery, no app – BackCode works whenever you need it.

For the things that matter to you: Whether it’s keys, a bag, a bike or a laptop – BackCode fits into your everyday life.
