A useful lost-and-found tag gives the finder a clear next step. With QRChat, scanning the code opens a browser conversation with the owner. The finder needs internet access, but no app or QRChat account. Your phone number is not automatically displayed.

The tag depends on someone finding and scanning it. It is not a GPS tracker, and it cannot guarantee recovery. This guide covers creating the contact route, making the tag readable and testing the whole conversation before you need it.

## 1. Create one code for each item or pet

Open your [QRChat dashboard](/home), or [create an account](/signup). Choose Lost & found and keep Individual chat mode. Give the code a useful name, such as Milo collar or Blue suitcase. Each finder then has a separate conversation with you.

Copies of one pet's code can go on that pet's collar and harness. Give another animal or item a separate code. This makes messages easier to identify and lets you disable one code without affecting the others.

Add a welcome message such as: "Found Milo? Please tell me where you are and whether he is with you." Anyone opening the code can read this message, so leave out your home address and other private information.

## 2. Preserve the QR pattern and its clear border

Download your actual code. Do not copy decorative QR patterns from illustrations. Use dark modules on a light, plain background and keep the code flat and unobstructed.

Leave an empty border at least **four modules wide on every side**. A module is one small square in the QR pattern. This is the quiet zone described by [DENSO WAVE's QR code guidance](https://www.qrcode.com/en/howto/code.html/index.html). Text, attachment holes and decorative frames must stay outside it.

There is no universal tag size that guarantees a scan: the number of modules, finish, camera and lighting all matter. Make a sample at the intended size and test it before ordering a batch. For production steps, use our [printing and engraving checklist](/guides/print-engrave-test-qr-pet-tag).

## 3. Choose a visible, suitable attachment

For luggage, place a tag on the handle and a copy inside. For keys, use a durable keyring tag. For pets, choose a collar or harness attachment suitable for the individual animal and ask a veterinarian or qualified fitter if unsure. Do not let a tag interfere with the fastening.

QRChat supplies the code and chat service. You arrange printing or engraving with your chosen maker. Our [pet collar guide](/use-cases/pets-and-collars) shows design ideas and the actual creation form; illustrations are not products offered for sale.

## 4. Test the full contact route

1. Scan the finished tag using another phone that is not signed into your account.
2. Check that the link opens the intended QRChat conversation and the code is activated.
3. Send a message and reply from the owner's account.
4. Enable your preferred available notification channel and confirm that the test message reaches you. Delivery depends on your settings, permissions and connectivity.
5. Try the location button. After confirmation and any required browser permission, the finder can send a single current location point. It does not start live tracking. A landmark or map link is another option.

Check the tag again after wear or damage. Keep access to your account. If you delete or disable the code, the printed tag no longer provides its intended contact route. Reprint the same active code when replacing the physical tag.

## Cost, languages and limits

As of 3 November 2026, the first **10 QR codes are free**; each additional pack of 100 codes costs **EUR 10**. Physical tag production is separate. Check the [current pricing](/#pricing) before ordering.

The interface supports 35 languages. This does not mean that messages are automatically translated: a finder can write in their language, and you may need a separate translation tool.

For pets, combine contact tags with appropriate identification. Read [QR tags, ordinary tags, microchips and GPS compared](/guides/qr-pet-tag-vs-microchip-gps), or the [guide for someone who has found a pet](/guides/found-pet-qr-tag-what-to-do).
