Lost & Found QR Tag Generator

Put a tag on your keys, backpack, laptop, or pet collar. Whoever finds it scans the code and their phone offers to call, text, or email you — directly, with no subscription service in between. The tag never expires, and nothing you type here leaves your browser.

How to make a lost & found tag

  1. Name the item and choose how the finder should reach you — call, text, email, or your own web page.
  2. Add an optional reward line; it measurably improves return rates.
  3. Test-scan the preview with your own phone, then download and print. Laminate tags for keychains and collars.

Choosing what to expose

Anyone who scans the tag can read the contact you put in it — so choose deliberately. A phone number gets your item back fastest; an email alias keeps your identity private; a web page you control lets you change the contact later without reprinting (point the code at your page, update the page anytime). For children's items, prefer a parent's number over a name-plus-school combination.

Frequently Asked Questions

What does the finder see when they scan the tag?

Exactly what you chose: their phone offers to call you, opens a pre-filled text message, starts an email with "Found: [your item]" as the subject, or opens your web page. No app, no account, no middleman service — the finder contacts you directly.

How is this different from paid lost-and-found tag services?

Subscription tag services route the finder through their servers and stop working when you stop paying. This tag encodes your contact method directly — it works forever, costs nothing, and no company sits between you and the person holding your keys.

What contact details should I expose on a tag?

A phone number is fastest for the finder but is readable by anyone who scans the tag. If that concerns you, use a dedicated email alias (found@your-domain), a Google Voice-style number, or a simple web page you control. Avoid putting your home address on a tag for keys.

What if I change my phone number?

The tag is static, so regenerate and reprint it — it takes a minute and costs nothing. That trade-off is what makes the tag free and dependency-free: there is no account to renew and no service that can shut down.

Does it work for pet collars?

Yes — the same tag works on a collar: put the pet’s name as the item, your phone as the contact, and print at 25 mm or larger so it scans easily on curved surfaces. Laminate it or use a waterproof sticker pouch.

What size should I print?

At least 2 x 2 cm for flat items (laptops, bottles, notebooks) and 2.5 cm or larger for curved surfaces like keychains and collars. Download the SVG for crisp printing at any size, and test-scan the printed tag before relying on it.
