Jumpers and cardigans go first
They come off at morning break, on the field, in the hall, and they get put down somewhere other than a peg. Label them before anything else, and label every one you own rather than the newest.
Thirty children, one identical jumper. A printed name gets it back from the lost property box, and the QR code gets it back when it never reaches the lost property box at all.

The school problem
Every other garment your child owns is distinguishable at a glance. Uniform is deliberately not, which is why one jumper in a cloakroom of thirty is genuinely unidentifiable without a label.
They come off at morning break, on the field, in the hall, and they get put down somewhere other than a peg. Label them before anything else, and label every one you own rather than the newest.
In the cloakroom a name is enough, because the office knows which child it belongs to. On the bus, in the park after school or at a fixture at another school, a name tells a stranger what your child is called but not how to reach you. That gap is what the code closes.
New phone, new second contact, new after-school arrangement. One profile sits behind every label in the pack, so you change it once online and every jumper already labelled is current.

Getting set up
Do it once in August and you are done until the next growth spurt.
Count what you own rather than what the school list says, including last year's jumper that still fits. Undercounting on the first order is the single most common mistake.
Iron-on labels go onto suitable garment fabric or onto the care tag already inside the item. Water bottles and lunch boxes need a sticker on a clean, dry hard surface, and those are not on sale yet.
Enter the bundle code from your pack, add your child's first name and the number you want a finder to call. Add a second contact for the days you cannot answer.
Choose whether a finder sees your details or only a message form. For school-age children most parents publish a first name and one number, and nothing that identifies the school.
What a finder sees
Someone finds a coat on a bus, at a park, at a swimming pool. They want to return it and have no idea how. They point a phone at the code and reach you directly, with nothing to install and no account to make. The school office never has to be involved.

Questions parents ask
For a primary child on a weekly wash, most families land somewhere around 25 to 30 once uniform, PE kit, coats, bottles and bags are counted. Secondary is usually fewer garments but more equipment. The name label calculator on this site has a school preset that counts it properly, and it is free with no email required.
Inside school, yes, and we would rather say so. A printed name is enough for the office to match a jumper to a child, and any name label does that job. The code matters for the items that go missing somewhere the school cannot help: a coat left on a bus, a PE bag at an away fixture, a bottle at the park after pick-up.
Iron-on labels apply either to suitable garment fabric or to the heat-safe care tag already sewn into the item. The care tag is usually the tidier choice on school knitwear, because it leaves the outer fabric untouched and the label sits where a teacher already looks.
Each pack carries one contact profile, so the printed first name and the profile behind it belong to one child. For siblings, most families buy the 50 pack and set up a second profile, or order a pack each so the name printed on the label is right.
Only if you choose to publish it. You can show your saved details to anyone who scans, or hide them behind a message form so a finder can contact you without ever seeing your number. That setting is yours and can be changed at any time without replacing labels.
Yes, and this is the main reason to use a coded label rather than a printed phone number. The label points at a profile rather than at a number, so you update the profile online and every jumper already labelled is immediately current.
