How it works
1. Put it on their collar.
Attach the tag to your dog's collar, then set up their profile in about a minute.
2. Add what matters.
A photo, how finders can reach you, and notes like “nervous with other dogs” or “needs daily medication”.
3. Anyone can scan it.
If your dog gets lost, whoever finds them scans the tag with their phone camera, sees the profile and contacts you straight away.

What owners say
“Brilliant service from start to finish. I asked if they could point the QR code at my own custom web address instead of the standard page, and they sorted it without any fuss. Arthur was quick to reply and kept me updated the whole way through, which made it all really simple. The tag itself is really good quality and the QR code works flawlessly. Highly recommend.”

“Love this tag. The no subscription is so good. Once you’ve paid for your tag, that’s it, no more cost. You can easily change any messages as well. For example temporary medical issues or if you are away and a friend is looking after them you can add their details. What’s not to love!”

Questions
UK law: what your dog's ID tag must show
When your dog is in a public place, the Control of Dogs Order 1992 says it must wear a collar with your name and address on it, or on a tag attached to it. That applies even if your dog is microchipped.
A QR code doesn't show your name and address on its own, so add them to the back of your PetTag (+£3): your surname, house number or name and postcode, in black letters, and one tag does both jobs. Or keep an engraved tag or a collar with your details on alongside it. Either way, the QR code adds what an engraved tag can't: a photo, up-to-date contact options and a way for finders to message you.
How it compares with an engraved tag, a GPS tracker and a microchip
It works alongside the microchip, not instead of it.

Other UK QR tags we checked in September and October 2026 cost from £4.99 (plus delivery) to £29.99 a tag, or £1.98 to £2.99 a month. See them side by side.
Is a QR code dog tag legal in the UK?
Yes, with your details. In the UK your dog must wear your name and address on its collar or a tag when it's in public, and a QR code doesn't show them on its own. Add your surname, house number and postcode to the back of your PetTag for £3, or keep an engraved tag or a collar with your details on too. The QR code adds a photo, your contact options and lost mode.
Personalised dog tagsWhat size is the tag? Will it suit a small dog or a puppy?
The standard tag is 40 mm across (45 mm with the loop), 5 mm thick and about 4 g. For small breeds there's the Small (34 mm, about 3 g), and for toy breeds and young puppies the Mini (29 mm, about 2 g), at the same price. Smaller sizes are made to order and posted within 2 working days.
Small dog and puppy tagsMy dog is microchipped. Does it still need a tag?
Yes. A microchip is a separate legal requirement, and it can only be read with a scanner at a vet or the council. In public your dog must also wear your name and address on its collar or a tag, which anyone can read on the spot.
What happens when someone scans my dog's tag?
Your dog's profile opens in their phone's browser, with ways to contact you. They can send you a message with their location, even if you keep your number private.
8 more questionsMore questions
Should my dog's name be on the tag?
The law doesn't ask for it, and some owners prefer to leave it off an engraved tag. With a PetTag, your dog's name appears on the profile that finders see after scanning.
What if the tag gets lost?
Order a replacement and move your dog's profile onto the new tag. All the details stay as they were.
How many tags do I need?
One tag per dog is enough. A second is handy for a harness or a spare collar.
Is a PetTag a smart dog tag?
Yes, a simple one. It uses a QR code that any phone camera can read, so there's no app, battery or charging. It doesn't track where your dog is like a GPS tracker does: it lets whoever finds your dog reach you straight away.
Is there a subscription?
No. You pay once, from £10 with free UK delivery, and your dog's profile and lost mode stay free for life.
What if PetTag ever closes?
We'd email you at least 6 months before, and your dog's page would keep working the whole time. You can download its details from your account any time, and anything printed on the back works with no website at all.
All our promisesWhat's the best QR code dog tag in the UK?
We make PetTag, so weigh that, but here's how it compares. For a QR tag with no subscription, the lowest price in our comparison is CollarCode, £4.99 plus delivery. PetTag is £10 with free UK delivery, posted the next working day, and finders can message you without your number on show; most other one-off tags are £19.99 to £29.99. For one tag that also shows your name and address for the law, PetTag puts them on the back for £13 in all, and Pet-Tags (£19.99) engraves them; for a metal tag, look at Paw ID (£29.99).
UK QR pet tags comparedWill the QR code wear off?
No. The code is set into the face of the tag, not printed on top, so mud, rain and swims won't rub it off.
