Are QR code pet tags legal in the UK?
Short answer: A QR tag is legal to use, but for dogs it doesn’t meet the law on its own. Under the Control of Dogs Order 1992, a dog on a road or in a public place must wear a collar with the owner’s name and address on it, or on a plate or badge attached to it. A QR code doesn’t show those, so they need to be on the collar or on a tag on it too.
This is general information, not legal advice. Check the current rules on GOV.UK or with your local council.
What does the law say for dogs?
- On a road or in a public place, a dog must wear a collar showing the owner’s name and address.
- Some working dogs are exempt, for example guide dogs, police dogs and dogs working livestock.
- A phone number isn’t required, but it helps.
- A QR or NFC tag adds ways to reach you. It doesn’t replace this.
The Order covers England, Scotland and Wales. For the full rules, including what counts as a valid tag, read our guide to dog ID tag law in the UK.
Why doesn’t a QR code count?
The Order asks for the name and address to be inscribed on the collar or on a plate or badge attached to it. A QR code only leads to your details after someone scans it, so nothing is actually written on the tag. The same goes for an NFC tag. That’s why the answer for dogs is “both”: an engraved tag or collar for the law, and a smart tag for everything else.
Where does the rule apply?
The Order’s words are “in a highway or in a place of public resort”: roads and pavements, and places the public go, such as parks and beaches. Your dog doesn’t need to wear the collar at home or in your own garden.
Which dogs are exempt?
The Order lists them: a pack of hounds, and dogs while being used for sporting purposes, for catching or destroying vermin, for driving or tending cattle or sheep, on official duty with the armed forces, HM Customs or the police, or in emergency rescue work, and dogs registered with Guide Dogs. The exemptions apply while the dog is doing that work.
What happens if a stray dog has no tag?
Every council in England, Wales and Scotland has an officer, usually called a dog warden, who deals with stray dogs. Under section 149 of the Environmental Protection Act 1990 the warden can seize a dog they believe is a stray. If the collar shows an address, the council writes to it; if the dog isn’t claimed within seven clear days of that notice, it can be rehomed. A readable address on the collar is the quickest way to make sure that letter reaches you.
What about cats and other pets?
The collar rule doesn’t apply to cats. Cats in England must be microchipped and registered by 20 weeks old, including cats that stay indoors (the Microchipping of Cats and Dogs (England) Regulations 2023). Dogs across the UK must be microchipped and registered by 8 weeks old, and you can be fined up to £500 if your pet isn’t chipped when it should be. A visible tag still helps a neighbour reach you quickly, because a microchip can only be read with a scanner.
How do you stay legal and easy to reach?
- Put your name and address on an engraved tag, or on the collar itself.
- Add an NFC + QR tag so a finder can contact you without seeing your number.
- Keep your pet’s microchip details up to date as well. You’re responsible for telling the database when you move or change your number.
How does Taggzi handle it?
A Taggzi tag opens your pet’s page when it’s tapped or scanned, with no app for the finder. You choose what shows, including whether your phone number appears. Taggzi Pro adds private voice and video calls from the finder’s browser, so no number is shared. Keep an engraved tag, or your name and address on the collar, to meet the rule for dogs. Order a Taggzi tag for £2.99 plus delivery.

FAQ
Can I use only a QR tag on my dog in the UK?
No. Add your name and address to the collar or to a tag on it, alongside the QR code.
Does a QR tag replace microchipping?
No. Microchipping is separate and is a legal requirement for dogs, and in England for cats too. A tag helps people reach you before anyone needs to scan the microchip.
Does the finder see my address on a Taggzi profile?
Only if you choose to add it to the pet profile.
