UK Dog ID Tag Law: What Must Be on Your Dog's Tag

By law in England, Scotland and Wales, your dog must wear a collar with a tag (or plate) showing your surname and address whenever they are in a public place. Including a phone number is not legally required but is strongly recommended, as it is the fastest way to be reunited with a found dog. Your name and address are the legal minimum; everything else is sensible extras.

What the law actually says

The requirement comes from the Control of Dogs Order 1992, which applies across England, Scotland and Wales. It states that a dog in a public place must wear a collar with the owner's name and address inscribed on the collar or on a tag attached to it. There are a few working exemptions (for example certain dogs used for sport, herding or pest control while actually working), but for the everyday pet owner the rule is simple: collar and ID tag in public.

Failing to comply can lead to a fine, so it is worth getting right. The address is the legal core; a postcode and house number is generally accepted as sufficient.

What to actually put on the tag

Here is the practical version of what most owners engrave on their dog id tags:

• Your surname (the law asks for name; surname is the norm).
• Your address, or at minimum house number and full postcode.
• A mobile number, ideally two if there is room.

That covers the legal duty and the fast-reunion goal in one small disc.

What to leave off

Do not put your dog's name on the tag. It sounds harmless, but a stranger who can call your dog by name can more easily coax it away, and it adds nothing useful for getting your dog home. A few more things to skip:

• Avoid "I am microchipped" as your only ID; it does not replace the legal tag.
• Skip cramming so much on that it becomes unreadable. Clear is better than complete.

Tag vs microchip: you need both

Separately from the tag law, it is a legal requirement in England, Scotland and Wales for dogs to be microchipped (from 8 weeks old) with your details kept up to date on an approved database. The microchip and the tag do different jobs: the chip proves ownership at a vet or warden, the tag gets your dog home quickly from a passing member of the public. You need both, and our guide Do Microchipped Dogs Still Need an ID Tag in the UK? explains why in detail.

A quick practical note worth flagging: keep your microchip details current after any house move or new phone number, because an out-of-date chip is one of the most common reasons strays are not reunited. If your vet has not scanned the chip in a while, ask them to check it is readable at the next visit.

Choosing a tag that lasts

A tag is only useful if it stays legible. When you compare options, think about:

• Engraving depth and material. Deep-engraved stainless steel or solid brass outlasts cheap soft alloys that rub blank in months.
• Noise. A silent or rubber-edged tag spares your ears (and your dog's).
• Fit. It should sit on the collar without dragging or catching.

If you would rather skip the dangling disc, a personalised dog collar with your details embroidered or engraved on a plate satisfies the same legal requirement neatly. Our Best Personalised Dog Collar UK (Engraved and Embroidered) guide compares those, and the wider Dog Walking & Travel hub covers the rest of your out-and-about kit. You can also browse the walk and travel range to sort collar and ID together.
