Do Microchipped Dogs Still Need an ID Tag in the UK?
Yes. UK law requires dogs in public to wear a collar with an ID tag showing the owner's name and address, even if they're microchipped. Here's why both matter.

Yes, in the UK a microchipped dog still legally needs an ID tag. Under the Control of Dogs Order 1992, any dog in a public place must wear a collar with the owner's name and address on it (or on a tag). Microchipping is a separate legal duty, not a replacement for the tag.
Two separate laws, two separate jobs
It's easy to assume a microchip covers everything, but the two requirements come from different rules and do different things.
The collar and tag requirement comes from the Control of Dogs Order 1992. It means anyone who finds your dog can read your details on the spot and get your dog home, no scanner needed.
Microchipping is required separately under the Microchipping of Dogs (England) Regulations and equivalents across the UK. Since 2016 all dogs over eight weeks must be chipped and registered on an approved database. The chip is read by a scanner at a vet, rescue or warden, and links to your registered contact details.
So a chipped-but-tagless dog is still breaking the law the moment it's in public. The maximum fine for not having the legal tag can run into hundreds of pounds, and the fine for an unchipped dog is separate again.
What the tag must legally say
The law is specific: the tag (or the collar itself) must show the owner's name and address. A phone number is not strictly required by law, but it's the single most useful thing you can add, because most people who find a dog will call before they post anything.
You do not have to put the dog's name on the tag, and many people choose not to, since it lets a stranger call your dog by name. For the full breakdown of wording and what to include, see UK Dog ID Tag Law: What Must Be on Your Dog's Tag.
When you're choosing dog id tags, think about how the engraving will wear. Deeply engraved metal lasts longer than shallow stamping, and a slider tag that sits flat against the collar won't jingle or snag.
Why the microchip is still the backstop
A tag does the everyday work, but collars come off. A dog can slip a collar in a hedge, snap a cheap clip, or wriggle free at the worst moment. That's exactly when the microchip earns its keep, because it can't be lost.
The one job a chip can't do is update itself. A microchip is only as good as the details registered to it. If you've moved house or changed your number and not updated the database, a scan leads nowhere. It's worth checking your registration once a year, and definitely after any move.
Tag and collar together: the practical setup
The most reliable everyday combination is a clearly engraved tag on a comfortable, well-fitted collar. Some owners go a step further with personalised dog collars that have details embroidered or printed straight onto the strap, which acts as a backup if the hanging tag is ever lost.
A collar like the nylon bohemian striped checkered collar is the kind of everyday strap a tag rides on; just make sure it fits with two fingers' space and isn't so worn the buckle could fail.

The short answer to keep in mind
Chip and tag are not either-or. The tag gets a found dog home in minutes; the chip is the permanent fallback for the day the collar fails. Run both, keep your chip details current, and you've covered the law and the worst-case scenario at once.
Common questions
Does my dog need a tag on private land like my own garden?
The legal collar-and-tag requirement applies to dogs in a public place. On fully enclosed private property it doesn't strictly apply, but a quick dash out of an open gate is exactly when a tag matters, so most owners leave it on.
Are working dogs exempt from the tag rule?
There are specific exemptions, such as for dogs while being used for sporting purposes, on official duties or working livestock. For the average pet dog out on a walk, the collar-and-tag rule applies.
How often should I check my microchip details are correct?
At least once a year, and always after moving home or changing your phone number. The chip only helps if the database has your current contact details; an out-of-date record is as good as none.
Can the legal details go on the collar instead of a separate tag?
Yes. The law allows the name and address to appear on the collar itself, for example embroidered or printed, rather than on a hanging tag. Either satisfies the requirement as long as the details are legible.
