Disclosure: we make one of the tags on this page. Supernormal builds the PawTag, so treat our opinion of it with the scepticism it deserves — we have set out below exactly what it does badly as well as what it does well, and where a rival or a plain engraved tag is the better buy. All prices were checked on 30 July 2026 and are quoted in the currency the seller quoted them in.
The short version
Most guides to this topic try to crown a single winner. That is the wrong shape for the question, because the three kinds of dog ID tag do genuinely different jobs and the best answer for most owners is a combination rather than a single product.
| If you want… | Buy |
|---|---|
| The cheapest thing that satisfies the law | An engraved metal tag with your name and address on it |
| Details a finder can read without squinting, and that you can change | A smart QR/NFC tag |
| To see where your dog is right now, without waiting for a stranger | A GPS tracker such as Tractive |
| The setup we would actually recommend | An engraved tag and a smart tag on the same collar |
That last row matters. An engraved tag works with a dead phone, no signal and a finder who has never scanned a QR code in their life. A smart tag carries far more information and can be updated when you move house. They cover each other's weaknesses, and together they cost less than most GPS subscriptions.
The three kinds of dog ID tag
| Engraved metal | Smart QR/NFC | GPS tracker | |
|---|---|---|---|
| Up-front cost | Lowest — a one-off, single-figure spend | Free to around $25 | Highest — hardware plus subscription |
| Ongoing cost | None | Usually a subscription for the useful features | Subscription, always |
| Battery | None | None | Days to weeks, must be charged |
| Details updatable | No — re-engrave | Yes, instantly | Yes |
| Needs a finder | Yes | Yes, with a smartphone | No |
| Tells you where the dog is | No | Only when scanned | Yes, live |
| Fails when | Details go out of date | Finder has no phone or no signal | Battery is flat |
Notice that none of the three is strictly better. Engraved tags fail slowly, as your details drift out of date. Smart tags fail at the moment of use, if the person holding your dog cannot or will not scan. GPS trackers fail on a schedule, whenever you forget to charge them.
Before you buy: what has to be on the tag
Worth knowing before you spend anything, because a good tag with the wrong information engraved on it is a wasted purchase.
In the UK, article 2 of the Control of Dogs Order 1992 requires a dog in public to wear a collar bearing the owner's name and address — not, as almost everyone assumes, a phone number. In the United States there is no federal tag law, but county licensing and rabies tag rules usually apply. In Australia, New Zealand and Canada it is generally council registration. In every case you also want a phone number on there, because that is what actually gets your dog home the same afternoon.
We go through the wording, how to fit it on a small disc, and whether to include your dog's name in a separate guide: what to put on a dog tag.
The best dog ID tags in the UK
Supernormal PawTag — smart QR + NFC tag
Our own product, so weigh this accordingly. It is a waterproof metal tag with a QR code and an NFC chip; a finder scans or taps it with any smartphone and sees the pet profile you control — contact details, medical notes, and instructions for what to do. You can mark the dog as missing, which triggers alerts to nearby owners, vets and kennels.
- Tag: free on a paid plan; £9 for the engraved version
- Plans: Free £0 · Single £2.99/month · Unlimited £3.99/month (20% off annually)
- Good at: unlimited information, changed in seconds; no battery; the cheapest smart-tag subscription we found in either market; community alerts when a dog goes missing
Where it falls short, honestly:
- It is not a tracker. You learn nothing about your dog's location until somebody scans the tag. If your dog is loose in a field at 2am, a GPS tracker will help you and this will not. If that is your main worry, buy a Tractive instead.
- It depends on a stranger having a smartphone and choosing to use it. Most people do, but "most" is not "all", and an older finder or a flat battery breaks the chain.
- The useful features are behind the subscription. If your plan lapses, you are left with an attractive metal disc and no engraved details on it — which is precisely why we tell people to pay the extra £9 for engraving, or to wear a separate engraved tag alongside.
- Engraving costs extra. The free tag is genuinely free, but the version that satisfies the 1992 Order on its own is the £9 one.
If you want the longer head-to-head against our closest rival, we keep a dedicated page: Crumb vs Supernormal. You can order a free tag here.
Crumb — smart QR tag
The main UK competitor and a good product. Same basic idea: a free waterproof QR tag with an online profile, plus a paid tier that adds alerts and extras. Crumb's distinctive feature is SnoutID, a nose-print record intended to prove ownership in a theft dispute, which we do not offer.
- Tag: free
- Plans: Free £0 · Premium £9.00/month, or £7.50/month billed annually · Premium Plus £18.00/month, or £15.00/month annually
- Good at: SnoutID; automatic missing posters; unlimited tag replacements on Premium; a genuinely useful free tier
- Trade-offs: QR only, no NFC tap; Premium is roughly two and a half times our Single plan; the free tier holds back most of the recovery features
A plain engraved metal tag
Unglamorous, and still the single best value in pet ID. A one-off cost of a few pounds from any pet shop, supermarket or online engraver, no subscription, no battery, and it works for a finder who has never heard of a QR code.
- Good at: cost; reliability; satisfying the 1992 Order on its own
- Trade-offs: the details are frozen at the moment of engraving. Move house, change your number, or add a note about medication and you are buying another tag. Thin aluminium discs also wear smooth surprisingly fast — check yours is still legible, because a worn tag is a tag that does nothing.
If you buy nothing else on this page, buy one of these. It is the floor, not the ceiling.
The best dog ID tags in the US
The American market is structured differently: smart tags here more often charge for the tag and less often for a subscription, which changes the maths considerably if you keep a tag for years.
PetHub — smart QR tag
- Tag: $29.99 for the silicone glow-in-the-dark tags
- Plans: Basic free · PetHub+ $29.99/year or $3.99/month · Lifetime PetHub+ $199 one-off
- Good at: the longest track record of any QR tag company; a found-pet hotline and call centre, which is a genuinely different offering; the lifetime option is good value if you keep it for more than seven years
- Trade-offs: you pay for the tag and the plan; the strongest recovery features sit on PetHub+
ByteTag — smart QR tag, no recurring fee
- Tag: $19.95 for the Slide, $24.95 for the silicone and metal tags
- Good at: no subscription is advertised at the point of sale, which for a lot of owners is the whole argument — pay once, done. Attractive designs and unlimited contact details on the profile.
- Trade-offs: a one-off payment funding an online service indefinitely is a business model worth thinking about before you rely on it long-term. Ask what happens to your profile if the company changes hands.
GoTags and Dog iD — engraved
GoTags sells a large range of engraved dog ID tags at roughly $8.95–$14.99, and is the straightforward budget answer in the US. Dog iD — the pet arm of ROAD iD, on its own domain — sells engraved collar IDs and AirTag holders from around $20, with heavier construction aimed at working and outdoor dogs.
Both are US-based and priced in dollars. For UK, Australian or New Zealand readers that means shipping time, exchange rate and possibly customs on a tag you can buy locally for less — which is why they sit in this section and not the UK one.
Australia, New Zealand and Canada
We have not found a local smart-tag brand in these markets with pricing we can verify, so rather than pad this out with guesses: the QR tags above ship internationally, Tractive and AirTag are sold globally, and engraved tags are cheap and available everywhere.
The one local thing to get right is registration. All three countries generally work on council or municipal registration — you register the dog, get a numbered registration tag, and the dog is expected to wear it. That tag is a reference number, not your contact details, so it does a different job from an ID tag and does not replace one. Your council's website is the authority on what is required where you are.
GPS trackers and AirTags — the other category
Tractive — GPS tracker
Not an ID tag at all, but it belongs here because it is what people are often really asking for. A cellular GPS unit that clips to the collar and shows live location in an app.
- Device: €69 at the time of checking. Tractive prices in local currency at checkout, so expect roughly £60 or the local equivalent.
- Plans: Basic from €13/month monthly, or about €7/month billed annually; Premium from around €8/month annually
- Battery: Tractive claims up to 14 days on the DOG 6 with power-saving on, or up to 6 days without; the larger XL claims up to 42 days and 20 days respectively
- Good at: the one thing no tag can do — telling you where your dog is without a stranger's involvement. Worth it for escape artists, working dogs and anyone with a runner.
- Trade-offs: by far the most expensive option, in hardware and in subscription. Needs charging. And it carries no owner information, so it satisfies no tag or registration requirement anywhere and does not help the person holding your dog. A tracker is an addition to a tag, never a replacement.
An Apple AirTag in a collar holder
Popular, cheap, and more limited than most owners expect. An AirTag has no GPS and no SIM: it reports its position only when it drifts within Bluetooth range of somebody else's iPhone. In a busy city that can work well. On a hillside at dusk it will show you the last place your dog was near a person, which is not the same as where your dog is.
There are also real safety considerations with hard plastic holders on a collar. We wrote about those separately: the hidden risks of using AirTags on dogs.
How we compared these — and what we did not do
Being straight about method is more useful than claiming a laboratory.
What we did: we checked every price directly on the seller's own site or checkout on 30 July 2026 and quoted it as found, including the currency it was quoted in. We verified which products actually exist and which of them ship where. We read the underlying legislation rather than repeating other people's summaries of it. We use our own tag daily, and we see what happens when a real tag is scanned by a real finder.
What we did not do: we have not run a controlled durability test — no tumble-testing, no abrasion cycles, no measured legibility after six months on a working dog. We have not independently verified Tractive's battery claims, Crumb's SnoutID accuracy or PetHub's recovery statistics; those figures are the companies' own and are labelled as such. We could not verify pricing for any local smart-tag brand in Australia, New Zealand or Canada, so we have not named one. And we cannot be a neutral judge of our own product, which is why the PawTag section leads with what it does badly.
Three things we noticed while checking, which say something about the state of this genre: a number of widely-cited "best dog tag" roundups recommend products that do not exist, link to pages that have not resolved for months, or quote dollar prices at British readers without saying so. If a guide cannot tell you what a tag costs today, it has not looked.
So which should you buy?
For most owners, in any country: a plain engraved tag carrying your name, enough of your address to identify it, and a mobile number — plus a smart tag on the same collar for everything that will not fit on a disc and everything that changes. In the UK that is a few pounds up front and under £3 a month. In the US, either PetHub or ByteTag alongside a $9 GoTags disc.
Add a GPS tracker only if your dog actually bolts. It is the most expensive option by a wide margin and it solves a problem many owners do not have — but if yours is a runner, nothing else comes close, and you should read about how tracking works before choosing one.
And whatever you buy, check it. Look at your dog's tag now: is the engraving still readable, is the number still yours, is the split ring still closed? The most common reason a tag fails is not the tag. It is that nobody has looked at it in three years.
