The Details That Come Home With Them: Running a 2026 Pet ID Audit
Most of us think about pet ID for about four minutes a year: when the insurance renewal lands, when the vet asks for a chip number, or when someone posts a found dog on a local Facebook group. The rest of the time, the chip sits quietly under the skin and the tag jingles away on the collar. That is fine until the day it is not. This is the BYO Pet version of an ID audit: not a scare story, just a sensible check of the details that travel with your pet every single day.
Start with the chip, not the certificate
A microchip is a passive radio-frequency device, not a GPS tracker. It does not beam your pet’s location to an app. What it does is give a vet, dog warden or rescue a number to look up. That look-up only works if the chip is registered to the right keeper, with the right contact details, on a UK pet microchip database.
Find the certificate or the registration email and check four things: the chip number, the database name, the owner name and the address. Then check the phone number and email address. A stale email is surprisingly common after a house move or a change of broadband provider. If you cannot find the paperwork, ask your vet to scan the chip and give you the number, then contact the database directly. If you are unsure which database holds the record, your vet or the original implanter should be able to point you in the right direction.
If you rehomed your pet from a rescue, make sure the keepership was actually transferred into your name, not just updated with a new address. If you have moved, changed your phone number or changed your name, update the database before you do anything else on this list. The chip itself never needs changing; the record does.
The tag rules people half-remember
For dogs in a public place, the law in England and Wales expects a collar with a tag showing the owner’s name and address. That comes from the Control of Dogs Order 1992, and it applies to everyday walks, not just days out. There are exemptions for some working dogs, but most pet dogs should have a tag. A mobile number is not a legal requirement, but it is the detail a finder will actually use, so add one.
Check the tag itself. Is the lettering still readable? Has the ring worn thin? Does it still show an old address? If your dog wears a harness, the tag still needs to be on a collar unless your local authority or the specific rules for your situation say otherwise. For cats, there is no equivalent legal tag requirement, and a collar is optional. If you use one, choose a quick-release or safety collar and make sure it fits properly. The chip is the cat’s main permanent ID.
What UK law expects in 2026
Dogs in the UK must be microchipped by eight weeks of age, and the keeper’s details must be kept up to date on a compliant database. In England, cats must be microchipped by 20 weeks of age; that requirement came into force in 2024 and is now part of normal cat ownership. Rules vary across the UK, so if you are in Scotland, Wales or Northern Ireland, check the current guidance for your nation rather than assuming England’s cat rule applies exactly.
The practical point is simple: a chip that is not registered, or is registered to an old address, is not doing its job. Local authorities can issue notices and fines where details are not kept current, but the bigger risk is quieter than that. A finder takes your pet to a vet, the vet scans a chip, and the phone number on the record is dead. That is the moment the audit matters.
The house-move checklist
When you move, redirecting your post is not enough. Update the microchip database first, then the tag, then your vet, insurer and any pet-service providers who hold your details. Tell your old vet you have moved and register with a new one if needed. If your pet is on regular medication, update the pharmacy or online supplier too. If you use a groomer, daycare or dog walker, send them the new address and emergency contact.
It is also worth updating the emergency contact on your pet’s record. If your mobile is off or you are in hospital, who should a vet call? A second number is a small thing that can save hours.
A lost-pet plan you can actually use
Do not wait for the panic. Make a one-page sheet now with a recent clear photo, the chip number, the database name, your vet’s details, any medication or behaviour notes, and two contact numbers. Keep a copy in your phone and one in the pet bag. If your pet goes missing, call your local vet practices, the council dog warden and the microchip database. Mark the chip record as lost or missing if the database offers that option. Post in local groups with the photo and chip number, but keep some identifying detail back so you can verify ownership.
Posters still work. Put them at the ends of your street, at local shops and at the vet. If someone finds your pet, ask them to take it to a vet for a scan rather than meeting in a car park. A scanned chip is the quickest way home.
The five-minute reset
Once every six months, pick up the collar, read the tag, open the chip certificate and check the database record. It is a dull little admin job, but it is the most useful piece of pet kit you already own. Bring your pet along for the good days; make sure the details can bring them home on the bad ones.
