Register your cat's chip before the door is left open
A microchip does nothing by itself. Registering it ties the chip number to your contact details, so a scan at a rescue centre or vet surgery becomes a call to you rather than a dead end. With United Pet Club it is free for the life of your cat.
Registering your cat's microchip, step by step
1
Step 1: Have your cat chipped
Your vet implants the chip during an ordinary appointment. It takes a moment and most cats barely notice. You leave with a record of the chip's unique ID: photograph it or file it where it will not vanish.

Step 2: Pick a registry
The chip's manufacturer may run its own database, but you can register anywhere that accepts the number. United Pet Club takes any brand and feeds into the AAHA universal lookup that shelters check.

Step 3: Fill in your cat's details and your own
Enter the chip ID (typically fifteen digits), your cat's name, breed or colouring, age, and a photo, along with your name, address, phone number, and email. Indoor cats need this every bit as much as roamers: one open door is all it takes.

Step 4: Check any registration cost
Some registries charge, once or on repeat, and others are free. Read what you are agreeing to, including whether the registration lapses if left unrenewed.

Step 5: Update after every move
Change your address, phone number, or email in the registry as soon as they change, and again with every move. A chip pointing at a flat you left two years ago will not get you a phone call today.
Cats need this more than most owners think
Owners of house cats often skip registration on the grounds that the cat never goes out. Indoor cats get out regardless: a door on the latch, a torn window screen, a removal van with the front door propped wide. A cat that has never been outdoors tends to bolt and hide rather than come when called, which is exactly when a registered chip earns its place. In England the question is settled anyway, because cat microchipping became compulsory from June 2024, with owners expected to chip and register cats by twenty weeks of age. Collars and pet ID tags help a neighbour recognise your cat on sight, but cats shed collars with great talent, and a chip cannot be shed.
Rescue centres and vet surgeries scan every stray cat that arrives, whether handed in, trapped from a colony, or carried through the door by a passer by. A registered chip turns that scan into your phone number within seconds. An unregistered one leaves the cat treated as unowned, and a far slower process begins.
Adopted a cat that already carries a chip? Do not assume the registration moved with the adoption papers. Contact the registry listed for the chip and ask for an ownership update with your adoption record as proof, or register the microchip afresh with United Pet Club, since a current registration takes priority over an old one. A cat with no chip at all can still have a free profile: register your cat now and add the chip number after the vet visit.
What a registered chip does for a cat
Backs up the collar
Cats lose collars constantly, whether through a breakaway buckle doing its job or plain mischief. The chip stays put when the collar does not.
Speeds up intake at rescues
A scan matching a registered record can mean same day contact instead of your cat waiting out a stray hold.
Covers indoor cats too
Registration makes no assumptions about lifestyle. It simply means that if your cat ever does get out, there is a road back.
Moves house with you
Update your contact details after a move and the registration is current again. The chip itself never needs touching.
What cat owners want to know
How do I know whether my cat's chip is already registered?
Check the paperwork from your vet or the rescue you adopted from; it usually names the registry and the ID number. If it is nowhere to be found, register with United Pet Club anyway. A newer registration takes precedence over one you cannot locate or verify.
Does an indoor cat honestly need a registered chip?
Yes. Most lost indoor cats got out by accident rather than habit, which makes them harder to recover by sight alone, and in England chipping pet cats is now the law in any case. A registered chip works even when your cat bolts without a collar.
What happens when a rescue centre scans my cat?
Staff read the chip's ID and check it against the registry holding it. If your details are current they ring or email you directly, rather than holding your cat as a stray.
Do I need to re-register the chip after adopting a cat?
You need the ownership record updated, even though the chip itself came with the cat. Contact the existing registry with your adoption paperwork, or register afresh with United Pet Club.
Do I need to re-register after moving house?
No new chip and no new registration, but the address, phone number, and email do need changing. The registry is only as useful as the contact details inside it.
How do I register my cat's microchip in the UK?
Create a free United Pet Club account, enter the chip number from your paperwork, and add your contact details. It costs nothing for the life of your cat, works with any brand of chip, and with England now requiring cats to be chipped, a registered record is what turns the implant into a way home.
