Register your cat's microchip before you need it
A microchip does nothing on its own. Registering it links the chip number to your contact information, so a scan at a shelter or vet turns into a call to you, not a dead end. With United Pet Club it's free for the life of your cat.
Five steps to register your cat's microchip
1
Step 1: Get your cat microchipped
Your vet implants the chip during a regular visit. It takes a moment and most cats barely react. You'll leave with a record showing the chip's unique ID number: photograph it or file it somewhere you won't lose it.

Step 2: Pick a registry
The chip's manufacturer may run its own database, but you can register anywhere that accepts the chip's ID. Register a microchip with United Pet Club to get a registry that takes any brand and checks against the AAHA universal lookup tool that shelters use.

Step 3: Fill in your cat's details and yours
You'll enter the chip ID (typically 15 digits), your cat's name, breed or coloring, age, and a photo, along with your name, address, phone number, and email. Indoor only cats need this just as much as cats that go outdoors: an open door or a startled bolt out a window is all it takes.

Step 4: Cover any registration cost
Some registries charge a one-time or recurring fee, and others are free. Check what you're agreeing to, including whether the registration lapses if you don't renew it.

Step 5: Update it after every move
Change your address, phone number, or email in the registry as soon as they change, and again after every move. A chip registered to an apartment you left two years ago won't get you a phone call today.
Why registration matters more for cats than owners assume
Cat owners sometimes skip registration because their cat never goes outside. Indoor cats get out anyway: through a cracked door, a torn screen, a moving day with the front door propped open. A cat that's never been outdoors is often more likely to run and hide than to come when called once it's out, which is exactly when a registered microchip matters most. Collars and pet ID tags can help a neighbor identify your cat on sight, but cats are notorious for shedding collars, and a chip doesn't come off.
Shelters and vet clinics scan every stray cat that comes through the door, whether it arrived as an owner surrender, a trap from a colony, or a walk-in. If the chip is registered, that scan produces your phone number in seconds. If it isn't, the cat gets treated as unowned, which starts a much slower process.
If you adopted a cat that already has a microchip, don't assume the registration transferred with the paperwork. Contact the registry listed for that chip and request an ownership update using your adoption record as proof, or register the microchip fresh with United Pet Club. A current registration takes priority over an old one. A cat with no chip at all can still get a free profile: register your cat now and add the chip number after the vet visit.
What a registered chip does for your cat
Backs up a collar that comes off
Cats slip collars constantly, whether by design, with a breakaway safety buckle, or by accident. The microchip stays put even when the collar doesn't.
Speeds up shelter intake
A scan that matches a registered record can mean same-day contact instead of your cat sitting on a stray hold waiting to be claimed.
Covers indoor cats too
Registration doesn't assume your cat goes outside. It just means that if your cat ever does get out, accidentally or not, there's a way back.
Moves with you
Update your contact information after a move and the registration stays current. The chip itself never needs to be touched again.
Questions cat owners ask about microchip registration
How do I know if my cat's chip is already registered?
Check the paperwork from your vet or the shelter you adopted from; it usually lists the registry and ID number. If you can't find it, register with United Pet Club anyway. A newer registration takes precedence over one you can't locate or verify.
Does an indoor cat really need a registered microchip?
Yes. Most lost indoor cats got out by accident, not by habit, which makes them harder to recover by sight alone. A registered chip still works even if your cat bolts without a collar.
What happens when a shelter scans my cat's chip?
Staff read the chip's ID number and check it against the registry it's recorded in. If your contact details are current, they call or email you directly instead of holding your cat as a stray.
Do I need to re-register my cat's microchip after adopting her?
You need to update the ownership record, even though the cat already has a chip from a previous owner or shelter. Contact the existing registry with your adoption paperwork, or register fresh with United Pet Club.
Do I need to re-register when I move?
You don't need a new chip or an entirely new registration, but you do need to update your address, phone number, and email. The registry is only as useful as the contact information behind it.
Where can I register my cat's microchip in the US?
With United Pet Club, free for the life of your cat. Any brand of chip qualifies, your record is searchable 24/7 through the registry and the AAHA universal lookup, and updating your details after a move never costs anything.
