Found a pet? Look up its microchip for free
United Pet Club's pet recovery lookup is free and open to anyone, anywhere in the world. Use the Recover a Pet button at the top of any United Pet Club page to search a microchip, tag, tattoo, or passport number. If the pet is registered with us, we help you reach the owner, and our live agent line at 1-800-AID-PETS is available around the clock.
How a microchip lookup works
Every pet microchip carries a unique number, usually 15 digits, that a vet, shelter, or animal control officer reads with a scanner. The number on its own says nothing about the owner. It has to be matched against a registry, which is what a lookup does: you enter the number, and the registry that holds the record responds with a way to reach the owner.
The United Pet Club registry accepts chips from any manufacturer and participates in the AAHA universal pet microchip lookup, the tool shelters and clinics check first when a stray comes in. If a number is not in our registry, the universal lookup shows which registry does hold it, so the trail does not go cold.
If you are a pet owner reading this: a lookup only works if your chip is registered and your contact details are current. Register your pet's microchip free, or check what the free lifetime plan includes.
What to do when you find a lost dog or cat
1
Check the collar first
A tag with a phone number is the fastest way home. If there is a QR or code tag, scan it with your phone camera; it opens the pet's registry profile.
2
Get the pet scanned
Any vet clinic, shelter, or animal control office can scan for a microchip, and most will do it free for a found pet. The scan takes seconds and shows the chip number.
3
Run the number through a lookup
Enter the chip number in the United Pet Club pet recovery lookup, or in the AAHA universal lookup if you want to check every participating registry at once.
4
Reach the owner or hand off
If the number matches a registered pet, the registry connects you with the owner. If not, the vet or shelter can take it from there under your local found-animal rules.
What the recovery lookup covers
Microchip numbers
Any brand of ISO microchip, not just chips sold by United Pet Club.
Tag and code lookups
The code printed on a United Pet Club QR tag can be typed in by hand if scanning is not an option.
Tattoo and passport numbers
Older identification methods still lead home: the lookup accepts tattoo and pet passport numbers too.
Free, 24/7
The lookup costs nothing and never closes, and the 1-800-AID-PETS live agent line can help coordinate a reunion any time.
Microchip lookup questions
How do I look up a pet's microchip number?
Have the pet scanned at any vet or shelter to get the chip number, then enter it in United Pet Club's free pet recovery lookup, available from the Recover a Pet button on every page of unitedpetclub.com. The AAHA universal microchip lookup is another route; it checks participating registries, including ours, in one search.
Is a microchip lookup free?
Yes. Searching the United Pet Club registry costs nothing, and there is no account required to look up a found pet.
Can I find an owner's home address from a chip number?
No. A lookup does not hand out personal details. It connects you with the registry, which reaches the owner through the contact information on file, so the owner stays in control of what is shared.
What if the chip number is not registered anywhere?
It happens more than you would expect: the chip was implanted but never registered. A vet or shelter can sometimes trace the manufacturer from the number's prefix and contact the clinic that bought the chip. This is also the best argument for registering your own pet's chip today.
What is the AAHA universal pet microchip lookup?
A free tool from the American Animal Hospital Association that checks many registries at once and reports which ones hold a record for a chip number. United Pet Club participates in it, which is one reason shelters can find our records quickly.
Make sure a lookup leads back to you
The finder's side of this page only works if the owner's side is done. Register your pet's microchip free, and keep your contact details current.
