How do I register a pet's microchip, step by step?
Registering a microchip is a short administrative process, not a medical one — it's usually done entirely online, after the chip has already been implanted, and takes most people under ten minutes once they have the chip's ID number ready. The chip on its own is not enough to make the link between you and your pet: for a microchip to do its job, it has to be registered with a registry.[1]
-
Find your chip's ID number
It's usually printed on paperwork given at implantation — an ID card that came with the microchip, a vet discharge summary, or an adoption packet. If you don't have paperwork, a vet or shelter can scan the pet and read the number back to you for free in seconds.
-
Choose a registry
There is no single universal microchip database — each registry keeps its own records, so which one you pick determines where a vet or shelter finds your details.[1] See how to choose a registry.
-
Create an account
Most registries require an account tied to your email, so the record can be edited later without starting over.
-
Enter your contact information and your pet's description
Expect to provide your name, phone number, email, and mailing address, plus your pet's species, breed, color, sex, and approximate age or date of birth — see what information belongs on a chip record for the full picture. Check every field before you submit; a registry stores only what you type into it, and the phone number matters most.[1]

Pay any registration fee
Complete the registration including paying any registration fee.
-
Confirm the details are saved
Most registries send a confirmation email or generate a certificate once registration is complete — worth saving as a record that it went through.
Getting these details right is the whole point. In a study of 7,704 microchipped animals entering 53 U.S. shelters, staff couldn't reach an owner for 876 of them — and the single biggest reason was an incorrect or disconnected phone number on the registry record (35.4%). Another 17.2% had a chip still registered to a breeder, shelter, or veterinary clinic rather than to the owner.[2]
What if I don't know my chip's ID number?
Any vet, shelter, or animal-control office should have a universal scanner and read the number for free, typically without an appointment. This is also the fastest way to find out if a chip is already registered somewhere, since a lookup starts from the number.
Just be sure to triple-check the number when you write it down, because typo errors are very common. Chips built to the international ISO standards carry a 15-digit code, and a single wrong digit points at a completely different record.[3]
What information will I need?
At minimum: your name, a phone number, an email address, and your mailing address, plus a basic description of the pet. Some registries also ask for an emergency contact or a vet clinic's contact information as optional extras. See what information belongs on a chip record for the full breakdown of what's typically required versus optional.
How long does registration take?
For most owners, a few minutes — the process is a short form, not a lengthy application. The only real bottleneck is not having the chip's ID number on hand, which is why it's worth locating it before starting.
