Microchipping a dog or cat typically costs $25 to $60 at a private vet, with a national average around $48. Shelters and low-cost clinics often do it for $10 to $25, and some community events offer it free. The price is the same for all pets and sizes, since the chip and the procedure are identical.

But that's just the cost to implant the chip. Some places include registration with the procedure, and some leave it entirely to you. Registration is a separate step, often a separate cost, and it's the step that actually connects the chip to your contact information. It's also the step most commonly skipped, and a chip that was never registered can't bring your pet home.

This guide covers what the procedure costs at different places, what registration costs on top, and how to check whether your pet's chip is actually registered.

The registration gap: the part many pet owners miss

A microchip stores a unique ID number and nothing else. It doesn't hold your name, phone number, or address, and it can't track your pet's location. When a shelter or vet scans a found pet, all they see is that number. They then search it to find which registry has your contact information on file. If the number isn't registered anywhere, the search goes nowhere. Learn more about how pet microchips work.

The problem is that implantation and registration are two different steps, and who handles the second one varies. Some vets and shelters register the chip for you before you leave. Others hand you a pamphlet with the information to register the microchip yourself. Plenty of pet owners walk out believing their pet is protected when the chip is really just an unregistered number.

Checking takes about a minute. Enter your pet's chip number into the AAHA Universal Pet Microchip Lookup Tool, the same tool shelters and vets use nationwide. It will show you which registry, if any, holds a record for that number. If nothing comes up, you'll want to register it. If the record points to a previous owner or the shelter you adopted from, you'll want to contact them to transfer it to your name. We wrote a full guide on how the AAHA lookup tool works, and if you need to fix your registration, here's our step-by-step guide to registering your pet's microchip.

What the procedure costs, by provider

Private vet: $25 to $60 for the chip and implantation. One important thing to budget for: most vets charge an office visit fee on top of the procedure, and the average vet visit in the U.S. runs about $50 to $80. If your pet is due for a checkup anyway, have the chip done during that visit so you're not paying for a second appointment. Many vets will also implant the chip during a spay or neuter while your pet is already under, which skips the discomfort entirely.

Shelter or humane society: $10 to $25, sometimes free. Many shelters run low-cost microchip clinics, and pets adopted from shelters usually come home already chipped. If yours did, you don't need to buy a chip. You just need to confirm the existing one is registered to you and not the shelter. Here's what to do about your pet's microchip after adoption.

Pet store vaccine clinics: $15 to $25. Petco, PetSmart, and mobile vaccine clinics often offer microchipping as a walk-in add-on with no exam fee, which makes them one of the cheapest ways to get it done.

Community events: free. Local animal welfare departments and rescues periodically run free microchipping events. Check your city or county animal services page.

The procedure itself is quick no matter where you go. The chip is about the size of a grain of rice and goes in with a needle slightly larger than a vaccine needle. There's no anesthesia or recovery time, and the chip lasts your pet's entire life without any maintenance.

What registration costs

Registry pricing generally falls into two camps. Some registries charge a one-time lifetime fee, typically in the $20 to $30 range, and your pet stays registered forever with free contact updates. Others use subscription pricing or bundle registration into larger protection plans, where keeping full features active can run $20 to $30 every year, or over $100 upfront. Over the 12 or more years most pets live, that difference becomes significant.

Pawbase is $24.99 for lifetime registration, which supports all microchip brands and includes free contact updates. For a full feature-by-feature look at how the major registries compare, see our breakdown of the best pet microchip registries in 2026.

Is it worth it?

The American Veterinary Medical Association estimates that 10 million pets go missing in the U.S. every year, and about 1 in 3 pets will get lost at some point in their lifetime. Even careful owners deal with an open gate, a spooked cat during a move, or a dog that bolts at fireworks. Collars and tags help, but they can slip off or be removed. A microchip can't.

The AVMA's data backs this up. Microchipped dogs make it back to their owners more than twice as often as dogs without chips, and the difference for cats is even bigger. For a nominal cost, your pet is connected to you for life.

In summary

Expect to pay $25 to $60 for the chip at a vet plus an office visit fee, or less at a shelter, pet store clinic, or community event. Then make sure registration actually happened, because implanting the chip and registering it are two different steps, and the second one is often left to you. Run your pet's chip number through the AAHA lookup tool today, and if nothing comes up, register it. Choose a registry with a one-time lifetime fee so the cost ends there, and keep your contact information current.
