How much does it cost to microchip a dog or cat?

Typically $25-$75 at a full-service vet clinic, $15-$35 at shelters and low-cost clinics, and sometimes free at community events. It's a one-time cost — the chip lasts for the pet's lifetime. Ask about bundling it with a spay/neuter appointment, which some clinics discount.

Does microchipping hurt my pet?

The chip is injected with a needle, similar to a routine vaccination, and the procedure takes seconds. Most pets react about as much as they do to a shot. No anesthesia is required, though it's often placed while pets are already anesthetized for spay/neuter surgery.

Do I need to pay to register the microchip?

Basic lifetime registration is typically free with major microchip registries. Some registries sell premium add-ons (lost-pet alert networks and similar), but the free basic registration — your name and phone number linked to the chip number — is the essential part. Be wary of any provider implying registration requires payment.

Is a microchip a GPS tracker?

No. A microchip doesn't show your pet's location — it's a passive ID chip that only reveals its number when scanned with a microchip reader. It identifies your pet when a shelter or vet scans them. Keep a collar with ID tags as well, since tags work without any special equipment.

My pet is microchipped but I moved. What do I do?

Update your contact information with the chip's registry immediately — an outdated phone number is one of the most common reasons microchipped pets can't be reunited with owners. If you've lost track of which registry holds the chip, use the free AAHA Universal Pet Microchip Lookup tool with the chip number.

Where can I get my pet microchipped for free?

Free microchipping events are periodically offered by municipal animal services, humane societies, SPCAs, and nonprofit outreach programs — usually announced on their social media pages. Shelters also commonly include microchipping in adoption fees. Low-cost options ($15-$35) are available year-round at most humane society clinics.

Pet Microchipping Costs: What You'll Typically Pay

A microchip is a tiny ID chip, about the size of a grain of rice, placed under your pet's skin — and it's one of the cheapest permanent safeguards you can buy. Here's what it typically costs.

Informational only — not veterinary advice. This guide covers costs and options only. It does not diagnose, recommend treatment, or rank veterinarians, and it is not a substitute for a licensed veterinarian. Talk to your vet about your pet’s specific needs.

If your pet ever gets lost, a microchip is the difference between a shelter being able to identify them in seconds and your pet becoming one of the thousands of unclaimed strays. Unlike a collar tag, it can't fall off or be removed. And unlike most pet expenses, it's a one-time cost — typically less than a bag of premium dog food.

This guide covers what microchipping typically costs at different providers, the often-overlooked registration step, and where to find free or discounted chipping events.

The short answer: Microchipping typically costs $25–$75 at a veterinary clinic, $15–$35 at shelters and low-cost clinics, and is sometimes free at community events. The chip itself lasts for the pet's lifetime — but you must register it with your contact info, which is free with most major registries.

Typical microchip costs by provider

Full-service vet clinic: typically $40–$75, often done during a regular exam or spay/neuter appointment (ask about bundling — some clinics discount the chip when placed during surgery)
Low-cost and nonprofit clinics: typically $15–$35 — many humane societies offer walk-in microchipping at these prices
Shelters (at adoption): often included in the adoption fee, or $15–$30 if done separately
Vaccine clinic pop-ups: typically $20–$35 alongside low-cost vaccines
Free community events: periodically offered by shelters, municipal animal services, and nonprofits — usually announced on social media

Because it's a quick procedure — the chip is injected with a needle, similar to a vaccination, and takes seconds — many providers offer it as an add-on service. If your pet is already going under anesthesia for a spay or neuter, ask about adding the chip during the same visit.

The registration step everyone forgets

Here's the critical part: the microchip is useless if it's not registered with your current contact information. The chip itself only contains an ID number. When a shelter or vet scans it, they look up that number in a registry database to find the owner. Studies of shelter outcomes have consistently found that a large share of microchipped stray pets can't be reunited with owners because the chip was never registered or the contact info is outdated.

What to do:

Register immediately after chipping — don't assume the clinic did it for you. Ask explicitly: "Is the chip registered, or do I need to do it?"
Registration is typically free with major registries for the basic lifetime listing. Some registries offer paid premium tiers (lost-pet alerts, etc.) — the free basic registration is what matters.
Update your info when it changes. New phone number, new address — update the registry the same week. An outdated number is nearly as bad as no registration.
Check the registration annually. Ask your vet to scan the chip at a yearly visit to confirm it still reads, and verify your contact details are current in the registry.
Use the free universal lookup. The AAHA Universal Pet Microchip Lookup (a free online tool) tells you which registry holds a given chip number — useful if you've lost track of where you registered.

Important: A microchip is not a GPS tracker. It doesn't show your pet's location — it only identifies them when someone with a scanner checks. Keep a collar with ID tags too; tags get a lost pet home without any special equipment.

What about the different chip frequencies?

You may hear about 125 kHz vs. 134.2 kHz (ISO standard) chips. The practical takeaway is simple: most modern shelters and vet clinics use universal scanners that read both. If your pet was chipped years ago with an older frequency, it's still worth keeping the registration current — but if you're chipping a new pet today, the provider will use whatever is current standard. This isn't something you need to shop for; just make sure the chip gets registered.

Finding free or discounted microchipping

Humane societies and SPCAs — many offer low-cost microchipping ($15–$30) during regular hours; check our directory pages like low-cost vet clinics in Ohio or low-cost vet clinics in Arizona
Municipal animal services — city and county shelters periodically run free chipping events, sometimes tied to licensing drives
Pet store vaccine clinics — weekend pop-up clinics commonly offer microchipping alongside vaccines
Nonprofit outreach events — community pet wellness events in underserved neighborhoods often include free microchipping
At adoption — if you're adopting, ask whether the fee includes chipping and registration; it often does

Follow local shelters and humane societies on social media — free chipping events are usually announced there first and can fill up quickly.

The bottom line

Microchipping is one of the highest-value purchases in pet care: a one-time $15–$75 cost for lifetime identification. Get it done at the cheapest reputable provider available, register the chip the same day, and keep your contact info current. It takes ten minutes and it lasts as long as your pet does. While you're handling the one-time essentials, our low-cost vaccination guide covers the other affordable preventative care worth doing early.
