Why Microchipping Your Pet Is Essential and What to Expect During the Process

Microchipping stands as one of the most dependable forms of permanent pet identification available today. Unlike collars or tags that can slip off during an unexpected adventure or fade into illegibility over time, a microchip delivers lifelong identification that stays with your companion and simply can’t be lost.

The implantation process takes only moments and doesn’t require anesthesia. Yet despite its straightforward nature, lingering questions about safety and registration mean countless pets remain unchipped—or carry chips that aren’t linked to current owner information. In either scenario, the chip offers no real protection when circumstances demand it most.

Understanding how microchips function, what the procedure actually entails, and why registration represents a separate but equally vital step allows you to leverage what is otherwise a simple yet genuinely consequential preventive measure.

How pet microchips work: the technology explained

A microchip is a remarkably small electronic device—roughly the size of a grain of rice. It houses a unique identification number encoded on a tiny transponder. The chip contains no battery and no moving parts. It doesn’t emit any signal on its own and can’t track your companion’s whereabouts like a GPS device would.

When a microchip scanner passes over the implantation site, it releases a low-frequency radio wave that momentarily activates the chip. The chip then transmits its unique identification number back to the scanner, which displays the number on screen. That number is subsequently cross-referenced against a microchip registry to retrieve the owner’s contact information.

The microchip itself stores no personal details whatsoever. It contains only the identification number, while the owner’s contact information remains securely held in the registration database. This is precisely why registering the microchip—and maintaining current contact details—matters just as much as having the chip implanted in the first place.

What to expect during the microchipping appointment

Microchipping is a quick procedure performed using a needle only slightly larger than those used for routine vaccinations. The microchip arrives pre-loaded in the needle and is implanted beneath the skin, most commonly between the shoulder blades in both dogs and cats. The entire procedure takes mere seconds and typically doesn’t require sedation or anesthesia.

Most pets handle the process remarkably well, experiencing only a brief pinch comparable to a routine injection. No sutures are needed, and the injection site rarely requires aftercare beyond a quick check to confirm proper placement.

Microchipping can be completed during any routine visit and usually doesn’t need to be scheduled as a separate appointment. At Coastal Creek Animal Hospital, we commonly implant microchips during puppy and kitten vaccine visits or at annual wellness exams if the procedure hasn’t yet been completed.

The protection microchipping provides when it matters most

Collars and ID tags represent an important first line of identification, but they’re far from foolproof. A collar can slide off during an escape, and ID tags can become damaged, bent, or completely unreadable through everyday wear and exposure.

When a lost pet arrives at an animal hospital or shelter without visible identification, locating and contacting the owner becomes considerably more challenging—sometimes impossible.

A microchip addresses this vulnerability directly. Because it’s implanted beneath the skin, it can’t be removed or lost the way a collar or ID tag can.

Animal hospitals, shelters, and numerous animal control agencies routinely scan found pets for microchips, establishing a reliable pathway to connect lost animals with their families. A chipped pet therefore has a clear route home even when all external identification has disappeared.

The advantages of microchipping become most evident when a pet goes missing. A found pet with a readable microchip and current registration details can often be reunited with its owner within hours.

Without a microchip—or with outdated registration information—the reunion process can stretch much longer or may not occur at all.

Registration: the step that makes microchipping work

Implanting a microchip without completing registration provides virtually no protection. The microchip number only proves useful when it can be connected to current owner contact details held in a searchable registry.

Registration is completed by submitting the microchip number along with current owner contact information to a microchip database. Some registries charge a one-time fee, while others are free. Your care team can advise on which registries are most widely accessed in your area, as scanner compatibility and database coverage vary by region.

One of the most common reasons lost pets aren’t reunited with their families—even when they have a microchip—is because the microchip was never registered or the owner’s contact information has become outdated. The microchip number may be retrieved successfully at the shelter or hospital, but the database search returns no matching contact details or reaches a disconnected number.

That’s why registering your pet’s microchip promptly and updating your information whenever your address, phone number, or email changes is absolutely essential.

Keeping your registration information current

Registering your pet’s microchip isn’t a one-and-done task completed at implantation. Owner contact details must be updated whenever information changes. When your contact information updates or ownership transfers, updating the microchip registration should receive the same priority as updating any other essential contact record.

A microchip registered to a previous address or disconnected phone number can’t facilitate reunification, regardless of how quickly the chip number is retrieved. A microchip is only as effective as the contact information linked to it.

We recommend verifying that your registration details are current at every annual visit. If you’re unsure which registry your pet is registered with, the team at Coastal Creek Animal Hospital in Summerville, SC can assist in locating that information using the microchip number.

Common microchipping concerns addressed

Although microchipping is a routine procedure, many pet owners still have questions about how it works and whether it’s safe. Below are some of the most common misconceptions and what the evidence actually reveals.

Microchips track my pet’s location

A microchip is a passive device that doesn’t transmit any signal independently. It can’t track a pet’s location at any time. It stores only a unique identification number, which is readable only when a scanner is directly applied. Location tracking requires a GPS device, which is an entirely separate technology with different components and operating requirements.

The procedure causes significant pain

A microchip is implanted with a needle only slightly larger than a standard vaccination needle. The procedure takes a few seconds and typically doesn’t require anesthesia. Most pets tolerate the process very well, experiencing only a brief pinch comparable to a routine injection. There’s no recovery period and no restriction on activity afterward.

Microchips cause cancer

This concern originated from early animal studies, but current evidence doesn’t support a clinically relevant association between microchipping and tumor development in cats or dogs. Veterinary professionals and regulatory organizations continue to consider microchipping safe for routine use. If you have specific concerns about your pet’s individual health history, these are best discussed with your care team prior to the procedure.

One microchip is enough and requires no follow-up

The microchip itself requires no maintenance and doesn’t expire after implantation. What requires ongoing attention is the registration information. A microchip with outdated contact details can’t serve its purpose. If your phone number, address, email, or ownership information changes, you’ll need to update your registration accordingly.

Layering protection: microchips and external identification

Microchips and external identification methods work best together rather than as replacements for one another. A collar with a current ID tag allows someone who finds your pet to contact you immediately, without any specialist equipment. A microchip provides a permanent backup that remains in place if external identification has been lost.

The most effective approach to pet identification uses both. A visible tag supports rapid reunification in everyday situations. A microchip provides a reliable secondary layer of identification when the collar is absent.

Some pet owners also choose to use GPS tracking collars, which allow them to monitor their pet’s location in real time. These devices require regular charging and an active cellular subscription. While GPS trackers can be a valuable addition, they don’t replace microchipping. Unlike a GPS device, a microchip functions without power or signal and requires no ongoing maintenance beyond keeping registration details current.

What to do if your microchipped pet goes missing

If your microchipped pet goes missing, contact your microchip registry promptly to confirm that your contact details are current and to report your pet as missing if that functionality is available through your registry. Notify local animal hospitals, animal control agencies, and animal shelters directly and provide the microchip number so that if a matching lost pet is brought in, it can be scanned for that specific number.

If you’ve found an animal and can’t locate an owner, bring the animal to an animal hospital or shelter to be scanned. Once a microchip number is identified, the appropriate registry can be contacted to help locate and contact the registered owner. This process is one we carry out as a matter of routine at Coastal Creek Animal Hospital, and we’re always willing to scan a found animal whether or not the pet is a patient of our practice.

A simple step with lasting impact

Microchipping is one of the most cost-effective preventive measures available to pet owners. The procedure is quick and the microchip is permanent. When paired with current registration, protection is substantially greater than any form of pet identification that can be lost or removed.

The most common reason microchipping fails to reunite pets with their families is the lack of microchip registration, or outdated information. Ensuring the microchip is registered and that details remain current is where the real protective value lies.

If you’re in Summerville, SC, our team at Coastal Creek Animal Hospital can microchip your pet at a routine visit, confirm whether an existing chip is readable and correctly registered, and help you verify or update your contact details on the relevant registry.

Frequently asked questions

FAQ 1: Does microchipping hurt my pet?

The microchip is implanted using a needle slightly larger than a standard vaccination needle. The procedure takes only a few seconds and doesn’t commonly require sedation or anesthesia. Most pets tolerate it well, and the experience is broadly comparable to a routine injection. There’s no recovery period and no activity restriction required afterward. If you have concerns about how your individual pet may respond, particularly if they’re anxious during medical procedures, discuss this with your care team before the appointment.

FAQ 2: Do I need to do anything after my pet is microchipped?

Yes. Once the microchip is implanted, registration must be completed separately by submitting the microchip number and your contact details to a microchip database. Without this step, the chip number can’t be connected to an owner if the animal is found. You should also ensure your information is updated whenever your contact details change. We recommend reviewing this at each annual visit as a routine part of preventive care.

FAQ 3: Is my pet’s microchip compatible with all scanners?

Most animal hospitals, animal control agencies, and animal shelters use universal or forward-reading scanners that can detect the vast majority of pet microchips. However, scanner compatibility isn’t guaranteed across all devices, and some older chips or regional variations may not be detected by every scanner type. If you’re traveling internationally with your pet, check the microchip frequency requirements of your destination country, as some regions have specific standards that must be met for entry. Your care team can advise on whether your pet’s microchip meets the requirements for your intended travel.
