Do I have to register with the pet registry suggested by my veterinarian?

No. PetLink will accept any valid 9, 10 or 15 digit microchip.

How will I know my pet's microchip is registered?

After you complete your online registration, you will receive a confirmation email from PetLink.

If you do not receive an email confirmation, please email us at

What do I do if my pet's microchip is already registered?

Sometimes the microchip number of a pet is already registered in PetLink. This may be for a variety of reasons, including an error. Below are the most common reasons and directions for how to resolve this issue:

Verify the microchip number

Please make sure you typed your microchip number correctly.

Someone already registered your microchip number

Somebody might have registered your pet’s microchip number by accident. Alternatively, a shelter or vet might have already registered the pet on your behalf. In this case, please email us at

Why should I microchip and register my pet with PetLink?

Microchipping allows you to provide your pet with a lifetime ID number. An ISO-compliant microchip contains a unique and unalterable identification number that is recognized in most countries around the world.

Microchipping is a reliable, permanent, one time service that helps give you peace of mind for your pet’s lifetime, but it is nearly useless if the microchipped pet is not registered in a database such as PetLink. The microchip only contains an identification number; without accurate registration associated with the microchip number, a lost, microchipped animal that is scanned might not be returned to its owner.

Don’t wait! Register your pet with PetLink! The sooner, the better!

What type of registration is included with my microchip?

Your pet’s microchip has one of three registration options that your veterinarian or shelter organization chooses when they purchase Datamars Microfindr microchips. The PetLink website will let you know what type of registration type your microchip has during the registration process. Below are the three options that are available:

  • Lifetime Registration – the registration fee has been prepaid on your behalf by your vet or shelter organization. No additional registration fee is required to complete your pet’s registration online with PetLink*. Your pet is protected for life! No subsequent renewals or annual fees are required*.
  • One Year Registration – your pet’s first year of registration with PetLink has been paid in advance by your vet or shelter organization. You will be notified by email when your One Year Registration is coming to an end so that you can upgrade to Lifetime Registration to ensure your pet remains covered should he or she be lost. To complete Lifetime Registration, you will be required to pay a one-time upgrade fee. We offer significant discounts to One Year customers who are upgrading to Lifetime Registration before their One Year Registration expires. Keep an eye out for emails from PetLink! Once your upgrade is complete, your pet is protected for life! No subsequent renewals or annual fees are required*.
  • No Registration – no registration has been purchased in advance, so you’ll be asked to pay a one-time, lifetime fee of $19.99 to register your pet’s microchip with PetLink. Once this fee is paid, your pet is protected for life! No subsequent renewals or annual fees are required.

In all cases, there are no monthly or annual fees associated with your PetLink registration! For assistance, please email us at

*Please note if you call the PetLink Call Center to register your microchip over the phone, you may be subject to a $4.95 operator assistance fee

How do I upgrade from One Year to Lifetime registration?

PetLink will periodically notify you via email when your One Year Registration is due to expire. To upgrade your pet to lifetime registration, follow these steps:

  • Login to your PetLink account (input your e-mail address and password)
  • Once you are logged in, you will see the names of your pets listed on the right of your home screen.
  • If a pet’s registration is due to expire, you will see a link highlighted in red next to that pet’s name “Upgrade to lifetime registration now”. Click the link and you will be redirected to a payment screen where you can pay the one-time fee to complete your lifetime registration upgrade.
  • Once your payment has been accepted, you will receive a confirmation email; no further fees or annual renewals are needed to keep your PetLink account active.

Lost/Found Questions

What if my pet is lost and PetLink can't reach me?

PetLink asks anyone registering their pet to provide alternate contacts, which may be a relative, a friend or a veterinarian. PetLink will call/email these individuals if the owner cannot be reached.

It also is imperative that pet owners keep their contact information up-to-date in their user profile. We will make repeated attempts for up to 72 hours to contact an owner or alternate contact to make a reunification.

What should I do if my pet is lost?

Contact PetLink immediately to report your pet as lost. You can call us at 1-877-PETLINK (738-5465) or file a Lost Pet Report online.

You can also login to your PetLink account and create a Lost Pet Poster to put up in the area where your pet was last seen. As soon as your pet is found, we will immediately get in touch with you by phone and email.

I found a pet. What should I do?

Please try to keep the pet safe. If you are not comfortable keeping the animal, you may bring it to a local veterinary clinic or animal shelter. While at the veterinary clinic or animal shelter, we suggest that you ask an employee to scan the pet for a microchip.

If the pet is microchipped, please file a Found Pet Report online or call 1-877-PETLINK (738-5465). We will do our best to contact the owner as soon as possible.

Questions About Microchips

How to implant and register a microchip? (video)

What happens if the implanted microchip doesn't work?

The veterinarian or shelter organization that microchipped your pet will scan the microchip to make sure it works during the implantation procedure. In the unlikely event that the microchip stops working after it is implanted, and the microchip was manufactured by Datamars, please have your veterinarian or shelter organization contact PetLink at for assistance.

Will the microchip wear out and need to be replaced?

The microchip does not have an internal battery or power source. In fact, it’s completely passive. When a microchip reader is passed over it, the microchip receives enough power from the reader to transmit the pet’s ID number. Since there is no battery and there are no moving parts, there’s nothing to wear out or replace. The microchip will last throughout your pet’s lifetime.

Is microchipping painful for my pet?

A microchip is as small as a grain of rice, and is easily implanted under the skin of your pet. Microchip implantation is no more painful to pets than getting a flu shot is to you. Microchipping doesn’t require anesthesia and it takes only seconds

Can the microchip migrate or move around after implantation?

When properly implanted, a microchip should not migrate or move beyond an inch or so. If, for some reason, you find that your pet’s microchip has migrated from the original implant site to a different part of your pet’s body, check with your vet to ensure your pet is not in any danger.

Does a microchip work like a GPS? Why can't I get a physical location for my lost pet?

Pet microchips are not tracking devices. While there are many tracking devices available for pets, they require your pet to wear a receiver on his or her collar that must be removed and regularly recharged. What happens if your pet is lost while its GPS receiver is being charged? Also, the GPS tracking devices for pets usually only allow you to set a certain perimeter for your pet; if your pet leaves that area, no tracking data can be transmitted. The receivers, like all collars, can be torn off, chewed off or removed. Monthly service fees, just like a data plan, are also usually needed. Since there’s no battery and no moving parts in a microchip, there’s nothing to keep charged, wear out, or replace. The microchip will last your pet’s lifetime – and with PetLink, there are no monthly or annual fees – EVER.

Microchips are passive, meaning that they do not need a battery to work. The microchip is about the size of a grain of rice and is implanted under your pet’s skin – like getting an injection. Although tracking information is not available from a microchip and we cannot tell exactly where a pet is located, if found, it is standard procedure nationwide for veterinarians, animal shelters, human societies and animal control agencies to scan pets for microchips in the hopes of finding an owner’s contact information through the microchip’s online registration.

Microchipping is the only form of permanent, unalterable, unique identification that an owner can provide for a pet. Give your pet a silent voice for the times when he or she is unable to speak for themselves – and don’t forget to complete your registration in PetLink!

Can all animals be microchipped?

Microchips are about the size of a grain of rice, and are safe to be implanted in just about all species of animals. Dogs, cats, horses, birds, rabbits, ferrets, rodents, amphibians, turtles and reptiles can all be safely microchipped – any many others. For more information, visit the World Small Animal Veternary Association’swebsite, or ask your local veterinarian.

What if my pet has two microchips?

You do not need to have one of the microchips removed and they will not interfere with each other. The microchip detected by the scanner will depend on the scanner used – if it is a universal scanner, it should be able to eventually detect both microchips but it will have to be reset once it picks up the first one before it can read the second. Since it is so rare for pets to have more than one microchip, most vets and shelters don’t keep looking for a second once one microchip has been detected, so we recommend that you keep a separate registration for each of your pet’s two microchip numbers. You never know which of the microchips will be detected first – so better safe than sorry.

Microchipping your horse for an FEI Passport

Beginning Jan. 1, 2013, all American horses newly registered with the FEI must be microchipped (2012 FEI Article 1011.1.2.3). The microchip must be ISO 11784/5 compatible, and all microchip information must be entered in the horse’s passport and reported to the Unites States Equestrian Federation (USEF). This requirement applies to initial FEI registration only. Datamars Microfindr microchips comply with these regulations.

Veterinarians and Animal Professionals

How do I register my veterinary practice with PetLink?

Only licensed vets and/or members of their teams can register animal hospitals, clinics or practices with PetLink. Pet owners can list a veterinarian as an additional contact on their account if the practice does not have a PetLink profile, but only the vet can choose to complete a registration on his or her own behalf.

If you are a licensed veterinarian or member of a licensed clinic’s staff, please REGISTER YOUR VET PRACTICE.

How do I register my shelter, rescue or humane society with PetLink?

Only accredited animal shelters, rescues or humane societies can be registered as Animal Professionals with PetLink. Pet owners can list such a facility as an “Alternate Contact” on their profile, but only the facility can choose to complete a registration.

If you are staff member from an accredited Animal Professional facility, please REGISTER YOUR SHELTER.
