Your pet registered

PetBase registers the chip numbers of dogs, cats, rabbits, ferrets, horses and all other animals who can be microchipped, so that retrieved pets can be returned to their owners easily.

Webshop for vets

We offer an exclusive webshop for veterinarians where you can order - among other things - pet passports, vaccination certificates, microchips and readers under the PetBase private label.

Registering and changing details

Do you want to register your pet? This is easily and cheaply done at PetBase. You decide which information is displayed. Do not forget to update any information (for free) if you are moving house, for example.

Your information is safe with PetBase

PetBase meets all requirements regarding the latest privacy regulations. Authorized institutions are able to request your information once a pet is retrieved, depending on which information is shared by you.

Welcome to PetBase

PetBase is a government-approved database for registering microchipped dogs and other pets. Because it has been microchipped, we can reunite you and your pet once it has been found. Your vet, animal shelter or breeder can take care of the registration for you. Make sure your information is correct and do not forget to update in case of any changes, such as moving house.

Registraties in PetBase van voor 1 november 2021 hebben nog geen account. Dan heeft u nog een oude registratie en die kunnen inloggen met een chipnummer en registratienummer. Eenvoudiger is nog een Gratis account aanmaken bij en dan met het chipnummer en registratie nummer de hond of kat of andere dieren daar aan toevoegen.

Een overdrachtscode is nodig om een registratie van een huisdier over te zetten op een nieuwe eigenaar. Ook wel verhuiscode genoemd en zonder deze code is het niet mogelijk om het dier op een andere houder / eigenaar te zetten. De oude eigenaar kan deze opvragen in de portal en deze aan de nieuwe eigenaar geven. Meer informatie kunt u vinden op de PetBase support portal.


With sterilization, the animal is made infertile by tying off the oviducts. In practice however, it’s much more common to remove the ovaries – which in fact is a castration for females. Sometimes the uterus is also completely removed (in case of uteritis, for example).

If the animal was deregistered, you can easily register it again in your name (as the new owner). Follow the link and login with your microchip-/transponder number and registration number. You can find the chip number in your vaccination certificate or pet passport. It is also found, together with the registration number, on the blue PetBase form or in the confirmation e-mail. The previous owner also received an e-mail with the registration number during the deregistration.


The standard institution that shows up while retrieving a chip number, is the one that registered the microchip. This institution has the original registration form. If desired, you can choose a different institution when you have switched vets, for example. You can only choose from the existing reporting institutions, because only they have access to the registrations and are allowed to change them. So, it may happen that your (new) veterinarian can’t be selected, in which case you can leave the standard unchanged. When moving house, it is important to let us know your new details. You can also inform your previous veterinarian about the change.
