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.

Elke dierenkliniek heeft een eigen UBN nummer gekregen. Dit nummer kunt u opvragen bij RVO en is nodig voor het bestellen van paspoorten en chips.

Dogs born or imported after April 1st 2013 must be registered in a government-approved database. Also, all changes in the dog’s details must be recorded. As a database provider, we must offer the owner the opportunity to meet this obligation, without using the database’s function (reuniting a missing animal with its owner). If you indicate that the registration of a dog is not to be used for reunification, we cannot release any details of the owner once a missing dog has been found. In that case, the dog goes to an animal shelter and, after a fixed period, becomes eligible for relocation. Seeing that the databases mainly exist to reunite missing animals with their owners, we advise you to DO make use of the reunification possibility. Therefore, it is preferred to leave the tick box alone. Only use it if a new owner insists on not using the option and is well aware of the possible consequences. If an owner does not want to show his/her details in the public section, it is better to use the option "reporting institution only". In that case, a found animal can still be traced back to an owner through you or us. Also, try to explain to the owner that "public" means that his/her details can only be retrieved by someone who knows the 15-digit microchip number. We advise people to always choose for a full release of details (reporting institution + owner’s details) for a fast and simple reunification of a missing animal with its owner.

The ISO-standards 11784/85 together form the standard for electronic animal identification. ISO 11784 determines the number structure (15-digits, the first 3 are a manufacturer’s or country code).

ISO 11785 describes the technical concept of the microchips. All chips sold by PetBase/Micpoint BV comply with these standards.

If you entered the wrong chip number, it cannot be changed just like that. The easiest solution is to fill in the contact form, including the microchip number and registration number, and clearly state the wrong and correct number. We will then take care of a correct registration.

In the United States, among others, the FDX-A microchip number is often used. An FDX-A chip number has a 10-digit code and mostly consists of 9 numbers and 1 letter. In Europe, the FDX-B chip numbers are always used for pets. These chip numbers are composed in a fixed manner – they always consist of 15 numbers. The first three numbers are either a manufacturer’s or country code. Manufacturer’s codes always begin with a 9, e.g. 945 for FiveStar transponders. A transponder number that begins with 999 is a test number which doesn’t have to be unique.
If the number starts with a country code, the numbers in 4th, 5th and 6th position also have a fixed meaning. A number 0 on the 4th position means it is a test number and doesn’t have to be unique.
A number beginning with 5281400 is a number from the Dutch ‘Raad van Beheer’ (Management Board). When there is a 2 in the 4th position, the numbers in 5th and 6th position are a derivative of the manufacturer’s code. This can be calculated by deducing the derivative number from 991. So, a number that starts with 5282460 is a chip number from the Netherlands (528) with a manufacturer code (2) of 945 (991 - 46 = 945). The last 8 numbers make the number unique. They are serial numbers which are not packaged in sequence. A box of chip numbers therefore seldom contains two sequential numbers.
