Compulsory identification and registration for dogs (I&R)

Since April 1, 2013, it is mandatory in the Netherlands to chip and register all dogs in a database designated by the government, such as PetBase. These rules have been tightened since 1-11-2021. This identification and registration (I&R) is mandatory for all dogs born in the Netherlands or imported and now also has an EU Animal Passport obligation. Dogs must be chipped within seven weeks of birth and registration must be completed within eight weeks of birth. 

Dogs imported to the Netherlands need to be registered within two weeks after arrival. Only dogs who have already been microchipped, combined with an official pet passport, are allowed to enter the country – save for dogs staying in the Netherlands for no longer than three months.

Do not buy a Dog that is not registered and does not have an official EU pet passport!

The owner of a dog must accept these obligations and is also responsible for them. A breeder or someone who imports dogs is the first Dutch owner and must register the animal in his/her name. Does the dog change owners? Then this can easily be changed online in PetBase via the unique Mijn PetBase account.

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.

You can do your registrations via our website, but also directly from more and more management software such as Animana, Vetware, DAISY and VetBase. After registration, the data can be called up directly via our website.

In the United States, among others, the FDX-A chip number is often used. An FDX-A chip number has a code of 10 characters long and usually consists of 9 digits and 1 letter. In Europe, FDX-B chip numbers are always used for pets. These chip numbers are built up in a fixed way. They always consist of 15 digits. The first three digits are either a manufacturer number or a country code. Manufacturer numbers always start with a 9, for example 945 for FiveStar transponders.

If the chip number has been entered incorrectly, it cannot be changed just like that. The registration must be withdrawn via the trash can in the registration. once the registration has been withdrawn, a new registration can be made.
