UBN number verification: what is it for?

A UBN check is a handy tool that allows you to check whether a UBN number (Unique Company Number) is valid. A UBN is used to identify companies and locations where animals are kept. With a UBN check you can quickly verify whether a UBN number is valid and thus obtain important information about the relevant location or owner. This helps to keep correct records, to ensure animal welfare and to comply with laws and regulations in the animal industry.

Best of all, you no longer need to switch applications, as everything is available within our all-in-one portal.

These organisations went before you:


Previously, corporate breeders needed to be registered, but now also the non-commercial breeders.. This is done through the website of the RVO (Rijksdienst voor Ondernemend Nederland). RVO then gives the breeder a UBN (Unique Company Number) even though you are not a company.

Every professional breeder of dogs in the Netherlands has received (or can apply for) a UBN from RVO. With this number, you can register puppies for the first time. After fitting the chip by a veterinarian or recognised chipper, the animals can be registered directly in PetBase. The legally required notifications to RVO can then be made immediately.

A UBN number is required for dogs to issue an official EU pet passport in the Netherlands.
