When a pet owner hears about the National Companion Animal Registry (NCAR), their first thought is often that it’s yet another mandatory government platform. In reality, its purpose runs much deeper. The NCAR is Greece’s official national database for both owned and stray dogs and cats — a centralized, digital system designed to improve animal welfare, strengthen responsible pet ownership, and support lost-pet recovery.
What Is the National Companion Animal Registry?
Established under Law 4830/2021, the NCAR serves three core functions: maintaining a unified registry of companion animals; enabling rapid identification of owners when pets go missing; and supporting accountability throughout an animal’s life. It records key events — such as changes in ownership, reported loss, or death — creating a lifelong digital dossier for each registered animal.
How Registration Actually Works
A common misconception is that owners must personally register their pets on pet.gov.gr. That’s not the case. Initial registration is performed exclusively by a certified veterinarian. Only licensed vets can implant the required microchip, verify the animal’s identity, and enter all mandatory data into the NCAR. Once this step is completed, the animal’s official electronic file is created — and only then does the owner gain access to related services.
So What Is pet.gov.gr?
pet.gov.gr is Greece’s official digital gateway for pet owners — not a registration portal, but a secure access point. Using their personal Taxisnet credentials, owners log in to view their registered pets, access the digital health booklet, confirm identification details, and use online services like reporting a lost pet or transferring ownership. In short: the vet creates the record; pet.gov.gr lets you manage it.
The First Step Every Owner Should Take
Before logging into pet.gov.gr or searching for digital services, confirm two things: your dog or cat has been implanted with a compliant microchip, and that a certified veterinarian has fully registered the animal in the NCAR. The microchip alone is meaningless without proper digital enrollment — a detail many owners overlook, yet one that makes all the difference in reuniting lost pets with their families.
