The Petlink ACO app is for Animal Professionals (ACOs, Shelter or Rescue teams) in North America to use in the field. When Animal Professionals find a lost pet, they can use Petlink ACO on their phones to look up owner details via the pet’s microchip number and submit a found pet report to PetLink. We will contact the owner to let them know their pet has been found and set up reunification. You can put the microchip number into Petlink ACO on your phone by keypad or speak the number in. You can also use the camera to capture the microchip number from the LCD display of a microchip reader. Using the camera makes it much faster to transfer the 9-, 10- or 15-microchip number from the chip reader to the search function of Petlink ACO. It also reduces typing errors. Petlink ACO will search for owner details first in PetLink, then in PetLink’s Backtrack system and finally in the AAHA Pet microchip look-up tool. Petlink ACO will help save the lives of lost animals. The quicker a pet is returned to its owner, the greater their chance of survival. Petlink ACO allows Animal Professionals in North America to contact the owners of lost pets as soon as they have read the pet’s microchip number. There is no need to call PetLink, no need to use a computer to look up details. Animal Professionals can use Petlink ACO to submit a found pet report in 4 easy clicks. We will then notify owners via SMS, phone and email, that their pet has been found and organize reunification. When an Animal Professional finds a lost pet and that pet is registered with PetLink, then Petlink ACO will show a photo of the pet, if available, to confirm identification. Petlink ACO will also show medical details, if available, for the pet, for example if a dog is diabetic and needs regular insulin, this information will be clearly shown. This will be beneficial for the health of all lost pets. PetLink - the industry standard in pet microchips for over 30 years. PetLink is an industry leader in pet microchips, pet identification and reunification, creating a lifelong link between people and pets. PetLink helps Animal Control Officers, Shelter staff and rescues return lost pets to their families and prepare adopted pets for their new homes. For the last 30 years PetLink has been making it quicker and easier for people to microchip their pets. Instead of complicated processes and annual charges, we provide lifetime support to pet parents for a simple one-time registration.
