petkey distributes the most universal type of chip used throughout the world. The ISO Conformant Full Duplex transponder (implantable microchip) is recognized by the Animal and Plant Health Inspection Service (APHIS), the agency of the United States Department of Agriculture (USDA) responsible for protecting animal health, animal welfare, and plant health. The ISO chip has international acceptance, being common in many countries including those of Europe since the late 1990s, and now widely adopted in Canada and the U.S. It is one of two chip protocol types (along with the "Half Duplex" type sometimes used in farm and ranch animals) which conform to International Organization for Standardization, or ISO, standards 11784 and 11785.

Chips come ready to inject. There are no minimum box orders. Universal Scanners are also available.

petkey and other recovery services have all worked together with AAHA to develop a Universal Pet Microchip Look Up Tool to make it easier to identify the correct registry without making multiple phone calls. If you have a found pet but are not able to determine the registry via this online tool call helpmefindMYPET and they will do all of the tracking possible to help reunite the pet with their family for FREE.
