A pet microchip is a subcutaneous RFID tag read by scanners as a unique number, with no GPS function; recovery depends on matching that number to registry records.
After implanting, complete registry enrollment and keep phone and address current, because an unregistered chip is a key with no lock on file.
If lost, flag the registry immediately, circulate photos, and contact nearby clinics and shelters, since a finder scanning the chip is the most common reunion path.
Update details after moves or number changes, and have the clinic scan at annual exams to confirm the chip's position and readability.
