Lancaster FAQ
Where do I update my pet's microchip information?
Through the chip's manufacturer registry, plus DACC's licensing system. After moves, phone changes, or ownership transfers, update both promptly so DACC can reunite a lost pet quickly.
Are rescues and breeders covered?
Yes. Any organization or person releasing dogs or cats in DACC jurisdictions must implant a microchip and provide registration to the recipient under Title 10.20.355.
Los Angeles FAQ
Does my pet have to be chipped if I never adopted from a shelter?
Yes. LAMC §53.15.3 applies to every dog and cat over four months living in Los Angeles, regardless of where they came from. Most veterinarians and Animal Services clinics implant chips inexpensively.
What happens if my chip information is out of date?
Animal Services cannot reunite you with a lost pet. Update your chip registry immediately after moving, changing phone numbers, or rehoming the animal to avoid impound fees and possible citations.
