Chicago FAQ
Is microchipping required for my pet?
Not for privately owned animals. Only CACC adopters and reclaimed-impound owners must accept a chip under MCC 7-12-310. Most vets recommend it because tags fall off and chips greatly improve return-to-owner rates.
How do I update chip registration?
Contact your chip manufacturer (HomeAgain, AKC Reunite, etc.) or use the AAHA Universal Lookup to find your registry. Update address and phone whenever you move; CACC matches numbers against current contact info.
Orland Park FAQ
Where do I update my pet's microchip information?
Through the chip manufacturer's registry plus any local license database. After moves, phone changes, or ownership transfers, update both promptly so CCDARC can reunite a lost pet quickly with the right owner.
Is microchipping required for all Cook County pets?
Not universally yet. CCDARC requires it for shelter adoptions and strongly encourages it at licensing. Many Cook suburbs and Chicago Animal Care and Control match the rule, so it functions as the county baseline.
