Corona, CA Animal Ordinances: Microchipping (2026)

052(A) makes microchipping mandatory in a narrow circumstance: all dogs and cats adopted from the city's animal shelter must be implanted by the city with an identifying microchip at the owner's expense, and, with one exception, the same is true for dogs and cats redeemed from the shelter. Subsection (B) makes clear that microchipping is otherwise voluntary: all other dogs and cats whose owners live in the city are encouraged to be implanted once they reach eight weeks of age, unless a California licensed veterinarian advises against it for that animal.

Subsection (C) lists exemptions from even the mandatory shelter rule, including animals with a documented high risk of serious injury from implantation, animals whose athletic ability or performance would be impaired, animals kenneled or trained in Corona but owned by a non-resident who follows their home jurisdiction's rules, and animals belonging to non-residents who are only passing through, sojourning for up to 30 days, or in town for a show. 040. 058 encourages (but does not mandate) reporting a microchip number when selling, trading, or adopting out a chipped dog or cat over eight weeks old.
