Riverside County uses zones for emergency notices
Riverside County's Know Your Zone and Alert RivCo pages help residents look up zones and receive local public safety notifications for the addresses they care about.
Riverside County is big enough that an emergency notice can be about one part of the county while life feels normal somewhere else. The zone lookup keeps the message tied to the right place.
Know Your Zone lets people enter an address and find the zone used by public safety officials when action is needed, such as an evacuation or shelter-in-place notice. Alert RivCo is the sign-up path for local emergency notifications to residents and businesses.
Save the zones for the places that matter: home, work, school, a relative’s house, a ranch, a regular trail area, or a business site. Riverside County has desert communities, mountain edges, valleys, washes, freeways, and fast-growing neighborhoods. A zone number keeps a message tied to the right place instead of a vague part of the county.
