Verification Status
We do have per-talkgroup data for San Mateo County Sheriff from the RadioReference API, and used it to set the encryption scope shown above — but no additional human-reviewed source (a live feed check or a dated news account) has been recorded for this record, so treat it as a data-quality correction rather than an independently confirmed verification. Check the live RadioReference database directly for current status.
If you monitor San Mateo County Sheriff directly or have more current information, the fastest way to fix this is to update the RadioReference Wiki entry — our data pulls from there and from the RadioReference API on a regular refresh cycle.

This agency is listed as encrypting some communications while leaving others open. The per-channel breakdown is unverified — check RadioReference for current status.

Why do agencies like San Mateo County Sheriff encrypt their radio?
Officer safety and operational security are the reasons agencies give. What rarely comes with that explanation is San Mateo County-specific evidence that open communications ever caused a problem, while the loss of public oversight and the friction with still-unencrypted neighboring agencies are both immediate and real.
Can San Mateo County reverse the encryption decision?
Yes. Encryption is a policy choice made by department leadership or elected officials, not a technical requirement, so it can be reversed the same way. Public pressure, city council advocacy, and organized local coalitions have reversed encryption decisions elsewhere.
What can I do about San Mateo County Sheriff encryption?
Ask for the paperwork first — the policy that authorised encryption for San Mateo County Sheriff, and the recordings themselves — because a specific request is harder to wave away than a general complaint. Then take what you learn to a council meeting, and bring others from San Mateo County with you.
