Verification Status

We don't yet have per-talkgroup data for Plainfield Police from the RadioReference API. The encryption scope and type above come from the RadioReference Wiki, which is community-maintained rather than independently confirmed channel-by-channel. Our automated matching put this at low confidence (60%) based on how closely the wiki listing matches this agency's name and county.

If you monitor Plainfield Police 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.

Union County Context

Union County is a mixed picture: 6 of 12 agencies we track here are fully encrypted (50%), which means some neighboring departments are still audible on a scanner.

What This Means

Our records list every channel this agency runs as encrypted, including day-to-day dispatch. That listing hasn't been verified against live talkgroup data, so confirm it at RadioReference before relying on it.

Frequently Asked Questions

Is Plainfield Police radio encrypted?

Our database lists Plainfield Police as using P25 ADP encryption, though this listing is unverified. Our records list every channel this agency runs as encrypted, including day-to-day dispatch. That listing hasn't been verified against live talkgroup data, so confirm it at RadioReference before relying on it.

Can I listen to Plainfield Police on a police scanner?

Likely not, if the listing is accurate: our database lists Plainfield Police as fully encrypted using P25 ADP, which no consumer scanner can decode. The listing is unverified — check the live RadioReference database for current status.

Why do agencies like Plainfield Police encrypt their radio?

The standard justification nationwide is officer safety and operational security, regardless of whether a documented local incident ever required it. The tradeoff that follows is consistent too: public oversight drops, and reporters lose the ability to track police department response as it happens.

Can Union County reverse the encryption decision?

It can. The radios support open and encrypted operation equally well, so this is a configuration and a policy, not a constraint — and policies set by Union County officials are policies those officials can revisit when constituents press for it.

What can I do about Plainfield Police encryption?

Put the question to whoever signs off on Plainfield Police's radio budget: why full encryption rather than a delayed feed or tactical-only channels? File for the recordings and the decision documents alongside it, and link up with neighbours and local reporters in Union County so the ask arrives as a group rather than a one-off.
