Frequently Asked Questions

Is United States Postal Service radio encrypted?

Yes — United States Postal Service's radio system runs on P25 AES-256 encryption. Everything this agency transmits is encrypted, dispatch included. For anyone outside the department — residents, reporters, neighbouring responders — the channel is simply silent.

Can I listen to United States Postal Service on a police scanner?

No. United States Postal Service has fully encrypted their radio communications using P25 AES-256. No consumer scanner can decode encrypted transmissions.

Why did United States Postal Service encrypt their radio?

Officer safety and operational security are the reasons agencies give. What rarely comes with that explanation is Parishwide 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 Parishwide County reverse the encryption decision?

Yes, and some departments already have. Because encryption here is a choice rather than a technical necessity, the path back runs through the same people who chose it: budget hearings, records requests, and residents who keep asking in public.

What can I do about United States Postal Service encryption?

Contact the officials who oversee United States Postal Service's budget directly and ask why full encryption was chosen over partial alternatives. Pair that with a FOIA request for recordings and policy records, and look for an existing coalition in Parishwide County, or start one, since agencies respond differently to organized, sustained pressure than to individual complaints.
