Kansas City Metro - Metropolitan Area Regional Radio System (MARRS)/MARRS RID Ranges

From The RadioReference Wiki

Every radio on the MARRS system has a unique Radio ID (RID). It is broadcast with every transmission that radio makes, and many scanners are able to decode and display it. There are some patterns to the RIDs which might be useful to know when monitoring MARRS.

The RID is usually reported as a number of up to 7 digits. The first four digits seem to identify a particular city, agency, or function, and the last three digits are individual radios in that block.

Some large agencies, like the Kansas City, Missouri police, occupy several blocks of 1000 RIDs. Some smaller agencies, like Central Jackson County Fire and Lake City Ammunition Plant Fire/EMT, share a single block.

The main way this may be useful is that when an RID you haven't seen before talks, you can guess at which agency the user is probably with, even if they don't announce it. Sometimes this is handy on interagency talkgroups like Regional Common 3, everybody's favorite car-chase channel.

If you don't want to look through the whole list, here are some rules of thumb that usually work:

If the RID is 4 digits or fewer, it's something in Independence, Missouri.

If the RID is 7 digits and begins with 3, it's probably on the Kansas side

If the RID is 7 digits and begins with 4, it's probably on the Missouri side.

The only notable place the "3/4" rules fall down is with 3032 and 3033, which are used by ambulances on both sides of the state line.

This is based on monitoring from late 2018 to spring 2022. At the time this article was first created (mid-January 2021), some agencies in MARRS were reprogramming their radios, in preparation for moving to P25 Phase II. This may cause the radio ID ranges below to change, possibly substantially!

The "block" listed here is the thousands part of the radio ID - block 4001 is radio IDs from 4001000 to 4001999, and so on.
