Welcome to

The purpose of this site is to stream live Baltimore City Police Department (BPD) radio transmissions for all to hear.

To help understand what you’re hearing, check out our list of 10-codes and a guide to unit IDs.


Currently, I only have one scanner, a Uniden BCD396XT, tuned to receive all standard BPD communications. We do not broadcast SWAT-type operations if on dedicated channels, narcotics/CID investigations or other tactical operations. The scanner is connected to a computer running Windows 7 and we use ProScan software to stream the audio to

While I do my best to make sure that the website and the radio run without interruption, there will be hiccups and problems. Feel free to send criticisms and advice to me at You can also find updates, links, and other information on Facebook and Twitter

BPD Unit IDs

First digit is district, second character is shift, third is sector and fourth is post. 6A32 would be a Northwest midnight unit in sector 3 on post 2 and 2C23 would be Southeast evening unit in sector 2 on post 3.

Lieutenants are 09 and Sergeants are 10, 20, etc., 91 and 92 are wagons and 99 is desk. So, 2C23′s Sergeant would be 2C20 and his Lieutenant 2C09. If a unit gets a warrant confirmation from 2C99, then 2C91 or 2C92 would do the transport. 200 would be the district Major.

Flex and District Ops units are numbered differently. They are numbered for each district as *1** and *2**. Northwest be something like 6117 or 6234. Again any number ending in 0 is a Sergeant and 09 a Lieutenant. Any numbers over *3** are Citywide units.

  • 64xx is Homicide
  • 65xx is Violent Crimes Task Force
