What we are pointing to is that many of these 3 digit numbers are a partial of the NTIA issued Call Sign.
ie:
a.) 620 on a Maine Border Patrol channel is KAD620 aka Houlton
b.) 801 on a Rhode Island/Massachusetts FBI freq is KCB801 aka the Providence RA
c.) 220 on a Florida CBP/ICE channel is KAD220
Once the OP returns and posts the Freq/Tone he is hearing with "215" then we can move on with this topic. Otherwise right now it is speculation

An agency having a 5 or 6-character alphanumeric call sign is not the same as the call signs being used by an individual officer/agent. I have yet to hear any federal, state, or local LE/EMS/fire traffic in which such a call sign was used, with the exception of one state police repeater that periodically broadcasts a call sign in Morse code.Everything else involves a 2-3-digit number, sometimes with a descriptor in front.
Examples:
"Engine 22" "Medic 11" (local fire department)
"Romney" (state police dispatch)
Everything else I hear is 2 or 3-digit numbers.
