So I've noticed a common theme in unit numbering from my listening, but I can't seem to nail it all down.
When using a 4 digit number, usually an Engine will be in the xx9x series (such as Engine 5691 / Engine 6692), a truck is a xx4x series (Truck 6645 / Truck 5342).
What I'm trying to determine is where is this laid out in stone? Who documents this? I can't find any kind of numbering guide in ICS or on Firescope.
I'm in SLO County if it matters, but it seems too organized to be a county-wide system? To be even more confusing, SLO City (SLO) doesn't respond with a four digit ID when responding auto/mutual aid and neither does Santa Maria City (SMR)--(SLO City Engine 5 / Santa Maria Engine 4) Why the differences?
In addition, who assigns the first two digits? I know 66 = FIV, 53 = MRB, 56 = CAY, etc? Who is 57?
Can someone please help clarify these questions that have been nagging at me (no joke).
