Where I live in Essex County there are some towns like Maplewood and Irvington that use this type of numbering system, but the rest of the county like Orange, West Orange, etc. do not follow it.
I used to be a firefighter in Highland Park (Middlesex County). Our fire station (#37) used the county numbering system for the station, but we had our own apparatus numbers that did not follow a county system.
