Here in Zone 2, i hear an OPP officer log in and say he will be for example.. "3r603" or something similar, and the comm center will respond and say that ID has already been taken, and offers him another ID such as "3r604". Has anyone else heard this type of response before. Which makes me believe that the ID is not always the same, but perhaps given out in a sequential order to the first person who logs in, even though he or she might have had a different one the day before. Once that ID is logged off it becomes available for the next officer that follows that classification of log in. This is just an assumption on my part, perhaps someone can clarify or give more information
