What is the last number range for identified units?

The last number range for identified units is 0910-0949. This range likely represents a specific series designated for units that have been categorized as belonging to a particular type, service, or function within the dispatch system. It is important to understand that the identification of unit numbers can follow a structured hierarchy, with lower ranges typically corresponding to earlier designs or usages and higher ranges representing newer or less frequently employed classifications.

In this case, the selected range (0910-0949) indicates the specific units that have been established and allocated within that range, making it the last set before moving onto different ranges. Understanding how these ranges are assigned can aid in efficient communication and dispatch operations, ensuring responders are aware of the unit's capabilities and roles.

The other options represent different number ranges that would not be considered the final range for identified units. Thus, while they may hold significant roles within the dispatch system, they do not specify the most recent or conclusive range as indicated in the question.
