What does the number on correctional keys signify?

The number on correctional keys is used to represent the access level granted. This numbering system helps ensure that only authorized personnel can access specific areas of a correctional facility. Each key is designated a particular number that correlates with restrictions on access, thereby enhancing security and control within the institution. This system is vital for maintaining order, as it clearly indicates which personnel are permitted to enter certain locked areas, such as individual cells, administrative offices, or secure zones.

In the context of correctional facilities, assigning a unique number to each key allows for organized management and accountability. It ensures that each key corresponds to specific locks, further ensuring that unauthorized access is minimized. The identification of keys by their numbers also facilitates better inventory control and key management practices within the facility.
