What must a facility use to clearly identify each room?

A facility must use a room number or room name to clearly identify each room because these identifiers provide a straightforward and standardized way to locate and address specific areas within the facility. Room numbers are universally recognized and are essential for navigating the layout of the building, facilitating efficient communication among staff, residents, and visitors. This identification method directly supports both operational efficiency and resident safety, ensuring that care staff can promptly find the appropriate rooms to provide services or respond to residents' needs.

While other options could contribute to identifying rooms—such as room descriptions providing context, resident identifiers ensuring that staff can recognize and relate to individual residents, or even color-coded signs enhancing wayfinding—these methods do not offer the immediate clarity and direct navigational aid that room numbers or names provide. Room numbers or names serve as the primary and most effective means of identifying and locating rooms within a facility.
