# name (urban.urb)

The name of the urban land type is a primary key referenced by [urban](/io-docs/introduction-1/landuse-and-management/landuse.lum/urb_ro.md) in [**landuse.lum**](/io-docs/introduction-1/landuse-and-management/landuse.lum.md). All names in the **urban.urb** database must be unique.
