Due to a redefining of post towns by the Royal Mail in 2003, Noctorum is identified as being within Prenton (which is in fact a geographically separate suburb of Birkenhead), yet this was only a postal change and Noctorum itself still remains a part of Birkenhead.

[4] This may be in reference to Bidston Hill,[citation needed] of which Noctorum is situated on its western slope.

[citation needed] Noctorum appears as Chenoterie (Norman French) in Domesday Book.

Noctorum is situated on the western side of the Bidston to Storeton ridge, with the area at an elevation of between 10–60 m (33–197 ft) above sea level.

The current Member of Parliament is Mick Whitley, a Labour representative.

Noctorum Lane is the site of the Grade II listed buildings Mere Hall and Rathmore.
