Year 65 (LXV) was a common year starting on Tuesday (link will display the full calendar) of the Julian calendar. At the time, it was known as the Year of the Consulship of Nerva and Vestinus (or, less frequently, year 818 Ab urbe condita). The denomination 65 for this year has been used since the early medieval period, when the Anno Domini calendar era became the prevalent method in Europe for naming years.

Caller ID (caller identification, CID), also called calling line identification (CLID), calling number delivery (CND), calling number identification (CNID) or calling line identification presentation (CLIP), is a telephone service, available in analog and digital phone systems and most voice over Internet Protocol (VoIP) applications, that transmits a caller's number to the called party's telephone equipment during the ringing signal, or when the call is being set up but before the call is answered. Where available, Caller ID can also provide a name associated with the calling telephone number. This service is called CNAM. The information made available to the called party may be displayed on a telephone's display, on a separately attached device, or personal computer.

The Singapore telephone numbering plan, also known as the National Numbering Plan, is regulated by the Numbering Management Department of the Infocomm Development Authority of Singapore (IDA), taking over the role from the Telecommunications Authority of Singapore upon its formation in December 1999.
