'''Caller identification''' ('''Caller ID''') is a [[telephone]] service, available in analog and digital telephone systems, including [[voice over IP]] (VoIP), that transmits a [[caller (telecommunications)|caller]]'s telephone number to the [[called party]]'s telephone equipment when the call is being set up.  The caller ID service may include the transmission of a name associated with the calling telephone number, in a service called [[Calling Name Presentation]] (CNAM). The service was first defined in 1993 in [[International Telecommunication Union]]{{snd}}Telecommunication Standardization Sector (ITU-T) Recommendation Q.731.3.<ref name="auth_callerid">{{cite journal |url=https://adamdoupe.com/publications/ieee-comm-std-callerid.pdf |title=Toward Standardization of Authenticated Caller ID Transmission |website=[[IEEE]].org |last1=Tu |first1=Huahong |last2=Doupé |first2=Adam |last3=Zhao |first3=Ziming |last4=Ahn |first4=Gail-Joon |date=September 2017 |access-date=February 27, 2019 |archive-date=January 9, 2022 |archive-url=https://web.archive.org/web/20220109191027/https://adamdoupe.com/publications/ieee-comm-std-callerid.pdf |url-status=live }}</ref>

The information received from the service is displayed on a telephone display screen, on a separately attached device, or on other displays, such as cable television sets when telephone and television service is provided by the same vendor. Value to society includes allowing suicide-prevention hotlines to quickly identify a caller, and enabling businesses (for an example, restaurants and florists)
	to quickly have confidence in telephoned orders.<ref name=OKonID1992NYT/> The customer has control as to whether one's full name or merely first initial appears, a choice that to avoid a fee must be selected when the initial listing is generated.<ref name=InitialsNYT>{{cite news
