Editing Caller ID (section)

==Uses==
===Telemarketing===
Telemarketing organisations often spoof caller ID. In some instances, this is done to provide a "central number" for consumers to call back, such as a toll-free number, rather than having consumers call back the outbound call center where the call actually originated.  However, some telemarketers block or fraudulently spoof caller ID to prevent being [[call tracing|traced]]. It is against United States federal law for telemarketers to block or to send misleading caller ID.<ref>{{cite web|url=http://edocket.access.gpo.gov/cfr_2010/octqtr/pdf/47cfr64.1601.pdf|title=47 CFR 64.1601}}</ref>  Individuals may file [[civil suit]]s and the [[Federal Communications Commission]] (FCC) can [[Fine (penalty)|fine]] companies or individuals for illegally spoofing or blocking caller ID.<ref>{{cite web |title=Caller ID Spoofing |url=https://www.fcc.gov/consumers/guides/spoofing-and-caller-id |publisher=Federal Communications Commission |access-date=28 January 2019 |date=26 September 2018 |archive-date=January 29, 2019 |archive-url=https://web.archive.org/web/20190129011835/https://www.fcc.gov/consumers/guides/spoofing-and-caller-id |url-status=live }}</ref>

===Mobile providers===
Most mobile phone providers used the caller ID to automatically connect to voice mail when a call to the voice mail number was made from the associated mobile phone number, bypassing the need to enter a password.  While this was convenient for many users, because of spoofing, this practice has been replaced by more secure authentication by many carriers.
