Editing Caller ID (section)

===United States===
In the United States, telemarketers are required to transmit caller ID.<ref>[http://hraunfoss.fcc.gov/edocs_public/attachmatch/FCC-03-153A1.pdf 18 FCC Rcd 14014] {{Webarchive|url=https://web.archive.org/web/20130225210405/http://hraunfoss.fcc.gov/edocs_public/attachmatch/FCC-03-153A1.pdf |date=February 25, 2013 }} (FCC, July 3, 2003) at para. 173 ''et seq''.</ref>  This requirement went into effect on January 29, 2004.<ref>47 C.F.R. § 64.1601(e).</ref> It is generally illegal to spoof Caller ID if done "with the intent to defraud, cause harm, or wrongfully obtain anything of value". The acts are prohibited under [[Truth in Caller ID Act of 2009]].

Courts have ruled that caller ID is admissible.<ref>State v. Schuette, 273 Kan. 59, 44 P.3d 459 (Kansas 2002)</ref>  Providers are required by FCC rules to offer "per-call" blocking of caller ID to their customers. Legislation in the United States in {{As of|2007|alt=2007}} made [[caller ID spoofing]] illegal for fraudulent purposes.

In March 2017, the FCC approved a new rule that would allow telecommunication companies to block [[robocall]]ers that use fake caller ID numbers to conceal their true location and identity. The rule means telecommunication companies can block robocallers at the network level, long before a call passes through a carrier's network and arrives at a subscriber's house or business.<ref name="network_block">{{cite web |title=T-Mobile kicks off industry robocall war with network-level blocking and ID tools |first=Paul |last=Sawers |url=https://venturebeat.com/2017/03/24/t-mobile-kicks-off-industry-robocall-war-with-network-level-blocking-and-id-tools/ |publisher=[[VentureBeat]] |date=March 24, 2017 |access-date=November 23, 2019 |archive-date=February 15, 2020 |archive-url=https://web.archive.org/web/20200215075400/https://venturebeat.com/2017/03/24/t-mobile-kicks-off-industry-robocall-war-with-network-level-blocking-and-id-tools/ |url-status=live }}</ref> T-Mobile was the first major US carrier to announce plans to implement blocking technologies based on the new rule.<ref name="network_block" /><ref>{{cite web |title=Apple, Google, Microsoft join 'strike force' to fight robocalls |url=https://money.cnn.com/2016/08/19/technology/robocall-strike-force/ |first=Seth |last=Fiegerman |website=[[CNN Business]] |date=August 19, 2016 |access-date=November 23, 2019 |archive-date=May 14, 2018 |archive-url=https://web.archive.org/web/20180514035451/http://money.cnn.com/2016/08/19/technology/robocall-strike-force/ |url-status=live }}</ref>

Starting in mid-2017, and with intended culmination in 2019, the FCC pushed forward Caller ID certification implemented via a methodology of [[SHAKEN/STIR]].<ref>{{cite web |url= https://www.fcc.gov/call-authentication |title= Combating Spoofed Robocalls with Caller ID Authentication |publisher= [[FCC]] |date= 2017 |first= Ajit |last= Pai |access-date= February 16, 2019 |archive-date= February 16, 2019 |archive-url= https://web.archive.org/web/20190216102558/https://www.fcc.gov/call-authentication |url-status= live }}</ref><ref>{{cite web |url= https://arstechnica.com/tech-policy/2019/02/ajit-pai-orders-phone-companies-to-adopt-new-anti-robocall-tech-in-2019/ |title= Ajit Pai orders phone companies to adopt new anti-robocall tech in 2019 |publisher= Arstechnica |date= Feb 14, 2019 |first= Jon |last= Brodkin |access-date= February 16, 2019 |archive-date= February 15, 2019 |archive-url= https://web.archive.org/web/20190215191546/https://arstechnica.com/tech-policy/2019/02/ajit-pai-orders-phone-companies-to-adopt-new-anti-robocall-tech-in-2019/ |url-status= live }}</ref>
