ANI is conceptually and technically different from caller ID service.<ref name=ForF1992NYT/> A caller's telephone number and line type are captured by ANI service even if [[Caller ID#Blocking|caller ID blocking]] is activated. The destination telephone company switching office can relay the originating telephone number to ANI delivery services subscribers. Toll-free subscribers and large companies normally have access to ANI, either instantly via installed equipment, or from a monthly billing statement. Residential subscribers can obtain access to ANI information through third party companies that charge for the service.<ref>{{cite web |title=TrapCall Displays Blocked Numbers on Your Caller ID |url=https://gizmodo.com/5155206/trapcall-displays-blocked-numbers-on-your-caller-id |first=Sean |last=Fallon |website=Gizmodo |date=2009-02-17 |access-date=2021-06-26 }}</ref>

ANI is generally not transmitted when a call is operator assisted; only the area code of the last switch to route the call is sent.{{cn|date=November 2022}}
