# Attestation is not an ANI field · Learn it in 5 minutes

- Certified Caller is Five9's published STIR/SHAKEN program, tied to FCC and CRTC expectations. A campaign profile that overrides ANI changes what you present. It does not, by itself, mean the call is attested.
- Say 'we set local ANI' or 'we are in Certified Caller.' If you cannot point at the Certified Caller page for the second sentence, do not say it.
