Final answer:
Caller ID and robocalls are the two disclosures that must be given on every phone call.
Step-by-step explanation:
The two disclosures that must be given on every phone call are Caller ID and in some cases, prerecorded messages known as robocalls.
Caller ID is a feature that allows the recipient of a call to see the phone number or name of the calling party. This allows individuals to decide whether to answer the call or not based on the displayed identity.
Robocalls are prerecorded messages that are automatically dialed and played back by automated phone systems. These calls must disclose their identity and purpose at the beginning of the call to comply with regulations.
