What it requires

If you initiate telephone calls or messages to encourage the purchase or rental of, or investment in, property, goods or services, transmit caller identification information with each one: either the calling party number or ANI and, when your carrier makes it available, your name (47 CFR 64.1601(e) and (e)(1)).
You may substitute the name of the seller on whose behalf the call is placed, and the seller's customer service telephone number, for the name and number used in or billed for making the call, and the number provided must permit any individual to make a do-not-call request during regular business hours (47 CFR 64.1601(e)(1)).
Do not block the transmission of caller identification information on a telemarketing call (47 CFR 64.1601(e)(2)); a tax-exempt nonprofit organization is not required to comply (47 CFR 64.1601(e)(3)).

Legal information, not legal advice. This is LexLint's own research summary of a public legal source, and it creates no attorney-client relationship. For decisions that matter, consult qualified counsel in the relevant jurisdiction. About LexLint

A person or entity that engages in telemarketing must transmit caller identification information. The caller identification information must include either the calling party number (CPN) or ANI and, when the telemarketer's carrier makes it available, the name of the telemarketer.

A telemarketer does not violate the paragraph by substituting the name of the seller on whose behalf the call is placed, and the seller's customer service telephone number, for the name and number used in or billed for making the call. The telephone number so provided must permit any individual to make a do-not-call request during regular business hours. A person or entity that engages in telemarketing is prohibited from blocking the transmission of caller identification information.

Tax-exempt nonprofit organizations are not required to comply with the paragraph. Telemarketing means the initiation of a telephone call or message for the purpose of encouraging the purchase or rental of, or investment in, property, goods, or services, which is transmitted to any person.
