Prerecorded telemarketing messages in New York require the highest level of consent: prior express written agreement with the customer's telephone number AND signature. The agreement must clearly disclose its purpose (authorizing prerecorded calls), cannot be a condition of purchase, and must specifically identify the seller authorized to make such calls. This is one of the most detailed prerecorded consent requirements at the state level. Civil penalty up to $2,000 per prerecorded call in violation. Federal TCPA layered on top. EBR exemption is limited — existing customers still need written consent for prerecorded commercial messages.
