N.Y. Comp. Codes R. & Regs. tit. 19 § 206.15
All Commission bulletins and notices to any licensee, permit holder or otherwise authorized person or entity shall be addressed and sent to such licensee at the registered address of such licensee. The registered address of any licensee shall be his or her address or email address as specified in his or her application for a license, and in the event any licensee changes his or her address or email address, he or she shall promptly file with the Commission an appropriate change-of-address rider or amendment to such application. All licensees are bound by the notices and bulletins sent to their registered addresses, and the Commission need not entertain any plea or request based upon a contention that such notice or bulletin was not sent to any other address of the licensee. Licensees shall be deemed to have received proper notice of Commission bulletins and notices so distributed.
