N.Y. Comp. Codes R. & Regs. tit. 9, § 5005.1 – Subscription program.

(a) A subscription program may be established at the discretion of the commission for any commission game(s). The subscription program may permit a subscriber to play the same game character selections for a period of consecutive drawings over a stated period in such games as the commission may decide.
(b) Entry into a subscription program will require the completion and submission of either a paper or electronic version of:
1. (1) a subscription application form; or
2. (2) a subscription renewal form.
  The subscriber may provide the subscriber’s social security number on the respective application form so that prizes requiring Federal reporting or withholding may be automatically sent to the winning subscriber. An application for a group subscription must contain the names and addresses of each group member.
(c) By providing the social security number, the subscriber is authorizing the commission to retain and use the number for the purpose of tax reporting and any other lawful purpose of the commission. No group may exceed 10 members if such group’s application was made by mail.
