What do I use for a licensee identifier?

It depends on what type of purchase was made.  However, if you have purchased SSIS+ Ultimate Subscription via Paypal, you will receive a Subscription Number.  If you purchased a Perpetual License or purchase order, a custom Licensee Identifier will be generated and sent by COZYROC staff.
