No. Unvalidated Hop tickets (paper tickets with electronics inside) are no longer sold. Hop Fastpass has replaced unvalidated tickets. Instead of purchasing tickets, you can load the equivalent value to your Hop card and earn your way to a day pass, never paying for more than you use.
If you currently have old unvalidated tickets, they can be used up to 3 years from the purchase date. When you first tap an unvalidated ticket, the fare is activated and the time remaining on your ticket is displayed on the Hop reader. You can also check your time remaining on the Hop website, using the Hop app or by phone at 1-844-MYHOPCARD (694-6722).
