If you registered your card at myhopcard.com or on the Hop app, your account balance is protected in case your card is lost or stolen. (Just remember to report it to us as soon as possible!) We can transfer your account balance to a replacement Hop card. Pick up a new card at a Hop retail location then give us a call at 1-844-MYHOPCARD (694-6722). New and replacement cards cost $3.
