You should have your UGACard replaced by coming to the UGACard office during regular business hours. When having a replacement card made you must provide some photo identification (driver's license, etc) or provide two other documents with your name preprinted and have a witness sign your form.
After replacing your UGACard you must go to the Bulldog Bucks office to have your account reactivated with your new card number. This will also reactivate your card to be used with student athletic tickets.
