As of 2015, there is no timetable for when personalized Green Dot cards must be activated. However, since temporary cards cannot be used for ATM transactions and may carry other limitations, customers should activate them upon receipt, according to information found on the Green Dot FAQ page.
Personalized Green Dot cards typically arrive within seven to 10 business days after temporary cards purchased in store are registered, and they are good until their expiration date. For security purposes, card holders must visit Greendot.com/activate or call 1-866-795-7605, explains Green Dot. Once a personalized card is registered, all funds from the temporary card are immediately transferred to the new card and the temporary card is closed.
