Most expiring cards will automatically be reissued, meaning you will not have to request/opt-in for a new card.
For customers that haven't engaged with their Acorns debit card for 90+ days, an opt-in is required. An email will be sent out to confirm if a card should be shipped out. No action is required if you do not wish to receive a new card.
Any customers that do not renew will have their Acorns Checking accounts closed at the end of the expiration month.
