I already have a Spare5 account. What happened to the PayPal account that was associated with my Spare5 account? Can I change that account?

Your existing PayPal account is still linked to your Spare5 account.

However, the PayPal account name must exactly match the name on your submitted photo ID.

If the name on your PayPal account does not exactly match your photo ID, you will get one opportunity to update it.
