Why Doesn’t My BlockFi Prepaid Card Work on MyPrepaidCenter?

Issue

After receiving a BlockFi reimbursement prepaid card from MyPrepaidCenter, the card would not work anywhere. Online and in-store payments failed, making the card effectively useless.

Probable Cause

The card can get blocked for two common reasons:

  1. Clicking too fast while trying to activate or use it — the system mistakes you for a bot and blocks the card.
  2. Incorrect activation or usage — if you try to add the card directly to a wallet like Google Pay or Apple Pay without correctly setting it up, the card may be permanently blocked.

Solution

Here’s the step-by-step process that finally worked:

  • Go to MyPrepaidCenter and activate your card.
    • After activation, you’ll see the full card details (number, expiration, CVV).
  • Download the MyCardWallet app by Blackhawk Network (available on App Store/Google Play).
    • Open the app, click Add Card, and follow the instructions.
  • Once added to MyCardWallet, you can then safely connect it to Google Pay, Apple Pay, or other services.
    • Important: never try to add the card directly — always go through MyCardWallet first to avoid auto-blocks.

If your card is already blocked, unfortunately the only fix is to call the MyPrepaidCenter helpline and request an unlock.
