How to Activate Your Prepaid MasterCard Online

A prepaid MasterCard works like a debit card; you can use it to make purchases or pay bills wherever MasterCard is accepted. But you must activate a new card before you can use it. Activation is simple to do online.

Online Activation

Requirements for activating a prepaid MasterCard vary depending on the issuing company, but you can activate most cards online.

  1. Visit the online activation website indicated in your card's packaging.
  2. Enter your activation number and PIN, which are provided with the card.
  3. Click the submission button, such as "Activate" or "Submit."
  4. Remove any stickers on your card and sign it if indicated, and your card should be ready for use.



If you can't find the packaging information that came with your card, call the customer service number printed on the back of the card for guidance.

Register for Other Benefits

After you activate the card, you can register online for additional benefits, such as theft protection and the ability to reload the card with additional funds. Usually you can register the card on the same website you used for activation. Check your card's packaging for any details that apply to your particular card. Registration typically entails entering personal information, including your name and address. You'll also need government-issued identification, such as a driver's license or state-issued ID, to register for the reload and protection features.
