Call the automatic Emerald card activation hotline at 1-866-353-1266. Have your Emerald Prepaid MasterCard in hand when you call.
Provide the 16-digit card number found on the back of your card and follow the prompts.
Create a four-digit PIN (personal identification number). This will be the number you use each time you use your Emerald card to remove funds from an ATM or to pay a cashier using a debit card machine.
Write down the PIN you selected. Store this PIN in a different location than your Emerald card to avoid unauthorized use.
Sign the back of your Emerald Prepaid MasterCard.
