The PIN, or Personal Identification Number, is a four-digit numeric code assigned to the Business Prepaid card account and only known to you. If you've been issued with the Single Load card your preselected PIN is under the scratch panel on the back of the card. If you have been issued with the Multiload or MultiloadPLUS cards, you will need to log into the Cardholder Portal to activate your card by selecting a PIN. You can use your PIN to complete your purchases at point-of-sale and for ATM transactions.
