To activate your card and set up a PIN, please call 800-631-3197 or 1-727-540-9434 when outside the US. Be prepared with the primary cardholder's date of birth (mm/yy), zip code, and 3-digit security code (same for each cardholder) from the back signature panel of the card. We encourage you to change the PIN to something easy to remember but difficult for others to identify.
