Your customer PIN
Your unique 4-digit PIN is used to identify and authenticate your Fidium account and any changes made to your account. If someone other than you is accessing or making decisions about your account, they’ll need your PIN so we know they have your permission to do so. If you can’t remember your PIN, or can’t find it, you may change it at any time by calling 1.844.4.FIDIUM (1.844.434.3486).
