Please be aware that several financial institutions are experiencing an increase in fraudulent activity. Criminals are using phone calls, text messages, social media and email to impersonate businesses (including Sunmark) as a means of stealing personal information from our members.  Some of these methods have become very sophisticated, mimicking legitimate communications from financial institutions, and are quite challenging to identify as scams. Sunmark will never ask for your personal or account information (including passwords) via email, text message, or phone call. When in doubt, please call us directly at 866-SUNMARK.
