BOSTON — The words “free” and “fun” are not the first things that come to mind when talking about the Massachusetts Department of Administration and Finance.

Yet a typo in a phone number on a news release issued by the agency Wednesday sent media inquiries to a “free and fun party line” advertising adult hotlines.

The Boston Herald reported that the release declaring October as Cyber Security Awareness Month mistakenly substituted area code “617” instead of “857” in a spokesman’s number.

Department chief of staff Dominick Ianno said the error, which was quickly corrected, was an obvious typo since “nothing is free and fun in the Executive Office for Administration and Finance.”

The incorrect number also instructed callers on how to set up small businesses to receive commissions for satellite TV referrals.
