888.com has not appointed a retained agency since it split with Frank PR in 2006.
888.com is part of 888 Holdings, which operates several gambling websites. A brief was sent out last week from the company's head office in Israel.
The process is being managed by Leslie Hassoun, social and offline marketing manager at 888 Holdings.
In 2013 888 Holdings handed its financial and corporate PR account to Hudson Sandler.
888 Holdings was unable to comment at the time of publication.
