Does IEEE have a preferred or required conference manuscript template?

IEEE strongly encourages the use of conference manuscript templates. The purpose of a conference template is to provide a consistent format for papers appearing in the conference proceedings. 

The use of the conference manuscript templates provided by IEEE will greatly reduce the chance for errors in the metadata visible in IEEE Xplore®, and IEEE's downstream Indexing partners. Errors may result in delays in posting or in making any approved corrections, or in some cases, may simply persist. Using the templates is one of the ways to reduce errors.

IEEE conference templates contain guidance text for composing and formatting conference papers. Please ensure that all guidance text is removed from your conference paper prior to submission to the conference. Failure to remove template text from your paper may result in your paper not being published.
