Communications on Number Theory and Combinatorial Theory (CONTACT) is an open access journal that aims at providing a fair review process and publishing original research articles in the areas of number theory and combinatorics. To achieve this, manuscripts submitted to the journal will be peer-reviewed in a double-blind format.

CONTACT publishes papers on a rolling basis, with one regular volume per year. In addition to regular volumes, we may occasionally publish special issues. Articles are published at the time of final acceptance. There is no publication charge for any accepted articles.

Information for authors can be found on the Journal Policies page.
