**Abstract:** We present recent results on dynamical chiral symmetry breaking in (2 + 1)-dimensional QED with *N* four-component fermions. The results of the 1/*N* expansion in the leading and next-to-leading orders were found exactly in an arbitrary nonlocal gauge.

**Keywords:** (2 + 1)-dimensional QED; dynamical chiral symmetry breaking; 1/*N* expansion; non-local gauge
