  In this work, we present an exact analysis of two-dimensional noncommutative
hydrogen atom. In this study, it is used the Levi-Civita transformation to
perform the solution of the noncommutative Schr\"odinger equation for Coulomb
potential. As an important result, we determine the energy levels for the
considered system. Using the result obtained and experimental data, a bound on
the noncommutativity parameter was obtained.
